The current study aims to isolate as well as characterize endophytic bacteria residing in the roots of Capparis decidua plants collected from the Alwar district of Rajasthan. Thereafter, biochemical and morphological characterization of these endophytic bacteria has been performed to assess plant growth-promoting traits of the bacterial isolates. The results revealed that out of the 12 isolated endophytic bacteria, 100% were found to be motile-rods, with 53.3% of them being gram positive. 100% of the isolated bacterial strains showed catalase activity, indole production, gelatinase activity, urease activity, protease activity, siderophore production and nitrate reduction activity. Furthermore, 58.3% of the endophytic bacteria exhibited amylase activity, lipase activity, VP activity, citrate utilization and phosphate solubilization activity. None of the bacteria showed methyl red test and only 41% of the bacteria produced hydrogen sulfide. All these plant growths promoting attributes exhibited by endophytic bacteria aid in nutrient availability, stress tolerance and development of Capparis decidua.
