Plants respond to abiotic stresses through a series of molecular, cellular and physiological changes. These responses are further
influenced by the interactions between host plant and the associated rhizospheric and endophytic microorganisms. The endophytic
microorganisms, due to their intimate proximity with the host plant, are considered to have major influence on plant’s physiological
responses. In the present study, three drought tolerant and plant growth promoting maize seed endophytic bacteria, Bacillus sp. MSEB
17, Bacillus sp. MSEB 72 and Bacillus sp. MSEB 78 were used as seed inoculants in maize (var Bioseed 9681) under drought stress
conditions in a growth chamber pot study and their influence on four drought responsive genes (Zmdhn1, GRMZM2G055844,
GRMZM2G467339 and GRMZM2G109448) in maize leaves was studied by real time PCR using specific primers. The influence of
inoculation on host plant’s response to drought was evident from altered expression of target genes when compared with uninoculated
plants. Notably, inoculation with MSEB 17 increased the expression of three target genes, Zmdhn1 (dehydrin) gene, GRMZM2G467339
gene and GRMZM2G109448 gene by several folds. This study revealed the role of endophytic in alleviating the effect of drought stress
in maize plants through regulating plant growth and physiological response
