New serogroups of Xanthomonas oryzae pv. oryzae
Studies were carried out in Hawaii, US, to detect and differentiate the serological diversity of Xanthomonas oryzae pv. oryzae (EPPO A1 pest) by the use of monoclonal antibodies. A total of 259 X.o. pv. oryzae strains representing various rice-growing regions of the world were investigated with several monoclonal antibodies. Two new serogroups of the pathogen from Nepal and India were distinguished by the monoclonal antibodies.
