ABSTRACT

Biotic and abiotic stresses are key restrictions in agricultural yield, food

grade, and universal food stability. Numerous characteristics are influenced

by stress, including physiological, biochemical, and molecular plant condi­

tions. Soil fertility and environmental contamination have both declined as

a result of the usage of inorganic fertilizers and pesticides in agricultural

practices. As a result, it is critical to construct more secure and long-term

agricultural development methods. Plant growth-stimulating microorgan­

isms (PGPM) and mycorrhizal fungi are used to boost plant growth in these

situations. It offers a cost-effective and environmentally friendly way to

protect plants from stress. Plant growth can be aided by PGPM, which regu­

lates plant hormones, improves nutrient acquisition, generates siderophores,

and improves antioxidant techniques and systems. Acquired systemic resis­

tance (ASR) along with mediated systemic resistance (MSR) are useful in

combating biotic stress (ISR). In stressed conditions, arbuscular mycorrhiza

(AM) improves nutrient and water transportation while also increasing stress
