The generic epithet Ensifer derives from the
Latin noun ensifer, "sword-bearer".[3] The synonym Sinorhizobium is a combination of
Medieval Latin noun sino ("China"), the
Classical Greek noun rhiza ("root"), and the
Classical Greek noun bium ("life"). Thus, the Neo-Latin generic epithet of the synonym Sinorhizobium means "a Rhizobium isolated from China", in turn referring to the related genus Rhizobium ("root-associated life form").[18][9]
Proper name
The name Ensifer was published in 1982 and the name Sinorhizobium was published in 1988 thus the latter is regarded as a later synonym and by the rules of the Bacteriological Code (1990 Revision) of the International Committee on Systematics of Prokaryotes (ICSP), the older name (Ensifer) takes priority.[27] 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.[28][29] However, both terms continue to be used in published scientific literature, with Sinorhizobium being the more common.[30]
Deprecated species
Two species have been described which have since been reclassified into existing species: Sinorhizobium morelense (now Ensifer adhaerens)[27][31] and Sinorhizobium xinjiangense (now Ensifer fredii[32][33]—though some dissent exists[16][34]).
