Characterization and isolation of 1-aminocyclopropane1-carboxylate (ACC) deaminase-producing, plant growth-promoting rhizobacteria from the rhizosphere of Egyptian wheat cultivars for improved drought resilience.

Drought stress severely damages the growth and development of wheat and leads to lower crop production. The application of plant growth-promoting rhizobacteria (PGPR) is a sustainable approach that enhances plant tolerance to drought. This study investigated whether different bacterial isolates could promote wheat growth under drought conditions.
