Drought stress mitigation in Vigna radiata by the application of root-nodulating bacteria

Plant growth promoting rhizobacteria (PGPR) facilitates plant growth and are of potential use as bio-fertilizer. Pulses are an important protein source in the vegetarian diet and being legumes harbour members of the Rhizobiaceae that form symbiotic relationships and nodules involved in nitrogen fixation. Vigna radiata is one such pulse crop popular in India. Nodulating bacteria were also found to mitigate biotic and abiotc stress and may be used as an alternative to chemical fertilizer for a sustainable agriculture. Here, we review rhizobial species isolated from V. radiata that have offered an efficient drought stress tolerance.
