Abstract
The genus Xanthomonas comprises Gram-negative bacteria, many of which are phytopathogens. Xanthomonas fuscans subsp. fuscans is one of the most devastating pathogens affecting the bean plant, resulting in the common bacterial blight of bean (CBB). The disease is mainly foliar and affects a wide variety of bean species, thus acting as the yield-limiting factor for the bean crop. Here, we report the whole-genome sequencing of a new strain of X. fuscans subsp. fuscans, named Xff49, isolated from the infected and symptomatic beans from Capão do Leão, Southern Brazil. The genetic analysis demonstrated the presence of single-nucleotide variants (SNVs) in this strain, potentially affecting the mobilome, cell mobility, and inorganic ion metabolism. In addition, the analysis resulted in the identification of a new plasmid similar to the pAX22 derived from Achromobacter denitrificans, which was named plX, along with plA and plC, previously reported in other strains of X. fuscans subsp. fuscans. Xff49 represents the first Brazilian genome of X. fuscans subsp. fuscans and might provide useful information applicable to the studies of phylogenetics, evolution, and pathogenomics, thereby allowing a better understanding of the genomic features present in the Brazilian strains.
