Potassium is an essential nutrient that influences key processes in plants, including osmotic regulation, photosynthesis, and nitrogen assimilation. This study investigated the drought tolerance of wheat (Triticum spp.) plants treated with sufficient potassium (SK, 1 mM) low (LK, 0.05 under PEG-induced stress. Plant physiological development, canopy temperature, photosynthetic efficiency, antioxidant defense enzymes, assimilation enzymes were assessed. In non-drought conditions, LK increased temperature reduced dry matter yield performance, these effects becoming more pronounced SK-treated exhibited higher biomass, chlorophyll content, maximum quantum efficiency photosystem II, lower temperatures, even conditions. Furthermore, restricted accumulation regulators, proline, amino acids, soluble sugars. Under stress, also showed hydrogen peroxide superoxide anion levels, while SK had reactive oxygen species enzyme activities (catalase dismutase). Additionally, resulted activity (nitrate reductase, NR, nitrite NiR) both normal contrast, seedlings maintained NR NiR protein content during These findings underscore critical role management enhancing yield, particularly water-scarce regions, as optimal supply strengthens biochemical mechanisms improve plant to

Endophytic microbial communities have essential information for scientists based on their biological contribution to agricultural practices. In the external plant environment, biotic and abiotic factors affect populations before getting into tissues. Endophytes are involved in mutualistic antagonistic activities with host plant. Microbial inhabiting internal tissues of roots depend ability live contend other microflora. The advantageous ones contribute soil health growth either directly or indirectly. move via soil-root environment endosphere plants promoting features like antibiosis, induced systemic resistance, phytohormone synthesis, bioremediation. Therefore, existence these microorganisms contributes genomes, nutrient availability soil, presence pathogens, factors.

Maize is a crucial staple crop that ensures global food security by supplying essential nutrients. However, heavy metal (HM) contamination inhibits maize growth, reduces output, and affects security. Some endophytic fungi (EFs) in seeds have the potential to enhance growth increase dry biomass, offering solution mitigate negative effect of HM contamination. Using these functional EFs could help maintain production ensure safety HM-contaminated areas. In present study, diversity corn grains from various areas China was studied through culture-dependent culture-independent methods. We tested plant growth-promoting (PGP) traits several dominant culturable isolates evaluated effects twenty-one pot experiments. Both studies showed increased richness grain affected most endophytes. Nigrospora Fusarium were prevalent endophytes Conversely, Cladosporium spp. isolated non-contaminated Different this, Saccharomycopsis sites, while Neofusicoccum Sarocladium according analysis. PGP trait tests indicated 70% (forty-two) exhibited phosphorus solubilization, IAA production, or siderophore activity. Specifically, 90% sites better results than 45% sites. The benefit on host further experiments, which all improve growth. Among them, strains derived including AK18 (Nigrospora), AK32 (Beauveria), SD93 (Gibberellia), SD64 (Fusarium), had notable enhancing biomass shoots roots under Cd stress. speculate higher ratio may explain their competitiveness such extreme environments. show high properties, but they can also be phytopathogenic.
