Introducing Saffron and a few medicinal and high value plants for small farms and water deficit conditions of northern New Mexico

This document reviews the potential of cultivating saffron and other high-value medicinal and aromatic plants such as lavender, rosemary, thyme, chamomile, and Damask rose on small farms in northern New Mexico, particularly under water deficit conditions. Medicinal and aromatic plants, rich in secondary metabolites, are crucial to various industries including pharmaceuticals, cosmetics, and food. With an increasing global market for herbal products and a rising interest in traditional medicine, these plants offer economic benefits and sustainability for small-scale farmers. Northern New Mexico's diverse climate and soil conditions are suitable for growing a wide range of these plants, which are more lucrative and adaptable to dryland farming compared to traditional crops. Saffron (Crocus sativus), the most expensive herb globally, thrives in arid and semi-arid conditions and requires minimal resources. Its cultivation can enhance farm profitability through the integration of summer vegetable production. Lavender (Lavandula spp.), another high-value crop, is well-suited for the region and offers multiple uses in essential oils and personal care products. Rosemary (Rosmarinus officinalis) and thyme (Thymus vulgaris) are also highlighted for their drought tolerance and medicinal properties. Chamomile (Matricaria chamomilla) and Damask rose (Rosa damascena) are noted for their medicinal uses and potential in commercial production. The document underscores the importance of proper soil and water management, organic farming practices, and the role of secondary metabolites in enhancing crop quality under stressful conditions. Intercropping and the use of farm residues for soil conservation are also discussed. The review concludes that these high-value crops can diversify farm income, improve land use efficiency, and offer sustainable agricultural solutions for water-scarce regions in northern New Mexico.

The R2R3-MYB transcription factor PgTT2 from Panax ginseng interacts with the WD40-repeat protein PgTTG1 during the regulation of proanthocyanidin biosynthesis and the response to salt stress

Proanthocyanidins (PAs) are flavonoid compounds with important defensive roles in plants. The application of PAs in industries such as the pharmaceutical industry has led to increased interest in enhancing their biosynthesis. In Arabidopsis thaliana, PAs are biosynthesized under the regulation of an R2R3-MYB transcription factor TRANSPARENT TESTA 2 (TT2), which can interact with other proteins, including TRANSPARENT TESTA GLABRA 1 (TTG1), while also regulating a plant's response to abiotic stressors. However, the regulation of PA biosynthesis in the high-value medicinal plant Panax ginseng (ginseng) has not yet been studied. Understanding the mechanism of PAs biosynthesis regulation in ginseng may be helpful in increasing the plant's range of pharmacological applications. This study found that the overexpression of PgTT2 increased PA biosynthesis by an average of 67.3% in ginseng adventitious roots and 50.5% in arabidopsis seeds. Furthermore, transgenic arabidopsis plants overexpressing PgTT2 produced increased reactive oxygen species (ROS) scavenging ability by influencing abscisic acid synthesis and signaling. However, under high salinity stress, seed germination and growth rate of seedlings were decreased. An expression analysis of plants facing salt stress revealed increased transcripts of an ABA biosynthetic gene, NCED3, and ABA signaling genes ABI5 and ABI3. Moreover, the PgTT2 protein showed a direct interaction with PgTTG1 in yeast two-hybrid assays. This study therefore reveals novel information on the transcriptional regulation of PA production in ginseng and shows how PgTT2 influences the ABA response pathway to regulate responses to ROS and salt stress.

Towards differentiation of Panax vietnamensis and Panax vietnamensis var. fuscidiscus by UPLC-QTOF-MS

Vietnamese ginseng (Panax vietnamensis Ha et Grusvh., Araliaceae - PV) is a high-value medicinal plant of Vietnam. Recently, a new variety of this plant P. vietnamensis var fuscidiscus (PVF), so-called Lai Chau ginseng, was discovered and circulated on the Vietnam market along with PV. PV and PVF rhizomes and roots are preliminarily reported to possess similar saponin composition. However, PV is much more expensive than PVF due to the higher regard of the consumer, which consequently leads to the inattentive misuse or intentional adulteration of PV by PVF. In this study, a UPLC-ToF-MS method was developed to distinguish PV and PVF based on their saponin profiles. The UPLC qualitative result showed that the saponin constituent of PVF is more complex than that of PV. The significant differences in the chromatogram of PV and PVF extracts are the peaks eluted from 32 - 48 min. Vina-ginsenoside R2 (9), chikusetsusaponin L8 (10), and notoginsenoside R4 (12) are characterized for PVF, while notoginsenoside Fa (13), quinquenoside R1 (16), and pseudoginsenoside Rs1 (19) are specialized for PV. The preliminary quantitative determination result showed that the content of majonoside R2, ginsenoside Rg1, ginsenoside Rb1, and ginsenoside Rd in PV is higher than in PVF. In contrast, the content of majonoside R1 and vina-ginsenoside R2 in PVF is significantly higher than in PV. The developed method could be used as an effective method to distinguish PV and PVF.

Assessing the risks to valuable medicinal plants in Nepal from human activities and environmental factors

The demand for trade has led to unsustainable harvesting of medicinal plants, causing a decline in their population in natural habitats. This presents a notable problem, however, there is a lack of information regarding the severity of the threat to these resources. To address this, a study was conducted to identify high-value medicinal plants in the Annapurna Conservation Area in Nepal and evaluate their potential endangerment by using the Rapid Vulnerability Assessment method (RVA). The study also calculated the distribution of these plants in different habitats and their population size. Results showed that there were 19 threatened, high-value medicinal plants in the region frequently used by local communities and with high trade values. Rhizome/roots were the most commonly used plant parts (58%), followed by whole plants (37%). The wild population of these plants was found to be low, with varying abundance among different habitats. Overexploitation driven by high trade demand, low population density, and critical life forms were identified as the main threats to these plants. The study placed Dactylorhiza hatagirea and Neopicrorhiza scrophulariiflora in the highest threat category. Effective conservation and management measures, both in-situ and ex-situ, were suggested based on the population and threat status of these high-value medicinal plants.

Traditional uses, Phytochemistry, Pharmacology, and Toxicology of the Genus Artemisia L. (Asteraceae): A High-value Medicinal Plant.

Biologically active secondary metabolites, essential oils, and volatile compounds derived from medicinal and aromatic plants play a crucial role in promoting human health. Within the large family Asteraceae, the genus Artemisia consists of approximately 500 species. Artemisia species have a rich history in traditional medicine worldwide, offering remedies for a wide range of ailments, such as malaria, jaundice, toothache, gastrointestinal problems, wounds, inflammatory diseases, diarrhoea, menstrual pains, skin disorders, headache, and intestinal parasites. The therapeutic potential of Artemisia species is derived from a multitude of phytoconstituents, including terpenoids, phenols, flavonoids, coumarins, sesquiterpene lactones, lignans, and alkaloids that serve as active pharmaceutical ingredients (API). The remarkable antimalarial, antimicrobial, anthelmintic, antidiabetic, anti-inflammatory, anticancer, antispasmodic, antioxidative and insecticidal properties possessed by the species are attributed to these APIs. Interestingly, several commercially utilized pharmaceutical drugs, including arglabin, artemisinin, artemether, artesunate, santonin, and tarralin have also been derived from different Artemisia species. However, despite the vast medicinal potential, only a limited number of Artemisia species have been exploited commercially. Further, the available literature on traditional and pharmacological uses of Artemisia lacks comprehensive reviews. Therefore, there is an urgent need to bridge the existing knowledge gaps and provide a scientific foundation for future Artemisia research endeavours. It is in this context, the present review aims to provide a comprehensive account of the traditional uses, phytochemistry, documented biological properties and toxicity of all the species of Artemisia and offers useful insights for practitioners and researchers into underutilized species and their potential applications. This review aims to stimulate further exploration, experimentation and collaboration to fully realize the therapeutic potential of Artemisia in augmenting human health and well-being.

Alleviation of Seed Dormancy in Kala Zeera (Bunium Persicum) Through Chilling and Phytohormones

Kala zeera (Bunium persicum) is a high-value medicinal spice plant. The seeds and extracts are used for culinary, perfumery, flavouring food and medicinal purposes. The commercial cultivation of kala zeera is hampered due to poor seed germination and deep physiological dormancy. To break the dormancy of kala zeera, three phytohormones, gibberellic acid (100 μmol L-1), 6-benzylaminopurine (10 μmol L-1) and thidiazuron (6.3 μmol L-1) were tested individually and in combination, under two temperature levels: continuous chilling at 4°C and one week chilling at 4°C followed by incubation at room temperature. The combined application of the three phytohormones under continuous chilling (4°C) improved the germination from 11.25 to 93.25% and reduced the mean germination time 60 to 50 days. The lowest mean germination time (34.78 days) and high mean daily germination (1.57 seeds day-1) with a high coefficient of germination velocity (2.88), were found under combined application of phytohormones as compared to their individual application. The findings have implications in successful propagation and systematic cultivation of this high-value medicinal spice plant.

Genome-Wide Identification of Fatty Acyl-CoA Reductase (FAR) Genes in Dendrobium catenatum and Their Response to Drought Stress

Dendrobium catenatum is a high-value medicinal plant that is predominantly found in high mountain areas, thriving amidst cliffs and rock crevices. However, its wild resources face constant threats from adverse environmental conditions, especially drought stress. Fatty acyl-CoA reductase (FAR) is crucial in plant drought resistance, but there is a lack of research on FAR genes in D. catenatum. In this study, the FAR family genes were identified from the D. catenatum genome. Their genomic characteristics were investigated using bioinformatics techniques, and their expression patterns in different tissues and under 20% PEG8000 conditions mimicking drought stress were analyzed using quantitative real-time RT-PCR (RT-qPCR). Seven DcFAR genes were identified from the D. catenatum genome. The encoded amino acids range between 377 and 587 aa, with molecular weights between 43.41 and 66.15 kD and isoelectric points between 5.55 and 9.02. Based on the phylogenetic relationships, the FAR family genes were categorized into three subgroups, each with similar conserved sequences and gene structures. The cis-acting elements of the promoter regions were assessed, and the results reveal that the DcFAR upstream promoter region contains multiple stress-related elements, suggesting its potential involvement in abiotic stress responses. The RT-qPCR results show distinct expression patterns of DcFAR genes in various plant tissues. It was observed that the expression of most DcFAR genes was upregulated under drought stress. Among them, the expression levels of DcFAR2, DcFAR3, DcFAR5, and DcFAR7 genes under drought stress were 544-, 193-, 183-, and 214-fold higher compared to the control, respectively. These results indicate that DcFAR2/3/5/7 might play significant roles in D. catenatum drought tolerance. This research offers insight into the function of DcFAR genes and provides theoretical support for breeding drought-resistant D. catenatum varieties.

Plants biodiversity utilisation in Bardarash, Kurdistan Region, Iraq

Plants have been used as medicine by humans from the beginning of recorded history. WHO reports that between 65% and 80% of the population in developing nations uses only natural remedies. It should be noted that the research area was selected due to the rich traditional knowledge of its people and the wide range of flora and fauna found there. The goal of these studies is to strengthen local knowledge by compiling a list of valuable plants for traditional medicine. Expert sampling method was utilised in the study with aid of an in-depth interview guide. Fourty two informants were interviewed from the period of September 2021-June 2022. Dominance of men were observed in the study 73.8 %. Age range of 56-65 dominated the study with 38.1%. The current study uncovered 42 plants from 24: Laminaceae (19.2%), Composite (12.8%), Brassica (6.4%), and Leguminosae (6.4%) and the remaining families each (2.1 %). Leaves and fruits are the most frequent used part of the plant at 24.5 % respectively. For the first time, the ethno botanical application of plant species from Bardarash was documented. Illegal collection, trading, and marketing have jeopardized the quantity and distribution of some high-value medicinal plants. The significance of preserving floral diversity is essential.

Heterologous expression of Chlorophytum borivilianum Squalene epoxidase in tobacco modulates stigmasterol production and alters vegetative and reproductive growth.

CbSE overexpression increased stigmasterol levels and altered plant morphology. The genes upstream and downstream of CbSE were found to be upregulated, which confirms its regulatory role in the saponin biosynthetic pathway. Chlorophytum borivilianum is a high-value medicinal plant with many promising preclinical applications that include saponins as a major active ingredient. Squalene epoxidase (SE) is one of the major rate-limiting enzymes of the saponin biosynthetic pathway. Here, we functionally characterized C. borivilianum SE (CbSE) by over-expressing heterologously in Nicotiana tabacum. The heterologous expression of CbSE resulted in stunted pant growth with altered leaf and flower morphology. Next, RT-qPCR analysis of transgenic plants overexpressing CbSE revealed increased expression levels of Cycloartenol synthase (CAS), Beta amyrin synthase (βAS), and cytochrome P450 monooxygenase 51 (CYP51) (Cytochrome P450), which encode key enzymes for triterpenoid and phytosterol biosynthesis in C. borivilianum. Further, Methyl Jasmonate (MeJa) treatment upregulated Squalene synthase (SQS), SE, and Oxidosqualene cyclases (OSCs) to a significant level. GC-MS analysis of the leaf and hairy roots of the transformants showed an increased stigmasterol content (0.5-1.0fold) compared to wild type (WT) plants. These results indicate that CbSE is a rate-limiting gene, which encodes an efficient enzyme responsible for phytosterol and triterpenoid production in C. borivilianum.

Light exposure of roots in aeroponics enhances the accumulation of phytochemicals in aboveground parts of the medicinal plants Artemisia annua and Hypericum perforatum.

Light acts as a trigger to enhance the accumulation of secondary compounds in the aboveground part of plants; however, whether a similar triggering effect occurs in roots is unclear. Using an aeroponic setup, we investigated the effect of long-term exposure of roots to LED lighting of different wavelengths on the growth and phytochemical composition of two high-value medicinal plants, Artemisia annua and Hypericum perforatum. In A. annua, root exposure to white, blue, and red light enhanced the accumulation of artemisinin in the shoots by 2.3-, 2.5-, and 1.9-fold, respectively. In H. perforatum, root exposure to white, blue, red, and green light enhanced the accumulation of coumaroylquinic acid in leaves by 89, 65, 84, and 74%, respectively. Root lighting also increased flavonol concentrations. In contrast to its effects in the shoots, root illumination did not change phytochemical composition in the roots or root exudates. Thus, root illumination induces a systemic response, resulting in modulation of the phytochemical composition in distal tissues remote from the light exposure site.

Distribution of important medicinal plant species in Nepal under past, present, and future climatic conditions

Climate change is causing shifts in the habitat, distribution, ecology, and phenology of Himalayan plants. These changes are predicted to continue, jeopardizing the survival of medicinal plant species and local livelihoods that rely on them. We analyzed the present and future diversity and distribution of medicinal plant species influenced by different climate change scenarios, and calculated the climatic niche of the species using ensemble species distribution modeling (eSDM). We compiled 1041 (N) geospatial data of seven high-value medicinal plant species of Nepal: Aconitum spicatum (n = 100), Allium wallichii (n = 151), Bergenia ciliata (n = 48), Nardostachys jatamansi (n = 121), Neopicrorhiza scrophulariiflora (n = 94), Paris polyphylla (n = 310) and Valeriana jatamansi (n = 217) including over 85 % from field surveys and the rest from literature and online database. We used bioclimatic variables from Models for Interdisciplinary Research on Climate (MIROC) of version MIROC6, and selected Shared Socioeconomic Pathways (SSP)2-4.5 and SSP5-8.5 for the year of 2050 and 2070 for modeling. We found elevation, mean diurnal and annual temperature ranges (BIO2 and BIO7), and precipitation of warmest and coldest quarters (BIO18 and BIO19) to be the most high weight cofactors for projecting the future potential distribution of high-value medicinal plants in Nepal. Results showed that the suitable range of distribution for high-value medicinal plants would increase and concentrate in mountainous areas of central Nepal, but decline in (sub)tropical and temperate areas, suggesting both in-situ and ex-situ conservation practices, respectively.

Investigations of plausible pharmacodynamics supporting the antispasmodic, bronchodilator, and antidiarrheal activities of Berberis lycium Royle. Via in silico, in vitro, and in vivo studies

Ethnopharmacological relevanceBerberis lycium Royle, a member of the Berberidaceae family, is a high-value medicinal plant with a documented history of usage in traditional medicine and has demonstrated significant therapeutic results among local populations throughout the globe. It is used traditionally in many parts of Pakistan to treat diarrhea, abdominal spasms, coughs, and chest problems. Aim of the studyTo investigate the antispasmodic, bronchodilator, and antidiarrheal effects of B. lycium and its possible underlying mechanisms through in silico, in vitro, and in vivo studies. Materials and methodsLC ESI–MS/MS analysis was used to identify bioactive components within the hydromethanolic extract of B. lycium. In silico studies, including network pharmacology and molecular docking, were utilized to investigate the antispasmodic and bronchodilator properties of the extract's bioactive components. In vitro pharmacological studies were conducted using isolated rabbit jejunum, trachea, urinary bladder, and rat ileum preparations. In vivo antidiarrheal activities were conducted in mice, including castor oil-induced diarrhea, intestinal transit, and castor oil-induced enteropooling. ResultsThe LC ESI–MS/MS analysis of the hydromethanolic extract of B. lycium identified 38 bioactive compounds. Network pharmacology study demonstrated that the mechanism of BLR for the treatment of diarrhea might involve IL1B, TLR4, PIK3R1, TNF, PTPRC, IL2, PIK3CD, and ABCB1, whereas, for respiratory ailments, it may involve PIK3CG, TRPV1, STAT3, ICAM1, ACE, PTGER2, PTGS2, TNF, MMP9, NOS2, IL2, CCR5, HRH1, and VDR. Molecular docking research revealed that chlorogenic acid, epigallocatechin, isorhamnetin, quinic acid, gallic acid, camptothecin, formononetin-7-O-glucoside, velutin, caffeic acid, and (S)-luteanine exhibited a higher docking score than dicyclomine with validated proteins of smooth muscle contractions such as CACB2_HUMAN, ACM3_HUMAN, MYLK_HUMAN, and PLCG1_HUMAN. In vitro investigations demonstrated that Blr.Cr, Blr.EtOAc, and Blr.Aq relaxed spontaneously contracting jejunum preparations; carbachol (1 μM)-induced and K+ (80 mM)-induced jejunum, trachea, and urinary bladder contractions in a concentration-dependent manner, similar to dicyclomine. Moreover, Blr.Cr, Blr.EtOAc, and Blr.Aq exhibited a rightward shift in Ca+2 and carbachol cumulative response curves, similar to dicyclomine, demonstrating the coexistence of antimuscarinic and Ca+2 antagonistic mechanisms due to the presence of alkaloids and flavonoids. In vivo antidiarrheal activities showed that the hydromethanolic extract was significantly effective against castor oil-induced diarrhea and castor oil-induced enteropooling, similar to loperamide, and charcoal meal intestinal transit, similar to atropine, in mice at doses of 50, 100, and 200 mg/kg body weight, which supports its traditional use in diarrhea. ConclusionThe dual blocking mechanism of muscarinic receptors and Ca+2 channels behind the smooth muscle relaxing activity reveals the therapeutic relevance of B. lycium in diarrhea, abdominal spasms, coughs, and chest problems.

Polypunctosides E-K: seven new steroidal saponins from Polygonatum punctatum Royle ex Kunth and their nitric oxide production inhibitory activities.

Polygonatum punctatum Royle ex Kunth is a high-value medicinal plant found in old natural forests. A phytochemical study on the roots of this plant led to the isolation of seven new steroidal saponins including four furostans (1-4) and three furospirostans (5-7). Their structures were elucidated as (25R)-26-O-(β-D-glucopyranosyl)-furost-5-ene-3β,17α,22α,26-tetraol 3-O-α-L-arabinopyranosyl-(1 → 2)-β-D-glucopyranosyl-(1 → 4)-β-D-galactopyranoside (1), (25R)-26-O-(β-D-glucopyranosyl)-furost-5-ene-3β,14α,17α,22α,26-pentaol 3-O-α-L-arabinopyranosyl-(1 → 2)-β-D-glucopyranosyl-(1 → 4)-β-D-galactopyranoside (2), (25R)-26-O-(β-D-glucopyranosyl)-furost-5-ene-22α-methoxy-3β,17α,26-triol 3-O-α-L-arabinopyranosyl-(1 → 2)-β-D-glucopyranosyl-(1 → 4)-β-D-galactopyranoside (3), (25R)-26-O-(β-D-glucopyranosyl)-furost-5-ene-22α-methoxy-3β,17α,26-triol 3-O-[α-L-arabinopyranosyl-(1 → 2)-β-D-glucopyranosyl-(1 → 4)]-[acetoxy-(→ 6)]-β-D-galactopyranoside (4), 26-O-(β-D-glucopyranosyl)-14α,17α-dihydroxynuatigenin 3-O-α-L-arabinopyranosyl-(1 → 2)-β-D-glucopyranosyl-(1 → 4)-β-D-galactopyranoside (5), 26-O-(β-D-glucopyranosyl)-17α-hydroxynuatigenin 3-O-α-L-arabinopyranosyl-(1 → 2)-β-D-glucopyranosyl-(1 → 4)-β-D-galactopyranoside (6), and 26-O-(β-D-glucopyranosyl)-14α-hydroxynuatigenin 3-O-α-L-arabinopyranosyl-(1 → 2)-β-D-glucopyranosyl-(1 → 4)-β-D-galactopyranoside (7) by extensive spectroscopic analyses, including infrared, high-resolution electrospray ionization mass spectrometry, and one- and two-dimensional nuclear magnetic resonance spectroscopy. Compounds 1-7 inhibited nitric oxide production in lipopolysaccharide activated RAW264.7 cells with IC50 values ranging from 41.5 ± 3.2 to 62.2 ± 3.7µM, compared to 33.8 ± 2.6µM for the positive control compound L-NMMA.

(1) Background: Curcuma caesia Roxb. is a high valued crop which is extensively used in pharmaceuticals, flavour and fragrances. C. caesia is recognised as an endangered species due to its extensive collection from the wild through human intervention. Therefore, to prevent the species from extinction, it is very necessary to conserve and cultivate this plant species for the sustainable availability of the raw material. (2) Methods: In the present plant breeding programme, a multi-year study was performed for the identification of superior genotypes which will help in conservation. To fulfil this objective, a total of 135 accessions of C. caesia were collected from different regions of India and were set up for experimental selection trial for three years (2016–2018). After proper evaluation of the genotypes based on six agronomical traits, five high-yielding genotypes were identified which underwent multilocation trial for two years (2019 and 2020). The stability analysis using the Eberhart–Russell method, AMMI and GGE biplot were used to study the consistency of the genotypes in varied environments compared with the check variety. (3) Results: Analysis of variance indicated significant genotype and environment interaction for the yield traits, i.e., dry rhizome recovery, rhizome yield and essential oil yield. The coefficient of variation (CV) was highest for tillers per plant (21.76) and lowest for the plant height (4.93). All the results clearly demonstrated Jor Lab KH-2 as the highest yielding and stable genotype in varied environments compared with the check variety and other selected genotypes. (4) Conclusions: This genotype was then submitted to ICAR-NBPGR, New Delhi, for germplasm registration and received its confirmation vide registration number INGR 21159. This genotype will greatly benefit the breeders and will also help in the conservation of this endangered species. This is the first report on the identification and registration of a high-yielding variety of C. caesia.

GC MS Based Comparative Phytochemical Profiling of Rhodiola Imbricata Roots Collected from Different High Mountain Passes of Ladakh India and a First Report of Apocynin from Genus Rhodiola

Rhodiola imbricata is a high value medicinal plant of trans-Himalayan mountain passes in Ladakh. This plant is a highly sought after in national and international herbal product market due to its unique phytochemical composition and resultant medicinal properties. However, compositional variation in the raw material from different geographical locations results in variation in quality as well as efficacy of the final products. The current study was designed to generate the comparative GC-MS profiles of hydro-methanolic extracts of Rhodiola imbricata root samples collected from various locations in Ladakh i.e., Chang La (17605 ft), Khardung La (18,379 ft), and Shashi La (13908 ft) mountain passes. The study highlighted variations in volatile phytochemical composition in root samples collected from different locations, especially with respect to phenols, terpenes and fatty acids. Samples from Chang La had maximum amount of phenolic compounds (96.78 per cent), followed by samples from Khardung La (77.05 per cent) while they were undetected in samples from Shashi La pass. Specifically, comparative GC-MS profiling revealed that peak area percentage of two important bioactive compounds (i.e. piceol and apocynin) varied amongst samples. In the samples collected from Chang La, the piceol covered (94 per cent) and apocynin covered (2.78 per cent) peak area whereas in samples collected from Khardung La, piceol covered (73.8 per cent) and apocynin covered (3.25 per cent) peak areas respectively, however, samples collected from Shashi La showed none of these compounds. Interestingly, in the present study, apocynin (a potent NADPH oxidase inhibitor) is being reported for the first time from Rhodoila genus. On the basis of present findings, samples collected from Chang La and Khardung La passes showed better phytochemical composition of pharmacological active phenolic compounds than Shashi La sample.

Genetic diversity and relationships among Glaucium (Papaveraceae) species by ISSR Markers: A high value medicinal plant

Glaucium Mill. (horned poppy), belonging to the family Papaveraceae, is represented by a total of 25 species worldwide, and especially distributed throughout Western, Northern and Eastern Asia, Europe, Northern Africa, and Australia. As a country, Iran harbors relatively more species of the genus Glaucium (11-13 species) and hence, this country is considered as the hot spot of the genus. As a result, we conducted a molecular analysis of the data for this genus due to the relevance of these species of plants. We employed 75 plants from seven species and seven provinces that were randomly picked for this investigation. Five primers were used to amplify genomic DNA, yielding 78 bands, 73 of which were polymorphic (97.78%). ISSR primers have a great capability to recognise polymorphic loci among Glaucium species, as evidenced by the high average PIC and MI values obtained. The genetic similarity of seven samples was calculated to be between 0.77 and 0.92. Glaucium corniculatum var. corniculatum and Glaucium elegans var. elegans showed the lowest similarity, while Glaucium oxylobum and Glaucium grandiflorum had the highest similarity, according to Inter-Simple sequence repeats (ISSR) markers analysis. The following are the study’s goals: 1) Is it possible to identify Glaucium species using ISSR markers? 2) In Iran, how are these taxa genetically structured? 3) what is the inter-species relationship? According to this study, ISSR markers can be utilized to distinguish species.

Floristic diversity in Cold Desert regions of Uttarakhand Himalaya, India

Cold desert regions of Uttarakhand are one of the least explored remote ecosystems in the Himalaya with fragmented database. To address the issue, the task of documenting the floristic diversity of cold deserts of Uttarakhand was taken up in the present study. A total of 932 taxa (908 species, 05 subspecies and 19 varieties) belonging to 371 genera and 76 families of angiosperms and gymnosperms were recorded. In view of conservation of plant diversity, methods such as in-situ conservation, popularizing cultivation of endemic, threatened and high value medicinal plants and controlling the livestock grazing can be adopted.
