Complete genome structure of Mesorhizobium loti strain MAFF303099

摘要

Mesorhizobium loti is a member of the rhizobia which performs nitrogen fixation on several Lotus species in determinant-type globular nodules. Nodule formation and nitrogen fixation result from interactions between symbiotic bacteria and host plantsby the sequential expression of a series of genes from both bacteria and hosts. To understand the genetic systems required for the entire process of symbiotic nitrogen fixation, we have initiated the genome sequencing of M. loti strain MAFF303099. Here,we report the complete structure of the M. loti genome, which consists of a single chromosome and two large plasmids, and gene complements of both the chromosome and the plasmids. Characteristic features of the genes and the genome will also be presented
