Sinorhizobium/Ensifer is a genus of nitrogen-fixing bacteria (rhizobia), two of which (Sinorhizobium meliloti and Sinorhizobium medicae) have been sequenced.

Contents

Etymology

Sinorhizobium is a combination of Medieval Latin sino, -a (which means "China"), Greek rhizo, -a (which means "root"), and New Latin bios (which means "life"). Thus the full name means "a bacterium living in a root in China".[11][14]

Ensifer is from the New Latin term ensifer, which means "sword-bearing" or "sword-bearer".[15]

Proper Name

The name Ensifer was published in 1982 and the name Sinorhizobium was published in 1988. By the rules of the Bacteriological Code (1990 Revision) of the International Committee on Systematics of Prokaryotes (ICSP), the older name (Ensifer) has priority.[16] In response to a request that the single extant species of Ensifer (Ensifer adhaerens) be moved to Sinorhizobium, a special ICSP subcommittee was formed to evaluate the request. It was ultimately ruled that Ensifer retained priority and that all Sinorhizobium species be transferred to the genus Ensifer.[17][18] However, both terms continue to be used in published scientific literature, with Sinorhizobium being the more common.

Deprecated Species

Two species have been described which have since been reclassified into existing species: Sinorhizobium morelense (now Ensifer adhaerens)[19][16] and Sinorhizobium xinjiangense (now Sinorhizobium fredii[20][21]—though there is some dissent[22]).
