野油菜黄单胞菌致病变种野生型和诱变株的细菌学和病理学特性之间的关系。他研究了。在菲律宾发现的三个致病群的大多数菌株在生化和生理特性上是同质的。用N-甲基-N-硝基-N-亚硝基胍（NTG）处理两个不同致病群的亲本菌株PXO 61 PT和PXO 63 -6PT，得到14个诱变突变体，根据对水稻的致病力和在蛋白胨-蔗糖琼脂培养基上的菌落颜色，将其分为3种类型。弱毒性突变体比亲本菌株在所有水稻品种上的病变都要短。
The relationship between bacteriologicaland pathological characteristics of wild types and induced mutants of Xanthomonas campestris pv. oryzae was studied. Most strains of the three pathogenic groups found in the Philippines were homogeneous in biochemical and physiological characteristics. Two parent strains, PXO61PT and PXO63-6PT, of different pathogenic groups were treated with N-methyl-N-nitro-N-nitrosoguanidine (NTG) and 14 induced mutants were obtained, which were classified into three types on the basis of virulence to rice and colony color on peptone-sucrose agar medium. Weakly virulent mutants developed shorter lesions than the parent strains on all rice cultivars that were tested.
