Endophytic nonrhizobial bacteria, Chryseobacterium indologenes, Endophytic non rhizobial bacterial stain AM2 was isolated from root nodules of Vigna radiate. The bacterium was Gram-negative, yellow pigmented, nonspore forming, motile and oxidase positive. Phylogeny of 16S rRNA gene sequences revealed that the strain belonged to the genus Chryseobacterium, a member of family Flavobacteriaceae. Closest phylogenetic relatives to it were Chryseobacterium indologenes strain LMG8337 and Chryseobacterium indologenes strain NBRC 14944, respectively was showing 97% and 95% 16S rRNA gene sequence similarity. Strain showed presence of nifH gene of ~380 bp. It also exhibit nitrogen fixation ability around N g-1 of glucose consumed with indole acetic acid producing capability of µg ml-1 ., nifH gene, | Chryseobacterium indologenes a novel root nodule endophyte in Vigna radiata
