Isolation and characterization of Rhizobium sp. from a collar rot tolerant groundnut (Arachis hypogaea L.) variety

Abstract

Groundnut, a major pulse crop, is prone to fungal diseases especially collar rot at seed germination and early seedling stage. In the present study, symbiotic bacteria was isolated and characterised from a collar rot resistant groundnut variety, Mallika and identified as Rhizobium pongamiae following biochemical and molecular characterization (NCBI Acc. No. MK770416). The bacterial isolate on cross inoculation, may be useful in improving crop productivity and enhancing collar rot disease tolerance in susceptible crops.

Isolation and Characterization of Plant Growth Promoting Bacteria from Root Nodules of Cicer arientinum L.

“…Isolation of bacterial strains, especially, root nodulating bacteria in legumes with plant growth promoting activities assumes significance as it is reported to provide protection to biotic [22] and abiotic stress [23][24][25].…”
