The genus Xanthomonas has been subject of numerous taxonomic and phylogenetic studies and was first described as Bacterium vesicatorium as a pathogen of pepper and tomato in 1921. Dowson later reclassified the bacterium as Xanthomonas campestris and proposed the genus Xanthomonas.
Parent taxon: Xanthomonas Dowson 1939 (Approved Lists 1980) Assigned by: Swings J, Van Den Mooter M, Vauterin L, Hoste B, Gillis M, Mew TW, Kersters K. Reclassification of the causal agents of bacterial blight (Xanthomonas campestris pv. oryzae) and bacterial leaf streak (Xanthomonas campestris pv. oryzicola) of rice as pathovars of Xanthomonas oryzae (ex Ishiyama 1922) sp. nov., nom. rev. Int.
The two pathovars pv. oryzae and pv. oryzicola are now classified in the species Xanthomonas oryzae (Swings et al., 1990). Vauterin et al. (1995) confirmed the present taxonomic position of this and other species of Xanthomonas by molecular and biochemical methods.
The genus Xanthomonas comprises an important group of Gram-negative plant pathogenic bacteria, which infect approximately 350 different plants, and cause great economic losses worldwide (1, 2). One member of this genus, Xanthomonas oryzae pv. Oryzae (Xoo) is an important rice pathogen.
A few informations on the role of hormones in the response of rice plant to the infection of fungal pathogen, such as, Magnaportha oryzae and bacterial pathogen, such as, Xanthomonas oryzae pv. oryzae are available. In order to facilitate the infection in root, how the nematodes interact with the rice hormonal pathway is not well known.
The study of Xanthomonas oryzae pv. oryzae (Xoo) populations in the Philippine archipelago is particularly relevant because they have been derived from the ancestral population in Asia and represent one of the best characterized Xoo collections across the region. While the country is a natural laboratory for the deployment of improved varieties carrying large-effect genes, some of these.
