Complete genome sequence of Mesorhizobium australicum type strain (WSM2073T)

摘要

strain WSM2073^T was isolated from root nodules on the pasture legume Biserrula pelecinus growing in Australia in 2000. This aerobic, motile, gram negative, non-spore-forming rod is poorly effective in N2 fixation on B. pelecinus and has gained the ability to nodulate B. pelecinus following in situ lateral transfer of a symbiosis island from the original inoculant strain for this legume, bv. biserrulae WSM1271. We describe that the genome size of strain WSM2073^T is 6,200,534 bp encoding 6,013 protein-coding genes and 67 RNA-only encoding genes. This genome does not contain any plasmids but has a 455.7 kb genomic island from bv. biserrulae WSM1271 that has been integrated into a phenylalanine-tRNA gene.
