Plant pathogenic bacteria of the genus Xanthomonas display high levels of genetic diversity and cause remarkable damage to about 400 plant species. In 2001–2008, a new group of strains of Xanthomonas arboricola has been found as pathogens on novel host plants such as wheat, rye, barley, tomato, sunflower, and brassicas in Russia. Physiological tests and multilocus sequence typing (MLST) analysis confirmed their position within the Xanthomonas arboricola species. The obtained draft genome sequence of Xanthomonas arboricola strain 3004 from barley plants, also virulent to sunflower, brassicas, and chestnut, has demonstrated an evidence for the lateral gene transfer (LGT) of the virulence genes. It can be suggested that the virE and other genes of T4SS, obtained due to LGT, may contribute to the host range extension. Thus, T4SS genes can be used as the target for group-specific PCR analysis of this emerging pathogen of cereals and oilseeds. We propose to use virB3, virB4, and virB9 genes to design a detection system.
