“…There are a few symbiovar names that, if they had been proposed as species epithets, would have been corrected by the nomenclature editors because they are not well formed according to the rules for Latin names. Thus, lysilomaefficiens [ 25 ] would be better as lysilomefficiens (based on the stem Lysilom- of the host plant name), phaseolarum [ 40 ] would be phaseolearum (of the tribe Phaseoleae), oxytropis [ 41 ] would be oxytropidis (of Oxytropis ), maamori [ 42 ] would be maamorensis (from the place Maamora). While authors may, in future, prefer to use the corrected form, we consider either version to be acceptable.…”

“…astragalus/caraganae have been used to label clades in a nodC phylogeny [ 55 ], but the authors did not describe them in the text, so we consider that they did not define these potential symbiovars and we have not included the names in Table 1 . Several later publications have repeated the names [ 41 42 56 ], but still with no formal definition.…”

Rhizobia are bacteria that form nitrogen-fixing nodules in legume plants. The sets of genes responsible for both nodulation and nitrogen fixation are carried in plasmids or genomic islands that are often mobile. Different strains within a species sometimes have different host specificities, while very similar symbiosis genes may be found in strains of different species. These specificity variants are known as symbiovars, and many of them have been given names, but there are no established guidelines for defining or naming them. Here, we discuss the requirements for guidelines to describe symbiovars, propose a set of guidelines, provide a list of all symbiovars for which descriptions have been published so far, and offer a mechanism to maintain a list in the future.
