Chair's comments: the whole chromosome sequence of Sinorhizobium meliloti strain 1021

摘要

Sinorhizobium meliloti strain 1021 is a free-living, gram-negative soil bacterium, and symbiont of alfalfa (Medicago saliva). Its genome consists of three large replicons - a chromosome and two megaplasmids - that have been entirely sequenced by an international consortium (Galibert 2001). The pair M. truncatula and S. meliloti has been chosen by many international groups and emerges as the model for symbiosis and nitrogen fixation studies worldwide (along with Lotus japonicus and Mesorhizobium loti
