The test strains Bacteroidetes bacterium (Ba), Pseudomonas fluorescens (Pf) and Variovorax sp. (Va) were selected in advance for their vitro capability growth promotion of rapeseed the presence increased concentrations Cd, Cu, Pb Zn medium. In pot experiment, used single Ba, Pf, Va or combined Ba + Va, Pf inoculation B. napus growing contaminated soil from alluvial deposits. positive effect bacterial on plant was observed vitro, but not confirmed situ soil, where tested inhibited biomass...

Abstract Drought is one of the major threats to food security. Among several mechanisms involved in plant stress tolerance, protein family—the metallothioneins (MTs)—shows great promise for enhancing drought resistance. Plant oat ( Avena sativa L.) have not yet been deeply analysed, and literature lacks a comprehensive study whole family MTs response drought. In this study, we showed that number nature cis -elements linked with promoters AsMTs1–3 differed depending on MT type. plants caused...

Single and joint ectomycorrhizal (+ Hebeloma mesophaeum) bacterial Bacillus cereus) inoculations of willows (Salix viminalis) were investigated for their potential mode action in the promotion cadmium (Cd) zinc (Zn) phytoextraction. Dual fungal promoted biomass production contaminated soil. either had no effect on plant growth or inhibited it. All inoculated showed increased concentrations nutritional elements (N, P, K Zn) decreased Cd shoots. The lowest concentration B. combined with...

Understanding the impact of drought stress on Arabica coffee physiology and metabolism is essential in pursuit developing drought-resistant varieties. In this study, we explored physiological metabolite changes genotypes exhibiting varying degrees tolerance to drought-namely, relatively tolerant Ca74110 Ca74112, sensitive Ca754 CaJ-19 genotypes-under well-watered conditions during terminal periods at two time points (0 60 days following onset stress). The profiling uncovered significant...

Progressive climate change increases drought frequency, severely impacting crop growth and yield. New eco-friendly alternatives to chemical protection agents fertilisers are needed reduce pollution enhance plant health. This study evaluated the effects of growth-promoting rhizobacteria (PGPR) hydrogel (potassium polyacrylate) on Brassica napus L. during conditions. After in vitro pot experiments, Serratia plymuthica was selected from six PGPR candidates based its ability biomass, shoot...

Background/Objectives: Plant metallothioneins (MTs) are low-molecular-weight proteins involved in heavy metal binding and response to stress conditions. This work aimed analyse canola (Brassica napus L.) MTs (BnMT1-4) salinity plant interaction with bacteria. Methods: (1) We tested germination growth development the presence of sodium chloride bacteria Serratia plymuthica; (2) analysed phytohormones content using LC-MS/MS; (3) identified silico cis-regulatory elements promoters BnMT1-4...

ABSTRACT Food security is defined as uninterrupted access to food that meets people's dietary needs. One essential trace element of a complete diet zinc, which vital for various processes, including growth, development, and the immune response. The estimated global prevalence zinc deficiency around 30%. Meat meat products provide an abundant also bioavailable source zinc. However, in developing countries, restricted, developed consumption has declined ethical environmental reasons. potential...

Forest biomass is a renewable source of environmentally friendly material—wood. However, wood processing generates large amounts by-products, including branches. These byproducts are often used as firewood; however, they can be much more effectively. In this study, the pyrolysis two woods, namely birch and pine, was proposed. The liquid products were studied by FTIR spectroscopy, heating value these evaluated. order to find optimal temperature from point view calorific product, process...

Background To ensure food security in the face of climate change and growing world population, multi-pronged measures should be taken. One promising approach uses plant growth-promoting fungi (PGPF), such as Trichoderma , to reduce usage agrochemicals increase yield, stress tolerance, nutritional value. However, large-scale applications PGPF have been hampered by several constraints, and, consequently, on a large scale is still limited. Seed coating, process that consists covering seeds with...

Salicornia europaea is among the most salt-tolerant of plants, and widely distributed in non-tropical regions. Here, we investigated whether maternal habitats can influence different responses physiology anatomy depending on environmental conditions. We studied habitat S. cell anatomy, pectin content, biochemical enzymatic modifications under six salinity treatments a natural-high-saline (~ 1000 mM) (Ciechocinek [Cie]) an anthropogenic-lower-saline 550 (Inowrocław [Inw]). The Inw population...

In this work, we present the results of inoculation canola seeds (Brassica napus L.) with Trichoderma viride strains that promote growth plants. Seven morphologically different T. (TvI-VII) were shown to be capable synthesizing auxins and exhibited cellulolytic pectinolytic activities. To gain a deeper insight into molecular mechanisms underlying canola-T. interactions, analyzed stress genes metallothioneins (BnMT1-3) stringent response (BnRSH1-3 BnCRSH). We demonstrated presence...

Metallothioneins (MTs) are a family of small proteins rich in cysteine residues. The sulfhydryl group metallothioneins can bind to metal ions, maintaining homeostasis and protecting the cells from damage caused by toxic heavy metals. Moreover, MTs function as reactive oxygen species scavengers since thiols undergo reversible irreversible oxidation. Here, we identified 21 metallothionein genes (AsMTs) oat (Avena sativa L.) genome, which were divided into four types depending on amino acid...

The problem of handling zinc in the cell is great importance because an indispensable micronutrient involved most physiological processes all living organisms. Moreover, our understanding mechanisms governing discrimination between micronutrients and toxic metals on level individual proteins to whole-organism incomplete. Metallothioneins are able bind heavy metal ions, roles homeostasis have been proposed. Here, we studied vitro vivo metal-binding abilities Brassica napus type 4...

Plastic pollution is one of the crucial global challenges nowadays, and biodegradation a promising approach to manage plastic waste in an environment-friendly cost-effective way. In this study we identified strain fungus Trichoderma viride GZ1, which was characterized by particularly high pectinolytic activity. Using differential scanning calorimetry, Fourier-transform infrared spectroscopy techniques, viscosity measurements showed that three-month incubation polylactide polyethylene...
