Assessment of diversity of plant species, composition, structure and regeneration status in Gondar Zuria District, Ethiopia

This study assesses the composition, arrangement, and state of regeneration in Gondar Zuria District. The two transect lines over the gradient were set up using a systematic random sample strategy in order to gather the number of species and their diameter for tree species in DBH (cm). The distance between the sample plots was 50 m, and the transect lines were 50 m apart. 12 circular plots were used in the total sample area of the botanical garden, and the sizes of the circular plots were 6.5 m for trees, 4.5 m for saplings, and 2.5 m for seedlings. Using the important value index and the diameter at breast height, the pattern of plant structure displays an inverted J shape. A review of the botanical garden’s plant species’ regeneration status revealed that, of the tree and shrub species, 6.25% had fair regeneration status and 25% had poor regeneration quality. While 56.25% of plant species that were only available as saplings or seedlings were regarded as “new” at the botanical garden, a total of 25% of plant species were not regenerating at all. At the study site, the species diversity as determined by the Shannon-Weiner (H’) index was 1.58. But this value shows the species diversity is included in the low biodiversity range unless they are well managed from disturbance. The species composition of the site shows a few species; only 16 plant species were found. A high number of individual species are found in the Leguminosae family.

A Review of Therapeutic and Medicinal Uses of Fenugreek (Trigonella foenum-graceum L.)

Current lifestyle and excessive use of synthetic fertilizers in agriculture field promote an unhealthy lifestyle that urges the researchers looking for a healthy and beneficial diet. Numerous crop plants have nutritional, functional, nutraceutical, and therapeutic properties. Fenugreek (Trigonella foenum gracium) is a popular crop known for these qualities and is beneficial in the human diet. It is an annual plant from the Leguminosae family that is commonly grown in the Mediterranean and Asian countries. It is mostly grown for its spices, though it can also be used for food (feed) and medicinal (antioxidant, antibacterial, anti-inflammatory, and hypoglycemic properties). Fenugreek is famous for its versatile uses, grown under moderate conditions (drought and salinity), white flowering herb, and self-pollinated plant. Fenugreek composition consists of various nutrients like vitamins, minerals, proteins, lipids, fibre, amino acids, and bioactive compounds that are used for medicinal purposes. Due to higher fibre content fenugreek is called a food stabilizer and emulsifying agent for changing food texture. Fenugreek has numerous health benefits, including the ability to lower blood sugar, heart problems, menstrual cramps, anti-cancer, reduce inflammation, and support healthy skin and hair. This review highlights the nutritional value of fenugreek with various health and medicinal benefits. Despite its multiple advantages, this review paper also discussed health problems associated with the usage of fenugreek, such as allergies and possible adverse effects linked with fenugreek use.

A Review on Phytochemical Constituents Used as Current Treatment Strategies for Neurodegenerative Disease.

In today's time, a diversity of neurodegenerative diseases that widely affect the CNS causing insufficiency in particular brain processes such as memory, mobility, and cognition due to the moderate loss of CNS neurons. This review emphasizes different phytochemical constituents used widely for the prevention or treatment of various neurodegenerative diseases such as Alzheimer's disease (AD) and Parkin-son's disease (PD). Berberin (BBR), which is an isoquinoline class of alkaloid and isolated from the plant Hydrastis condenses and Berberis aaristata, has both acetylcholine esterase (AChE) inhibiting properties as well as monoamine oxidase (MAO) inhibiting properties involved in the betterment of AD by decreasing the production of reactive oxygen species (ROS). Like BBR, Physostigmine, isolated from the Physostigma venenosum / Calabar bean and belongs to the family Leguminosae, and Morphine, isolated from the plant Papaver somniferum / Opium poppy or Breadseed poppy, also has a significant impact on the management and treatment of AD and PD by reducing both neuroinflammation and pro-inflammatory cytokines production. Morphine bineurodegenerative diseases with μ-opioid receptor (MOR) in CNS elevate GABA levels in the synaptic cleft of the brain and reduces the neurotoxicity via stimulation of MOR. It has been discovered that physostigmine improves cognitive function in AD patients and reduces α-synu-clein expression in PD neural cell lines. Isorhyncophylline (IRN) is a Chinese herbal medicine isolated from the plant Uncaria rhyncophylla which provides neuroprotective efficiency against neurotoxicity that occurs by amyloid β (the main component of amyloid plaques) found in the brain of people with AD.

Astragalus membranaceus (Fisch.) Bge (AM) is a medicinal herb plant belonging to the Leguminosae family. In this study, we present a chromosome-scale genome assembly of AM, aiming to enhance the molecular biology and functional studies of Astragali Radix. The genome size of AM is about 1.43 Gb, with a contig N50 value of 1.67 Mb. A total of 98.16% of the assembly anchored to 9 pseudochromosomes using Hi-C technology. The assembly completeness was estimated to be 97.27% using BUSCO with the long terminal repeat assembly index (LAI) of 16.22 and quality value (QV) of 48.58. Additionally, the genome contained 67.98% repetitive sequences. Genome annotation predicted 29,914 protein-coding genes, including 73 genes involved in the flavonoid biosynthetic pathway and 2,048 transcription factors. The high-quality genome assembly and gene annotation resources will greatly facilitate future functional genomic studies in Leguminosae species.

Purification and partial characterization of a new melibiose-specific lectin from Bauhinia catingae Harms

Lectins are ubiquitous proteins that selectively bind to carbohydrates, serving as vital models for understanding protein-carbohydrate interactions. While extensively distributed across various life forms, plant lectins, especially from the Leguminosae family, have garnered significant attention. However, limited research exists on lectins from the Caesalpinioideae subfamily, suggesting a source of untapped biotechnological potential. This underscores the imperative for further exploration, particularly in isolating lectins from the Bauhinia genus, which remains relatively understudied, despite harboring lectins with diverse characteristics and promising biotechnological activities. In this study, a novel lectin extracted from Bauhinia catingae Harms seeds (BCL) was isolated in three chromatographic steps. BCL exhibited affinity for galactose and derivatives, akin to other Bauhinia lectins, with SDS-PAGE confirming its molecular weight around 30 kDa. Notably, BCL demonstrated stability across temperature and pH ranges and lacked metalloprotein characteristics. Electrospray ionization mass spectrometry revealed a partial sequence covering 81 % of the total protein sequence with nearly 80 % identity to Bauhinia forficata. Structural analysis suggested a β-sheet-rich secondary structure similar to that of other lectins. Further structural elucidation of BCL is essential to unveil its full potential and applications.

Phytoestrogens Therapy for Osteoporosis Treatment Using Indonesian Medicinal Plants: A Brief Review

A problematic bone remodeling cycle is known to produce more osteoclasts than osteoblasts, making bones more fragile and this condition shows osteoporosis. In this context, estrogen deficiency in the human body is associated with the regulation of osteoporosis. Therefore, this study aimed to investigate the knowledge about basic concepts of bone, osteoporosis, phytoestrogens, and Indonesian medicinal plants for osteoporosis treatment. Data were obtained from literature on various databases including Science Direct, Wiley Online Library, Scopus, Pubmed, and Google Scholar. Adequate therapy is needed to increase estrogen content and an effective approach is to consume medicinal plants that contain phytoestrogens, which have identical structure and activity to human estrogen (17β-estradiol). The results showed that there were observations comprising in vitro, in vivo, and in silico studies on 18 Indonesian medicinal plants as antiosteoporosis treatments. The Leguminosae or Fabaceae family, which has a significant amount of isoflavones (the primary group of phytoestrogens) was found to dominate as an antiosteoporosis agent. Therefore, the development of phytoestrogens therapy from Indonesian medicinal plants must be implemented for the future treatment of osteoporosis.

Transcriptome and Metabolome Analyses Reveal the Molecular Mechanisms of Albizia odoratissima’s Response to Drought Stress

Albizia odoratissima is a deciduous tree species belonging to the family Leguminosae. It is widely distributed in the southern subtropical and tropical areas of China and has important ecological and economic value. The growth and metabolic processes of A. odoratissima are affected by drought stress, but the molecular mechanisms remain unknown. Therefore, this study investigated the physicochemical properties, gene expression, and metabolites of A. odoratissima seedlings under drought stress. The results show that, in leaves of A. odoratissima seedlings, drought stress reduced the moisture content, chlorophyll content, photosynthetic efficiency, superoxide dismutase (SOD) activity, and gibberellin (GA) and indoleacetic acid (IAA) contents while increasing the catalase (CAT) and peroxidase (POD) activities and malondialdehyde (MDA), proline, soluble sugar, and soluble protein contents. Within the CK5 (Day 5 of control group) vs. T5 (Day 5 of drought treatment), CK10 vs. T10, CK15 vs. T15, and CK20 vs. T20 groups (CK: control group; T: drought treatment), a total of 676 differentially expressed genes (DEGs) were upregulated and 518 DEGs were downregulated, and a total of 228 and 143 differential accumulation metabolites (DAMs) were identified in the CK10 vs. T10 and CK20 vs. T20 groups. These were mainly involved in the amino acid and alkaloid metabolism pathways in the leaves of the A. odoratissima seedlings. In the amino acid and alkaloid biosynthesis pathways, the relative expression levels of the AoproA (Aod04G002740, ORTHODONTIC APPLIANCE), AoOAT (Aod07G015970, ORNITHINE-OXO-ACID TRANSAMINASE), and AoAOC3 (Aod12G005010/08G003360/05G023920/08G003000/08G003010, AMINE OXIDASE COPPER CONTAINING 3) genes increased, which concurrently promoted the accumulation of arginine, proline, piperine, cadaverine, and lysine. Furthermore, some key transcription factors in the response to drought were identified in the leaves using the weighted gene co-expression network analyses (WGCNA) method. These findings reveal that A. odoratissima seedlings respond to drought stress by improving the capacities of the antioxidant system and secondary metabolism.

Saponins from Dolichos lablab seeds with anti-inflammatory activity

As one of a traditional Chinese medicine with dual applications in both medicinal treatment and dietary consumption, the mature seeds of D. lablab were reported to be rich in saponins and have a good effect on inflammatory related diseases. However, the substance basis for its anti-inflammatory activity remains unclear. Thus, a comprehensive phytochemical investigation on triterpenoid saponins from D. lablab seeds was carried out, resulting in the isolation and identification of twenty-one new triterpenoid saponins including dolilabsaponins A1–A4, B, C, D1–D3, E–M, N1, N2 and O (1–21) along with thirteen known analogs (22–34). Notably, the known saponins, 31, 32, and 34 were obtained from Leguminosae family for the first time. The 1H and 13C NMR data of saponins 24 and 28 were firstly reported here. Additionally, lipopolysaccharide (LPS)-stimulated RAW264.7 cells model was utilized to assess inhibitory activities of compounds 1–34 on nitric oxide (NO) production. The results revealed that compounds 1–3, 9, 10, 13–15, 18, 22, 23 and 28–34 significantly suppressed the elevation of NO levels in LPS-induced RAW264.7 cells at the concentration of 30 μM, exhibiting a concentration-dependent manner at 3, 10, and 30 μM. The results suggested that compounds 1–3, 9, 10, 13–15, 18, 22, 23, and 28–34 possessed potential anti-inflammatory activity. Further western blot assay demonstrated that 1, 9, 10, 13, 14, and 18 suppressed inflammatory response via down-regulated the expression levels of inflammatory factors, tumor necrosis factor-alpha and interleukin-6.

Seasonally dry tropical forests in the late Pleistocene of Mesopotamia, Argentina and their relationship to environmental changes during the Last Interglacial

ABSTRACTThe concept of seasonal forests groups structural types of vegetation that are related to climatic seasonality in the tropics of South America. Consequently, this determines the physiognomy of the vegetation, from semi‐deciduous to strongly deciduous. The strongest link between seasonally dry tropical forests (SDTFs) is their floristic composition, where Leguminosae and Anacardiaceae dominate the woody flora. The fossil records of the Neogene of northwestern Argentina reveal a list of species found in various locations and formations of the Miocene–Lower Pleistocene obtained from studies of pollen, woods (logs), cuticles, impressions of leaves and fruits. The analysis of sediments and woody structures from the Tapebicuá, Toropí/Yupoí and El Palmar Formations (Upper Pleistocene) of the Mesopotamia region allowed us to identify several pollen taxa and silicified wood fragments (mineralized). The woody and shrubby association whose current relatives characterize the SDTF is composed of the 16 fossil species described here belonging to seven families. In our samples, Anadenanthera colubrina and Myracrodruon balansae are the most significant members of the families Leguminosae and Anacardiaceae, which are dominant in the SDTF. The paleobotanical species described in this study confirm the extension of the SDTF to the province of Corrientes, coinciding with various climatic events (dry subtropical, semi‐desert and warm‐humid climate) that would have favored the development of these forests during the Pleistocene in this region. The absolute dates obtained for the Toropí/Yupoí and Tapebicuá Formations confirm their synchronicity and correlation to Marine Isotope Stage 5. The palynological analysis, the presence of Menendoxylon and the sedimentological data allow us to infer the existence of a seasonally dry humid paleoclimate in northeastern Argentina during the Late Pleistocene favorable to the development of the SDTF.

Impact of Phosphorus and Sulphur Levels on Growth Parameters of Groundnut (Arachis hypogaea L.)

Background: Groundnut, a well-recognized oilseed crop belonging to the Leguminosae family, faces several challenges in India that results in lesser productivity compared to the global average. The principal underlying cause of India’s diminished groundnut production lies in the irregular and inadequate utilization of essential nutrients. Given its status as a leguminous oilseed crop, it exhibits a heightened demand for phosphorus, calcium and sulphur, which often remains unmet, further exacerbating the problem. Methods: In a field experiment, split-plot design was employed to investigate the impact of four phosphorus levels (Control, 40, 50 and 60 kg P2O5 ha-1) and four sulphur levels (Control, 25, 50 and 75 kg S ha-1) on the growth parameters of groundnut. Results: The findings demonstrate that the utilization of phosphorus and sulphur fertilizers yielded significant improvements in various aspects of groundnut growth parameters. These improvements encompassed increased plant height, root length, improved root-to-shoot ratio on a length and weight basis, greater numbers of root nodules per plant and dry weight of root nodules per plant.

Puerariae lobatae Radix: Progress in Extraction, Separation Methods and Pharmacological Activities Research

Kudzu root (Puerariae lobatae Radix) is the tuberous root of Pueraria lobata, family Leguminosae. Kudzu root contains a variety of beneficial active ingredients such as puerarin, daidzin, daidzein, genistenin, 3′-hydroxy puerarin, β-sitosterol, stigmasterol, arachidic acid, and so on. Modern medical research shows that active ingredients in kudzu root are widely used clinically as raw materials for the treatment of hyperglycemia, non-alcoholic fatty liver disease, myocardial infarction, alcohol addiction, oxidative stress, inflammatory response, and retinal blockage due to their various pharmacological effects such as improving cardiovascular circulation, lowering blood lipids, lowering blood pressure, lowering blood sugar, being antipyretic, being estrogen-like, and relieving alcohol. China has rich resources of kudzu root, and active ingredients are usually extracted before it is made into a preparation, so whether the extraction and separation process is reasonable will directly affect the ease of preparation and the efficacy of the treatment. This paper reviews the process methods for the extraction and separation of active ingredients in kudzu root and its common pharmacological activities. The aim is to provide some references for readers to compare the advantages and disadvantages of various extraction and separation methods as well as understand the active ingredients and pharmacological activities of kudzu root.

Effect of Phosphorus and Sulphur Levels on Yield Attributes, Yield and Quality of Groundnut (Arachis hypogaea L.)

Background: Groundnut is one of the best known oilseed crops and belongs to the family Leguminosae. However, the productivity of groundnut in India is less as compared to average productivity of world due to uncertainty in monsoon rainfall and incidences of diseases, insect pests and weeds. The main cause of low groundnut production is an unbalanced and insufficient usage of nutrients. Because groundnut is a legume-oilseed crop, it has a high phosphorus, calcium and sulphur demand. Methods: A field experiment consisting of four phosphorus levels (Control, 40, 50, 60 kg P2O5 ha-1) and four sulphur levels (Control, 25, 50, 75 kg S ha-1) was laid out in split plot design to analyze their effect on pod yield, yield components, physiological and quality parameters of groundnut. Result: The results indicated the application of 60 kg P2O5 ha-1 and 75 kg S ha-1 significantly improved the pod yield and yield components except number of kernels per pod and harvest index, physiological parameters except leaf area index and all the quality parameters. However, the difference between 50 and 60 kg P2O5 ha-1 and 50 and 75 kg S ha-1 was found non-significant for most of the studied parameters.

First Report of Powdery Mildew caused by Erysiphe astragali on Sphaerophysa salsula.

Sphaerophysa salsula (Pall.) DC., also known as Yang Liao Pao, belongs to the Leguminosae family and is the only existing species in the Sphaerophysa genus. S. salsula is tolerance to cold, high salt, and alkaline soil, it is widely cultivated in China as a forage crop, and used as a Chinese folk medicine to treat hypertension (Ma et al., 2002). In 2023, signs and symptoms similar to powdery mildew were found on S. salsula planted in Tumd left (40.515°N, 110.424°E), Baotou City, Inner Mongolia Autonomous Region, China. The white powdery substance covered 90% of the leaf area, and the infected plants showed weak growth and senescence. More than 80% of plants (n=200) had these powdery mildew-like symptoms. Hyphal appressoria are solitary, conidiophores have few branches and septa. Conidia are cylindrical to clavate, 25-32 μm long and 8-15 μm wide (n=30), conidia form single subapical germ tubes, straight to curved-sinuous, with swollen apex or distinctly lobed conidial appressorium. Based on these morphological characteristics, the fungus was tentatively identified as an Erysiphe sp. (Schmidt and Braun 2020). Fungal structures were isolated from diseased leaves, and genomic DNA of the pathogen was extracted using the method described by Zhu et al. (2022). The internal transcribed spacer (ITS) region was amplified by PCR using the primers PMITS1/PMITS2 (Cunnington et al. 2003) and the amplicon sequenced by Invitrogen (Shanghai, China). The powdery mildew strain, named as KMD (GenBank accession no.: PP267067), showed an identity of 100% (645/645bp) with Erysiphe astragali, a powdery mildew reported on Astragalus glycyphyllos in Golestan, Iran (GenBank: OP806834) and identity of 99.6% (643/645bp) with Erysiphe astragali (GenBank: MW142495), a powdery mildew reported on A. scaberrimus in Inner Mongolia, China (Sun et al. 2023). Pathogenicity tests were conducted by brushing the conidia from infected S. salsula leaves onto leaves of four healthy plants, while four control plants were brushed in the same manner. All the treated plants were placed in separate growth chambers maintained at 19°C and 65% humidity, with a 16 h light/8 h dark photoperiod. Nine days after inoculation, the treated plants showed powdery mildew symptoms, while the control plants remained asymptomatic. The same results were obtained for two repeated pathogenicity experiments. The powdery mildew fungus was reisolated and identified as E. astragali based on morphological and molecular analysis, thereby fulfilling Koch's postulates. No report on the occurrence of powdery mildew on S. salsula plants has been found previously. The occurrence of this destructive powdery mildew may adversely affect the cultivation of S. salsula. Identifying the pathogen of powdery mildew will support future efforts to control and manage powdery mildew on S. salsula.

Investigating the growth promotion potential of biochar on pea (Pisum sativum) plants under saline conditions

Pea, member of the plant family Leguminosae, play a pivotal role in global food security as essential legumes. However, their production faces challenges stemming from the detrimental impacts of abiotic stressors, leading to a concerning decline in output. Salinity stress is one of the major factors that limiting the growth and productivity of pea. However, biochar amendment in soil has a potential role in alleviating the oxidative damage caused by salinity stress. The purpose of the study was to evaluate the potential role of biochar amendment in soil that may mitigate the adverse effect of salinity stress on pea. The treatments of this study were, (a) Pea varieties; (i) V1 = Meteor and V2 = Green Grass, Salinity Stress, (b) Control (0 mM) and (ii) Salinity (80 mM) (c) Biochar applications; (i) Control, (ii) 8 g/kg soil (56 g) and (iii) 16 g/kg soil (112 g). Salinity stress demonstrated a considerable reduction in morphological parameters as Shoot and root length decreased by (29% and 47%), fresh weight and dry weight of shoot and root by (85, 63%) and (49, 68%), as well as area of leaf reduced by (71%) among both varieties. Photosynthetic pigments (chlorophyll a, b, and carotenoid contents decreased under 80 mM salinity up to (41, 63, 55 and 76%) in both varieties as compared to control. Exposure of pea plants to salinity stress increased the oxidative damage by enhancing hydrogen peroxide and malondialdehyde content by (79 and 89%), while amendment of biochar reduced their activities as, (56% and 59%) in both varieties. The activities of catalase (CAT), superoxide dismutase (SOD), and peroxidase (POD) were increased by biochar applications under salinity stress as, (49, 59, and 86%) as well as non-enzymatic antioxidants as, anthocyanin and flavonoids improved by (112 and 67%). Organic osmolytes such as total soluble proteins, sugars, and glycine betaine were increased up to (57, 83, and 140%) by biochar amendment. Among uptake of mineral ions, shoot and root Na+ uptake was greater (144 and 73%) in saline-stressed plants as compared to control, while shoot and root Ca2+ and K+ were greater up to (175, 119%) and (77, 146%) in biochar-treated plants. Overall findings revealed that 16 g/kg soil (112 g) biochar was found to be effective in reducing salinity toxicity by causing reduction in reactive oxygen species and root and shoot Na+ ions uptake and improving growth, physiological and anti-oxidative activities in pea plants (Fig. 1).Figure 1A schematic diagram represents two different mechanisms of pea under salinity stress (control and 80 mM NaCl) with Biochar (8 and 16 g/kg soil).

Its fruit is a pod containing 10%-20% seeds, and the pods consist of sugars, proteins, crude fibers, minerals, vitamins, polyphenols, vitamins, and lipids. In many countries in the Middle east, carob is mainly used to prepare as a traditional drink and some kinds of confectioneries. The powders can be utilized to prepare carob juice concentrate. The systematic review of documents from clinical trials and scientific societies dedicated to traditional medicine in China has been carried out. The goal of this review article is a survey of chemical compounds, and pharmaceutical benefits of carob, especially by considering traditional medicinal sciences. Moreover, clinical trials research promotes studies to highlight and focus on the scope of application of traditional medicinal science in the growing system of medicine.

Performance, digestibility and meat quality from lambs fed diets with plantago lanceolata, Italian ryegrass or sainfoin herbages.

Plantago species, which is known to adapt to different climatic conditions, drought, temperature and different soil types. The aim of this study was to compare the effects of P. lanceolata herbage on fattening performance, rumen variables, digestibility, meat quality, meat nutrients and meat textural variables in lambs with the values of Italian ryegrass and sainfoin herbages. The lambs were fed total mix ration (TMR) with concentrated feed (about 30%) plus forage (about 70%) (P. lanceolata, PLA, Italian ryegrass (Lolium multiflorum); IRY or sainfoin (Onobrychis viciifolia) herbages, SAI). Twenty-four male lambs (Akkaraman breed) were assigned to three treatments with 8 lambs in each group. Fattening performance parameters, digestibility and carcass variables were determined. Meat quality and shelf life variables (oxidation, fatty acid profile and textural variables) was detected in the loin (Musculus longissimus), shoulder (M. deltoideus) and leg (M. semitendinosus) muscle samples, which were rested for 24 h +4°C and stored at -20°C for one week, one month, three months and six months. The dry matter (DM) intake, body weight gain, feed efficiency and carcass yield values of lambs, the DM and organic matter (OM) digestions (DMD and OMD) of TMRs, and the pH value, ammonia-nitrogen and short chain fatty acid (SCFA) concentrations of rumen fluid in lambs consuming PLA were similar to those of IRY and SAI (p > 0.05). PLA increased water holding capacity (WHC) and decreased cooking loss of meat compared to feeding with those of IRY and SAI (p < 0.05). The peroxide value (PV) and malondialdehyde (MDA) concentration increased with the stocking time in the meats (p < 0.05). Therefore, PV and MDA concentrations of shoulder, leg and loin meats up to 6th months for PLA were lower than those of IRY and SAI (p < 0.05). The linoleic acid concentration of loin and shoulder meats in PLA were higher than those of IRY and SAI (p < 0.05). The average oleic acid and ∑ω6 fatty acids concentration of meat in PLA was lower than those in IRY and SAI (p < 0.05). Atherogenic index and thrombogenic index values and palmitic acid levels of meat in PLA were similar to those in IRY, but lower than those in SAI (p < 0.05). Springiness, cohesiveness, resilience, hardness and chewiness values of the textural analysis parameters in meat of PLA were lower than those of IRY and SAI. As a result, effect of P. lanceolata on the fattening performance and rumen fermentation of lambs were similar with those of Italian ryegrass (Gramineae family) and sainfoin (Leguminosae family) forages and, it had a positive effect on meat quality (water holding capacity, cooking loss) and meat shelf life criteria (MDA, PV, fatty acid profile and textural variables). For functional lamb meat production, P. lanceolata can be included in the diet of lamb fattening.

Purification and characterization of 3-O-methyl-D-glucose from the seed coat of Vigna mungo (L.) Hepper

Vigna mungo. L (Black gram) belonging to the Leguminosae family is a most abundant source of protein for human and animal diets. Over 8.5 million tonnes of black gram are being produced worldwide, and after confiscating the endosperm for the protein source, the seed coat is dumped as agro-waste and used as feed for the cattle. This study aims to investigate and profile the metabolites in three distinct parts of V. mungo seeds: coat, cotyledon, and intact seed. Also, it has been hypothesized that sugar methylation plays a pivotal role in facilitating black gram seed germination by serving as an energy source during metabolic processes. In our study, A total of forty-nine compounds belonging to the class such as fatty acids, saccharides, triterpenes, sterols, and vitamins were detected in various parts of V. mungo seed by gas chromatography-mass spectrometry (GC-MS). Most interestingly, 3-O-methyl-D-glucose (3-OMG) was commonly detected in methanolic extract of coat, intact seed, and cotyledon with peak area percentages of 3.076, 1.157, and 1.100 %, respectively. Based on the highest peak area percentage in the coat, this compound was purified by using a silica gel column with a mesh size of 60–120 followed by Biotage SNAP cartridge KP-C18-HS (12 g). The yield and purity of the purified fractions were found to be 11.78 & 94.19 %, respectively by high-performance liquid chromatography (HPLC) analysis. Further, the mass confirmation of purified fraction containing 3-OMG (m/z - 217.06 g/mol) was done by liquid chromatography-mass spectrometry (LC-MS/MS) and reconfirmed with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF/MS). The MS/MS analysis of the fragment showed m/z 206.91 for 3-OMG which corresponds to the association of the sodium adduct. The concentration of 3-OMG was quantified as 332.65 µg/g of dry weight in the coat of V. mungo by HPLC analysis. Also, among the antioxidant assays conducted, such as DPPH, ABTS, FRAP, and NOS, it was observed that the methanolic extract of coat exhibited the most significant antioxidant activity. The 3-OMG is commonly used as a non-metabolized analogue of glucose by regulating glucose transporter, especially GLUT-4 that regulates the absorption of glucose by insulin into muscle and fat cells. This study supports the black gram seed with coat as an alternative medicine to regulate blood glucose.

Exogenous application of different antagonists and their secretory metabolites to manage root-knot nematodes in pea

Pea (Pisum sativum L.) is a grain legume, a member of the Leguminosae family. Root-knot nematodes cause severe losses ranging from 15 to 85%. Different species of nematodes including root-knot nematodes reduce the yield of pea significantly. To control root-knot nematodes biological control is a more environment-friendly approach. The main objective of the study is to assess the effect of different antagonistic microbes and their secretory metabolites to manage root-knot nematodes in peas. Through this research, we aim to identify potential biological control agents that can be used as eco-friendly alternatives to chemical nematicides, contributing to sustainable pest management practices in agriculture. For this purpose, firstly, a brinjal seedling was transplanted for inoculum development which was inoculated with infective 2nd stage juveniles of root-knot nematodes (Meloidogyne spp.) in Department of Plant Pathology research area, University of Agriculture Faisalabad (UAF). Then two pea varieties viz. Matar sabaz and Pea-2009 were sown in pots and inoculated with nematode larvae after four weeks of sowing. Moreover, the management of nematodes was done by using the antagonists and their secretory metabolites application. The data of different plant growth and nematode-related parameters was taken and subsequently analyzed using analysis of variance and least significant difference test (LSD). Results showed that the antagonist’s treatment subsequently controlled root-knot nematodes (RKNs). Maximum plant/shoot length (47 cm), root length (25.25 cm), shoot weight (22.25 g) pod length (8.50 cm), No. of secondary shoots (8) and minimum number of galls (2.5 cluster), was observed in plants treated with Bacillus spp. (T1) while maximum No. of fruits (5.75) was observed in plants treated with Pseudomonas spp. (T2). Similarly, the number of nodules (7.50 clusters) primary shoots (5) Root weight (4.6 g) was observed in plants treated with Enterobacter spp. (T3).

Evaluation of Pigeonpea Genotypes against Sterility Mosaic Disease

Pigeonpea (Cajanus cajan L.) belonging to family Leguminosae is an important leguminous pulse crop of semi-arid tropic and subtropic regions (Asia and Africa). It is also known as red gram, arhar, tur dal. The crop is affected by several phytopathogens, of which, pigeonpea sterility mosaic disease/virus, and transmissible by eriophyid mites (Aceria cajani) has been a major bottleneck. Yield losses up to 95 per cent or even 100 per cent in severe Sterility Mosaic Disease incidence were reported. Therefore, present investigation on screening of pigeon pea genotypes against the sterility mosaic disease was carried out during Kharif, 2018 at the Department of Plant Pathology, College of Agriculture, Latur. In present study, about 27 entries of pigeonpea were screened under natural epiphytotic against pigeonpea sterility mosaic disease. Of these GRG-152, ICP-2376, BRG-5, BRG-4, ICPL-15048, BSMR853, BSMR-736, BRG-1and BRG-3 were resistant; MPV-106, RVSA-16-1, IPA-16-8 and BRG-2 were moderately resistant, whereas, PUSA-2017-01, TDRG-58, ICP-8863, PUSA-2018, PUSA-2018-1, PUSA-2018-2, PUSA-2018-3 ,PUSA-2018-5, AKTE-12-04, KRG-244, PADT-16, RKPV-912, JKM-189 and TJT-501 were susceptible to Sterility Mosaic disease.
