Transcriptomic, biochemical, and microbiome assessments into drought and salinity tolerance in durum wheat mediated by plant growth-promoting bacteria.

ABSTRACT: This study investigates the efficacy of plant growth-promoting bacteria (PGPB) in improving stress tolerance in plants by analyzing the molecular and biochemical bases in durum wheat grain. An experiment was conducted where soil and seeds were inoculated with PGPB, under drought and salinity stress. 16 S rRNA sequencing indicated no change in grain bacterial communities in response to biofertilizers and stress. However, a genome-wide analysis identified 153 up-regulated and 33 down-regulated plant genes in response to PGPB, predominantly enriched in stress-related biological processes. These genes specifically encode for proteins involved in metabolite interconversion enzyme, chaperone, protein modifying enzyme, and transporters, which are functionally related groups assisting protein fold
