Summary: | is one of the causal agents of bacterial spot, a disease that seriously affects the production of tomato (
) and pepper (
) worldwide. In Argentina, bacterial spot is found in all tomato producing areas, with
being one of the main species detected in the fields. Previously, we isolated three
strains BNM 208, BNM 214, and BNM 216 from tomato plants with bacterial spot, and found they differed in their ability to form biofilm and in their degree of aggressiveness. Here, the likely causes of those differences were explored through genotypic and phenotypic studies. The genomes of the three strains were sequenced and assembled, and then compared with each other and also with 12 other publicly available
genomes. Phenotypic characteristics (mainly linked to biofilm formation and virulence) were studied
. Our results show that the differences observed earlier between BNM 208, BNM 214, and BNM 216 may be related to the structural characteristics of the xanthan gum produced by each strain, their repertoire of type III effectors (T3Es), the presence of certain genes associated with c-di-GMP metabolism and type IV pili (T4P). These findings on the pathogenicity mechanisms of
could be useful for developing bacterial spot control strategies aimed at interfering with the infection processes. |
