Abstract:
:The infectivity of Agrobacterium tumefaciens strain B6 was inhibited about 50% when these bacteria were inoculated on potato discs with equal viable cell counts of a weakly virulent strain of A. tumefaciens (B-48) or autoclaved strains of B6 or B-48. Inhibition by B-48 or autoclaved B6 could still be obtained when these cells were added up to a maximum of 10 minutes after the addition of viable B6. Maximum inhibition occurred when these cells were added 10 minutes prior to the addition of B6. There was no inhibition observed when equal cell counts of B6 were added along with a Gram-positive bacterium or yeast cell, while inhibition was observed when these B6 cells were added simultaneously with other Gram-negative cells. These results suggest that a physical, specific bacterial attachment that occurs within 10 minutes is necessary for tumor formation on potato discs.
