These results indicate that the relationship between the pathogenicity of the causal bacterium and the resistance of host plants is very complex, and suggest that pathogenic diversity of X. The Asian isolates exhibited a wide host range against the international differential rice cultivars, but almost all of them were avirulent to Leersia plants. japonica found to be resistant to all test isolates collected from Japan. japonica plants gave reactions different those of L. oryzoides plant collected from Niigata Prefecture showed a susceptible reaction to some Race III isolates. oryzoides plants to Race I and II isolates were similar to that of L. Race III is known to have a wider range pathogenicity to rice cultivar groups compared with Race I and II. sayanuka plants were found susceptible to all Race II isolates and some Race I isolates, but were resistant to all Race III isolates. oryzae isolates obtained from various locations in Japan and from 11 Asian countries. japonica, were collected from various parts of Japan and were inoculated with the X. Plants of three species of Leersia, namely, L. oryzae, the causal bacterium for rice blight and Leersia grasses, the alternative weed hosts of the disease. The present study was conducted to determine if there is specificity in the host-pathogen relationship between the isolates of Xanthomonas oryzae pv.
