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

The escalating global food demand driven by a gradually expanding human population necessitates strategies to improve agricultural productivity favorably and mitigate crop yield loss caused various stressors (biotic abiotic). Biotic stresses are phytopathogens, pests, nematodes, along with abiotic like salt, heat, drought, heavy metals, which pose serious risks security productivity. Presently, the traditional methods relying on synthetic chemicals have led ecological damage through unintended impacts non-target organisms emergence of microbes that resistant them. Therefore, addressing these challenges is essential for economic, environmental, public health concerns. present review supports sustainable alternatives, emphasizing possible application fungal endophytes as innovative eco-friendly tools in plant stress management. Fungal demonstrate capabilities managing plants against biotic via direct or indirect enhancement plants’ innate immunity. Moreover, they contribute elevated photosynthesis rates, stimulate growth, facilitate nutrient mineralization, produce bioactive compounds, hormones, enzymes, ultimately improving overall resistance. In conclusion, harnessing potentiality represents promising approach toward sustainability practices, offering effective alternative solutions reduce reliance chemical treatments address posed stresses. This ensures long-term promotes environmental economic viability agriculture.

Medicinal plants remain a valuable source for natural drug bioprospecting owing to their multi-target spectrum. However, use as raw materials novel synthesis has been greatly limited by unsustainable harvesting leading decimation of wild populations coupled with inherent low concentrations constituent secondary metabolites per unit mass. Thus, adding value the medicinal research dynamics calls adequate attention. In light this, harbour endophytes which are believed be contributing towards host plant survival and bioactive through series physiological interference. Stimulating metabolite production in using growth regulators demonstrated one most effective methods increasing syntheses. Use promotors could help ensure continuous supply plants, mitigate issues fear extinction. Endophytes minimize heavy metal toxicity plants. It hypothesized that when exposed harsh conditions, associated primary signalling channels induce defensive reactions. go different biochemical processes lead activation defence mechanisms signal transduction pathways, endophytic microorganisms influence genes involved generation cells. Additionally, elucidating role gene clusters expose factors Promising endophyte strains can manipulated enhanced metabolites, hence, better probability strain improvement, mutagenesis, co-cultivation, media adjustment.

In recent years, the importance of microorganisms for plant survival has been increasingly recognized. Endophytic fungi, as part holobiont, can confer growth advantages to plants. Most studies have shown that endophytic fungi forest trees promote host growth, increase adversity resistance, and thus improve competitiveness trees. However, beneficial examples on development woody plants not systematically summarized. This review is focused various aspects in (definition, classification, colonization mechanisms, etc.), with an emphasis their roles protection against biotic abiotic stresses, well response fungi. addition, this lists a series experiments screening from Chinese fir (
