Semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) analysis of various drought responsive genes from the leaves of sorghum (genotype R-16) under ½ MS and ½ MS + 15% PEG 8000 (drought stress) conditions (Lane M: 100 bp marker; Lane 1 Un-inoculated control; Lane 2 inoculated with E. coli DHα; Lane 3 inoculated with Ochrobactrum sp. EB-165; Lane 4 inoculated with Microbacterium sp. EB-65; Lane 5 inoculated with Enterobacter cloacae strain EB-48; Lane 6 inoculated with Enterobacter sp. EB-14). NA not amplified
