Mesorhizobium australicum 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, Mesorhizobium ciceri bv. biserrulae WSM1271. We describe that the genome size of M. australicum 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 Mesorhizobium ciceri bv. biserrulae WSM1271 that has been integrated into a phenylalanine-tRNA gene.
南方中生根瘤菌WSM2073(T)菌株于2000年从生长在澳大利亚的豆科牧草双荚决明的根瘤中分离得到。这种需氧、具运动性、革兰氏阴性、不产芽孢的杆菌在双荚决明上的固氮效率较低，在从该豆科植物的原始接种菌株，即鹰嘴豆生物型双荚决明根瘤菌WSM1271原位横向转移共生岛后，获得了在双荚决明上结瘤的能力。我们描述了南方中生根瘤菌WSM2073(T)菌株的基因组大小为6,200,534 bp，编码6,013个蛋白质编码基因和67个仅编码RNA的基因。该基因组不包含任何质粒，但有一个来自鹰嘴豆生物型双荚决明根瘤菌WSM1271的455.7 kb基因组岛，已整合到一个苯丙氨酸 - tRNA基因中。
