Isolation and Identification of Rhizobium Species from Root Nodules of Arachis hypogaea L. and Vigna mungo (L.) Hepper in Tamil Nadu, India

摘要

Soil bacteria called rhizobia are very important and have been used in agricultural practices for decades. Rhizobium forms a symbiotic relationship with plant legumes to fix atmospheric nitrogen. Due to this symbiosis, root nodules are formed where in rhizobia fixes atmospheric nitrogen to ammonia. This paper reviews the ability for nitrogen fixation in Arachis hypogaea and Vigna mungo and their genetic and edaphic factors were studied. Genetic analysis was studied using Random Amplified Polymorphic DNA (RAPD)-PCR of the isolates. The nodulation ability of rhizobium was studied and the plants were grown at green house temperature.
