Biostimulant effect of Cladophora glomerata extract on garden cress plant growth

Biostimulants that improve agriculture's productivity and environmental responsibility are widely favored and used. Algae has emerged as a viable option for sustainable agriculture. In the present study, the effects of the Cladophora glomerata (L.) Kütz. aqueous extract in three concentrations (2.5, 5, and 10 mg extract per mL of tap water) was tested on the growth and productivity of garden cress (GCR) Lepidium sativum L., plants over 12 days, and the results were compared with those of the control group (irrigated only with tap water). The effect of the algae extract was studied by assessing the changes in phenolic compounds using HPLC–DAD and determining the chlorophyll content as well as the total antioxidant capacity of the GCR using DPPH and ABTS tests. Total phenolics, as well as total flavonoids, were measured. The potential role of algae extract in promoting cress plant growth was attained when compared to the control, mainly at a concentration of 2.5 mg/mL, which exhibited the highest yield growth after 12 days and presented the highest antioxidant capacity at 13.53 ± 1.16 mg Trolox equivalent (TE)/g dry weight (DW), compared to 10.44 ± 0.33 mgTE/g DW for the control. The total phenolic content significantly increased (p < 0.05) from 14.34 ± 0.84 mg gallic acid equivalent (GAE)/ g dry weight (DW) to 23.14 ± 0.55 mg GAE/g DW. Eleven phenolic compounds were identified in different tested samples of GCR, whether treated or not treated with algae extracts. Chrysin was only identified in the treated plants. Therefore, the use of algae (C. glomerata) presents promising potential as a biostimulant in agriculture, contributing to increased plant growth and improved resistance to environmental stress.

CHARACTERIZATION OF SYNTHESIZED SILVER NANOPARTICLES USING LEPIDIUM SATIVUM PLANT

The biosynthesis of Silver Nanoparticles (Ag NPs) was achieved through the utilization of an extract derived from the plant Lepidium Sativum, commonly referred to as Garden cress. The current study was undertaken to examine the impacts of different concentrations of silver nitrate (AgNO3) (0.1, 0.15, 0.2, 0.25, and 0.3) on the properties of silver nanoparticles. A range of analytical techniques were utilized to examine the characteristics of the nanoparticles, encompassing energy dispersive X-ray (EDX), field emission scanning electron microscopy (FESEM), UV-visible spectrophotometry (UV-Vis), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR). The findings demonstrated and suggested that Lepidium Sativum represents a viable choice for the environmentally friendly production of silver nanoparticles. The UV-Vis spectra of the studied silver nanoparticles (Ag NPs) exhibited a significant level of absorption within the wavelength range of 430-460 nm. The most intense absorption peak, observed at 453 nm, was associated with a concentration of 0.25 mol. The examination of the Field Emission Scanning Electron Microscope (FESEM) images has revealed that the concentration of the solution has a substantial impact on the size, morphology, shape, and orientation of the silver nanoparticles (Ag NPs). The Ag NPs exhibit a mostly spherical and semi-spherical form, with an average particle size ranging from 65 to 80 nm. Additionally, the X-ray diffraction (XRD) analysis revealed that the silver nanoparticles (Ag NPs) synthesized exhibit a high level of purity, consisting solely of silver atoms arranged in a face-centered cubic crystalline lattice structure. The particle size, as determined from the (111) peak, falls within the range of 25.31-67.28 nm. The EDX spectrum analysis indicated that the primary chemical constituent present in the samples was silver (Ag). The silver nanoparticles (Ag NPs) produced at different concentrations exhibited a distinct peak in the UV-Vis spectrum, demonstrating significant absorbance above 400 nm in the visible region and minimal absorption in the UV range. The measured energy band gap (Eg) ranged from 2.05 to 2.3 eV. In addition, the Fourier Transform Infrared (FTIR) spectra of silver nanoparticles (Ag NPs) at different concentrations did not exhibit any discernible peak throughout the monitored range. This observation implies that the silver nanoparticles that were produced using cress plant extract had a high level of purity.

Determination of the effect of soil and irrigation water quality on total chlorophyll, carbohydrates, and proteins values in cress, parsley, celery, and basil plants.

The effect of soil and irrigation water quality in three sites of the Khasah Su River basin Kirkuk-Iraq was studied on the values ​​of total chlorophyll, carbohydrates, and proteins of cress, parsley, celery, and basil plants. Samples were collected from November 2021 to May 2022. Sampling sites in the Khasah Su River located between longitudes 44o 23/ and 44o 24/ and latitudes 35o 24/ and 35o 29/. Soil quality index (SQI) values ​​documented poor soil fertility in all sites, especially on the third site. Irrigation water quality index (IWQI) values were excellent in the first site, good in the second site, and poor in the third site. The basil plant recorded the lowest mean values ​​of carbohydrates 0.59ppm in the first site and proteins 0.26ppm in the second site and the cress plant recorded the lowest mean value of total chlorophyll at 7.92ppm in the first site. Parsley plant recorded the highest mean values ​​of carbohydrates 5.69ppm and total chlorophyll 21.46ppm, and cress plant highest average values ​​of proteins 1.63ppm on the third site. Basil and cress plants were the most affected by the decrease in soil quality and irrigation water index at the study sites, while parsley and celery plants were the least affected.

Investigation of different lighting (LED, HPS and FLO) in aquaponics systems for joint production of different plants (Lettuce, Parsley and Cress) and koi carp

We investigated the effects of growth performance of three plant species parsley (Petroselinum crispum), lettuce (Lactuca sativa) and cress (Lepidium sativum) under the three different lighting sources, Light-Emitting Diode lamp (LED; 200w), High-Pressure Sodium lamp (HPS; 200w) and Fluorescent lamp (FLO; 200w) in an aquaponic system. A total number of 43 koi fish (Cyprinus carpio var. koi) with 3628 g total biomass (84.4 g per individual) were used. The fish used in the experiment recorded 36% growth and reached an average individual weight of 132.7 g at the end of the experiment. The parsley plant was measured as 8.76 ±7.32 g; 7.45 ±4.13 g; 2.04 ±1.96 g weight after 45 days, the lettuce plant was 54.09 ± 25.60 g; 60.83 ±19.39 g; 17.81 ±6.40 g weight after 54 days, cress plant was 1.03 ±0.58 g; 1.15 ±0.46 g; 1.31 ±0.58 g weight after 42 days, under the HPS, LED, and FLO light sources, respectively. HPS and LED light sources in lettuce and parsley showed better plant development than the FLO, while no significant difference occurred in cress plants under three light conditions. We conclude that using HPS or LED lights in indoor aquaponics has the potential to produce good quality and adequate amounts of plants.

The Quality and Germination Rate of Seeds Obtained From Garden Cress Grown Under Water Stress

The objective of this study is to determine the sustainability of seeds obtained from plants subjected to water stress. For this reason, seed quality and germination rates were determined in the seeds obtained from the garden cress plant (Lepidium sativum L.) grown under water stress in both laboratory and greenhouse conditions. In the study, apart from the seeds obtained from the 100% irrigated control plants, seeds from the garden cress irrigated with 50% and 25% water were used. The 1000-grain weight of the garden cress seeds, an indicator of seed quality, varied between 1.975-2.227 g in greenhouse conditions and between 2.121-2.248 g in laboratory conditions, where the changes in both conditions were statistically significant. The germination rates of the garden cress seeds grown under different water stress levels were found to be between 97-99% in greenhouse conditions. It was determined that in laboratory conditions all test subjects had a 100% germination rate. As a result, it was concluded that the seeds obtained from the garden cress plant, which was exposed to water stress during their growing period, continued their vitality despite water stress.

Combined Effects of Phosphate Solubilizing Bacteria and Nanosilica on the Growth of Land Cress Plant

The present study was done to isolate and characterize two strains of phosphate solubilizing bacteria from rhizospheres of acacia, sugar beet, and wheat, then determine synergic effects of nanosilica and these strains on the vegetative growth of land cress plant. Isolates identification was performed using physiological, morphological, biochemical tests, and 16S ribosomal ribonucleic acid sequencing. Nanosilica was extracted from Equisetum telmateia and characterized via X-ray diffraction, scanning electron microscopy, dynamic light scattering, Brunauer–Emmett–Teller, and X-ray fluorescence techniques. The size and the purity of extracted silica powder were about 30 nm, 97.5 %, respectively. Two strains, namely, Pseudomonas stutzeri and Mesorhizobium sp. were the most efficient strains to grow and solubilize phosphorus in the presence of 860 mM NaCl and various pH conditions. The highest growth of these two strains was observed at 0.05 and 0.07 ppm of nanosilica. The highest amount of dry weight of shoot and root of land cress plant was recorded with the simultaneous application of these strains in combination with nanosilica. The combination of nanosilica and these strains enhanced the soil nitrogen and phosphorus content and the vegetative growth of land cress plant.

Contribution of Eutrema salsugineum Cold Shock Domain Structure to the Interaction with RNA.

Plant cold shock domain proteins (CSDPs) are DNA/RNA-binding proteins. CSDPs contain the conserved cold shock domain (CSD) in the N-terminal part and a varying number of the CCHC-type zinc finger (ZnF) motifs alternating with glycine-rich regions in the C-terminus. CSDPs exhibit RNA chaperone and RNA-melting activities due to their nonspecific interaction with RNA. At the same time, there are reasons to believe that CSDPs also interact with specific RNA targets. In the present study, we used three recombinant CSDPs from the saltwater cress plant (Eutrema salsugineum) - EsCSDP1, EsCSDP2, EsCSDP3 with 6, 2, and 7 ZnF motifs, respectively, and showed that their nonspecific interaction with RNA is determined by their C-terminal fragments. All three proteins exhibited high affinity to the single-stranded regions over four nucleotides long within RNA oligonucleotides. The presence of guanine in the single- or double-stranded regions was crucial for the interaction with CSDPs. Complementation test using E. coli BX04 cells lacking four cold shock protein genes (ΔcspA, ΔcspB, ΔcspE, ΔcspG) revealed that the specific binding of plant CSDPs with RNA is determined by CSD.

The athlete as model organism: The everyday practice of the science of human performance

Behind every champion athlete are scores of physiologists studying his or her performance. This is no new phenomenon. Since the late 19th century, physiologists have been bringing ‘well-trained’ athletes into their labs to produce knowledge about how human bodies work, to determine the causes of human fatigue, and to probe human limits. In this article, I argue that the athlete, like the fruit fly or the mouse cress plant, can be considered a model organism. Ethnographic data are presented from 7 months of participant-observation and semistructured interviews in three human performance laboratories located in South Africa, the United Kingdom, and the United States. Ethnographic data suggest that the athlete functions as a model organism in physiology for two reasons. First, athletes ‘accommodate’ the particular experimental instruments and practical demands of fatigue research. Second, a distinct ‘biosociality’ drives the choice of athlete as model organism.

Studying of the Nitrate Contamination in Garden Cress Plant in Dezful, Khouzestan, Iran

In recent years, there has been much attention to the amount of nitrate. Nitrate is not toxic for animals and human. However, if nitrate reduces to nitrite, it can combine with hemoglobin and form met-hemoglobin. Regarding the importance of this subject, they present research was conducted to study the situation of Garden cress in terms of nitrate contamination in vegetable farms in Dezful city. Samples after being shaking, the extract was separated by centrifuge and nitro Sulfusalicylic complex. Then it was read by spectrophotometer in wave length 410 nm in front of standard solution. Results of analyses indicated that the highest amount of nitrate was seen in the north farm samples of Dezful. Results of statistical analysis revealed significant difference between nitrate amounts in areas under study. Moreover, nitrate concentration was reported less than permitted in Garedn cress. As well, nitrate concentration tested in the morning and afternoon samples showed significant difference and the highest difference was related to north of Dezful. Therefore, in order to obtain low levels of nitrate concentration, considering soil Analysis, organic cultivation, consuming organic and biologic fertilizers, micronutrients and eugenics can be regarded.

Evaluation on Application of Artificial Soil Made by Organic Wastes

Natural soil would be used for planting on paved area ground, but it had been replaced by the light weighted artificial soil to minimize burden of the structure. But, the existing light weighted soil had nearly capacity of fertilizer adsorption due to its glassy surface. In this study, the artificial soil prepared by sewage sludge was manufactured, tested characteristics as soil and examined on planting. The developed soil was analyzed through specific gravity, pH, water content, volatile matter and was tested on adsorption capacity of Cu. In addition, planting examination analyzed the leaf growth of planting and mouseear cress plant's pollen. As the result, the developed artificial soil showed to be color yellowish brown, bulk density 0.6g/cm3, pH 8~9, volatile matter 0.3, CEC 10, pressure strength 25 ton/m2, hydrophilic and non-toxic, which was suitable for rooftop gardening. Also, periodic growth rate and development of leaves was satisfactory as natural soil and growth and numbers of pollens were good. Consequently, the developed artificial soil with porosity and capacity of fertilizer adsorption could be usefully applicable to planting on the paved area.

Construction of a Plant Transformation‐ready Expression cDNA Library for Thellungiella halophila Using Recombination Cloning

Abstract Salt cress (Thellungiella halophila), a close relative of the model plant Arabidopsis thaliana L., is an extremophile that is adapted to harsh saline environments. To mine salt‐tolerance genes from this species, we constructed an entry cDNA library from the salt cress plant treated with salt‐stress by using a modified cDNA synthesis and an improved recombination‐assisted cDNA library construction method that is completely free of manipulations involving restriction enzymes and DNA ligase. This cDNA library construction procedure is significantly simplified and the quality of the cDNA library is improved. This entry cDNA library was subsequently shuttled into the destination binary vector pCB406 designed for plant transformation and expression via recombination‐assisted cloning. The library is plant transformation ready and is used to transform Arabidopsis on a large scale in order to create a large collection of transgenic lines for functional gene mining.

In silico characterization of the family of PARP-like poly(ADP-ribosyl)transferases (pARTs).

BackgroundADP-ribosylation is an enzyme-catalyzed posttranslational protein modification in which mono(ADP-ribosyl)transferases (mARTs) and poly(ADP-ribosyl)transferases (pARTs) transfer the ADP-ribose moiety from NAD onto specific amino acid side chains and/or ADP-ribose units on target proteins.ResultsUsing a combination of database search tools we identified the genes encoding recognizable pART domains in the public genome databases. In humans, the pART family encompasses 17 members. For 16 of these genes, an orthologue exists also in the mouse, rat, and pufferfish. Based on the degree of amino acid sequence similarity in the catalytic domain, conserved intron positions, and fused protein domains, pARTs can be divided into five major subgroups. All six members of groups 1 and 2 contain the H-Y-E trias of amino acid residues found also in the active sites of Diphtheria toxin and Pseudomonas exotoxin A, while the eleven members of groups 3 – 5 carry variations of this motif. The pART catalytic domain is found associated in Lego-like fashion with a variety of domains, including nucleic acid-binding, protein-protein interaction, and ubiquitylation domains. Some of these domain associations appear to be very ancient since they are observed also in insects, fungi, amoebae, and plants. The recently completed genome of the pufferfish T. nigroviridis contains recognizable orthologues for all pARTs except for pART7. The nearly completed albeit still fragmentary chicken genome contains recognizable orthologues for twelve pARTs. Simpler eucaryotes generally contain fewer pARTs: two in the fly D. melanogaster, three each in the mosquito A. gambiae, the nematode C. elegans, and the ascomycete microfungus G. zeae, six in the amoeba E. histolytica, nine in the slime mold D. discoideum, and ten in the cress plant A. thaliana. GenBank contains two pART homologues from the large double stranded DNA viruses Chilo iridescent virus and Bacteriophage Aeh1 and only a single entry (from V. cholerae) showing recognizable homology to the pART-like catalytic domains of Diphtheria toxin and Pseudomonas exotoxin A.ConclusionThe pART family, which encompasses 17 members in the human and 16 members in the mouse, can be divided into five subgroups on the basis of sequence similarity, phylogeny, conserved intron positions, and patterns of genetically fused protein domains.
