title: Agrobacterium radiobacter (Beijerinck and van Delden 1902) Conn 1942 has priority over Agrobacterium tumefaciens (Smith and Townsend 1907) Conn 1942 when the two are treated as members of the same species based on the principle of priority and Rule 23a, Note 1 as applied to the corresponding specific epithets. Opinion 94. Judicial Commission of the International Committee on Systematics of Prokaryotes.
abstract: The Judicial Commission affirms that, according to the Rules of the International Code of Nomenclature of Bacteria (including changes made to the wording), the combination Agrobacterium radiobacter (Beijerinck and van Delden 1902) Conn 1942 has priority over the combination Agrobacterium tumefaciens (Smith and Townsend 1907) Conn 1942 when the two are treated as members of the same species based on the principle of priority as applied to the corresponding specific epithets. The type species of the genus is Agrobacterium tumefaciens (Smith and Townsend 1907) Conn 1942, even if treated as a later heterotypic synonym of Agrobacterium radiobacter (Beijerinck and van Delden 1902) Conn 1942.
