SEROLOGICAL COMPARISONS BETWEEN STRAINS OF AGROBACTERIUM TUMEFACIENS

Abstract
Agrobacterium tumefaciens B6and Agrobacterium tumefaciens B6TP were compared serologically. Antigen–antibody precipitations produced by the use of the agar double-diffusion technique show cross reactions indicating similarity in addition to a line of precipitation specific for the virulent strain, Agrobacterium tumefaciens B6.
