Subjective Synonym

It is proposed that Agrobacterium radiobacter has priority as the earlier heterotypic (subjective) synonym when it is united with Agrobacterium tumefaciens. The nomenclatural status of A. tumefaciens as a later heterotypic synonym of the united species is not lost and it remains the type species of the genus. Request for an Opinion.

Phage Population

Neutralization tests using antisera for 4 of 16 Agrobacterium radiobacter phages indicated that all 16 phages belonged to one serological group. Within the group the phages were differentiated by the neutralization velocity constants, the K-values. Occasionally the antisera inactivated heterologous phages more rapidly than the homologous phages. With some systems the reactions were not of the first order throughout the course of neutralization. This anomaly in the kinetics was not due to hereditary antigenic inhomogeneity in the phage population, as indicated by curves obtained with the parent phage and with isolates which resisted neutralization. Adaptation of the phages to a heterologous host lowered the original K-values with homologous antisera without a change in the host range. None of the four antisera neutralized any of five phages of Agrobacterium tumefaciens, collectively lysing 16 strains of A. radiobacter, including homologous hosts of the phages used in the immunizations.

Crown gall was found mostly on vinifera grape (Vitis vinifera L.) cultivars in Ontario vineyards. The galls were usually small and aggregated along the trunk and cane; large woody galls were less common. Vines affected by crown gall died back in 3–4 years after planting. All the nine strains of Agrobacterium tumefaciens (Smith and Townsend) Conn isolated from galls corresponded to biotype 3 in determinative tests and were pathogenic on Datura, tobacco, tomato, and sunflower plants. Eight strains were sensitive to agrocin 84 on amended Stonier's medium. They were suppressed if inoculation was preceded 6 h earlier by Agrobacterium radiobacter strain K84 at wound sites on Datura and tomato plants.
