水稻白叶枯病是由稻黄单胞菌水稻致病变种Xanthomonas oryzae pv.oryzae引起的细菌性病害[1-2],该病菌具有明显的致病力差异,有关其致病力分化研究一直备受关注[2-3]。水稻白叶枯病是安徽省水稻上的重要病害,自20世纪90年代承河元等[4]确定安徽省水稻白叶枯病菌中存在0、Ⅰ、?
Bacterial blight is a bacterial disease caused by Xanthomonas oryzae pv. Oryzae, a disease caused by the rice pathogenicity of Y. difficile [1-2]. This pathogen has obvious pathogenicity difference, and its pathogenic differentiation has been studied Much attention [2-3]. Rice bacterial leaf blight is an important disease on rice in Anhui Province. Since the 1990s, Cheng et al. [4] identified the presence of 0, Ⅰ,
