Complete genome sequence of Mesorhizobium opportunistum type strain WSM2075T

摘要

strain WSM2075^T was isolated in Western Australia in 2000 from root nodules of the pasture legume Biserrula pelecinus that had been inoculated with bv. biserrulae WSM1271. WSM2075^T is an aerobic, motile, Gram negative, non-spore-forming rod that has gained the ability to nodulate B. pelecinus but is completely ineffective in N2 fixation with this host. This report reveals that the genome of strain WSM2075^T contains a chromosome of size 6,884,444 bp, encoding 6,685 protein-coding genes and 62 RNA-only encoding genes. The genome contains no plasmids, but does harbor a 455.7 kb genomic island from bv. biserrulae WSM1271 that has been integrated into a phenylalanine-tRNA gene.
