title: Repeat domain diversity of avrBs3-like genes in Ralstonia solanacearum strains and association with host preferences in the field.
abstract: Genes homologous to avrBs3 of Xanthomonas were detected in 309 strains of Ralstonia solanacearum biovars 3, 4, and 5 but not biovar 1 or 2. A statistically significant association between the originating plant species and internal repeats of the gene was found. Sequences of repeats and variation between nearly clonal strains revealed evidence of frequent recombination.
