Rhizobium sp. strain IRBG74 is the first known nitrogen-fixing symbiont in the Agrobacterium/Rhizobium clade that nodulates the aquatic legume Sesbania sp. and is also a growth-promoting endophyte of wetland rice. Here, we present the sequence of the IRBG74 genome, which is composed of a circular chromosome, a linear chromosome, and a symbiotic plasmid, pIRBG74a.
根瘤菌属菌株IRBG74是农杆菌/根瘤菌分支中首个已知的固氮共生体,它能使水生豆科植物田菁结瘤,也是湿地水稻的促生长内生菌。在此,我们展示了IRBG74基因组序列,其由一条环状染色体、一条线性染色体和一个共生质粒pIRBG74a组成。
