Project description:Comparative genomic hybridizations obtained with an original Agrobacterium tumefaciens strain C58 genome-based micro-array were used to detect the presence or absence of genes homologous to those of strain C58 in 25 agrobacterial strains. These strains included six other members of genomovar G8, one to three strains for each of the nine other A. tumefaciens genomovars and one for A. larrymoorei, a sister species of the A. tumefaciens complex. An original probabilistic method was used to segment C58 replicon sequences into regions, that are absent or present in tested strains, allowing us to detect the presence of homologues of C58 coding sequences (CDSs) in tested strains.
