A Gram-negative, aerobic bacterium, designated strain FR1439T, was isolated from the soil of Dokdo in the Republic of Korea. The cells of strain FR1439T were catalase- and oxidase-positive, motile and rod-shaped. Phylogenetic analysis of the 16S rRNA gene sequence revealed that it represents a distinct line of descent within the genus Pseudomonas. The levels of DNA-DNA relatedness between strain FR1439T and type strains of phylogenetically related species, namely Pseudomonas flavescens, Pseudomonas mendocina, Pseudomonas pseudoalcaligenes and Pseudomonas straminea, ranged from 28 to 37%. Several phenotypic characteristics, together with the cellular fatty acid composition, can be used to differentiate strain FR1439T from related pseudomonads. On the basis of the polyphasic taxonomic evidence presented in this study, strain FR1439T represents a novel species, for which the name Pseudomonas segetis sp. nov. is proposed. The type strain is FR1439T (=IMSNU 14101T=CIP 108523T=KCTC 12331T).
从大韩民国独岛的土壤中分离出一株革兰氏阴性需氧细菌，命名为FR1439T菌株。FR1439T菌株的细胞过氧化氢酶和氧化酶呈阳性，具运动性，呈杆状。对16S rRNA基因序列的系统发育分析表明，它代表假单胞菌属内一个独特的谱系。FR1439T菌株与系统发育相关物种（即荧光假单胞菌、门多西假单胞菌、类产碱假单胞菌和稻草假单胞菌）的模式菌株之间的DNA-DNA相关性水平在28%至37%之间。一些表型特征以及细胞脂肪酸组成可用于区分FR1439T菌株与相关假单胞菌。基于本研究提供的多相分类学证据，FR1439T菌株代表一个新物种，为此提议将其命名为Pseudomonas segetis sp. nov.。模式菌株为FR1439T（=IMSNU 14101T=CIP 108523T=KCTC 12331T）。
