Nomenclatural History
The species Agrobacterium tumefaciens was originally described by Conn 1942. This name appeared on the Approved Lists of Bacterial Names 1980. This name was placed onto the nomina taxorum conservanda by Judicial Opinion 33 in 1970. This name was affected by Judicial Opinion 94 in 2014. Hördt et al. published an emended description of this species in 2020. Young et al. established this name as an earlier heterotypic synonym of (Beijerinck and van Delden 1902) Young et al. 2001 in 2001.

The specific epithet 'tumefaciens' is conserved against the epithet 'radiobacter' in the context of Agrobacterium, but not in the context of other genera. Judicial Opinion 94 conflicts with Judicial Opinion 33 on the priority of these two names. A new request by Velázquez et al. 2020 asserts that ATCC 4720 (16S:MT534522, WGS:JAAQPP000000000) is the authentic type strain and requests that the synonymy with A. radiobacter be retracted.
