Horizontal gene transfer plays a major role in the pathological convergence of Xanthomonas lineages on common bean.

ABSTRACT:

Background

Host specialization is a hallmark of numerous plant pathogens including bacteria, fungi, oomycetes and viruses. Yet, the molecular and evolutionary bases of host specificity are poorly understood. In some cases, pathological convergence is observed for individuals belonging to distant phylogenetic clades. This is the case for Xanthomonas strains responsible for common bacterial blight of bean, spread across four genetic lineages. All the strains from these four lineages converged for pathogenicity on common bean, implying possible gene convergences and/or sharing of a common arsenal of genes conferring the ability to infect common bean.

Results

To search for genes involved in common bean specificity, we used a combination of whole-genome analyses without a priori,
