Significance of inoculation with Bacillus subtilis to alleviate drought stress in wheat (Triticum aestivum L.)


Abstract:

In the present study, ten morphologically distinct indigenous plant growth-promoting rhizobacteria (PGPR) from wheat roots and rhizosphere were screened for multiple plant growth promoting (PGP) traits and out of ten, two strains (SIR1 and KUR2) possessing maximum PGP traits along with ACC (1-aminocyclopropane-1-carboxylic acid) deaminase activity were evaluated at three water stress regimes in wheat: (i) 80% field capacity (FC), (ii) 60% FC, (iii) 40% FC for 45 days, starting from 15 days after sowing to the maturity. Inoculation of SIR1 strain with wheat at 80% FC, induced a significant increase in plant biomass (root biomass, 66.67%; shoot biomass, 39.09%) together with decreased reactive oxygen species and increased activity of antioxidant enzymes (superoxide dismutase, peroxidase and catalase) over uninoculated control at 80% FC. 16s rDNA analysis of SIR1 strain revealed its lineage to Bacillus subtilis. Present investigations demonstrated the potential of bacterial partner (B. subtilis) in alleviating drought stress in wheat.
