对燕麦叶枯病和玉米叶枯病的病原菌--麦草假单胞菌1909和白色沉淀假单胞菌Rosen 1922的生理生物学特性进行了比较。除少数次要的生理特性外，大多数特性与本文测定的在佐治亚州和佛罗里达州获得的白色沉淀性假单胞菌分离株和“lecto”型菌株(Atcc 19860)的特性相同。从脱氧核糖核酸(DNA)-DNA再结合实验判断，所有的白色沉淀菌在基因上都有密切的亲缘关系。而从高粱中分离的荧光假单胞菌5D417和从小麦中分离的非荧光萎缩假单胞菌PA13的DNA与白色沉淀假单胞菌的DNA不能结合。白色沉淀菌也具有相对较高的鸟嘌呤+胞嘧啶(G+C)含量(72.2moL%)，而萎缩巴氏原虫和雄黄地平革兰氏菌的G+C含量为57.8mol%。
The nomenspecies Pseudomonas avenae Manns 1909 and Pseudomonas alboprecipitans Rosen 1922, causal agents of leaf blight of oats and leaf blight of corn, have been compared with respect to their physiological and biological properties as described in the early literature. Except for a few minor physiological characters, most of the properties were identical to those determined herein with P. alboprecipitans isolates obtained in Georgia and Florida and with the “lecto” type strain (ATCC 19860). All isolates of P. alboprecipitans were closely related genetically as judged from deoxyribonucleic acid (DNA)-DNA reassociation experiments. On the other hand, DNA of P. alboprecipitans failed to reassociate with DNA of fluorescent Pseudomonas syringae 5D417 and Pseudomonas andropogonis PA146 isolated from sorghum or the nonfluorescent Pseudomonas atrofaciens PA13 isolated from wheat. P. alboprecipitans isolates also possessed DNA of relatively high guanine plus cytosine (G+C) content (72.2 mol%) as compared to the 57.8 mol% G+C of P. atrofaciens and P. andropogonis.
