A Gram-negative, aerobic and non-motile rod, designated Y4(T), was isolated from a cucumber leaf from Pinggu District, east Beijing, PR China. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain Y4(T) was most closely related to Luteimonas aquatica RIB1-20(T) (96.7% 16S rRNA gene sequence similarity). DNA-DNA relatedness between strain Y4(T) and L. aquatica RIB1-20(T) was 42.5 ± 3.9%. The predominant fatty acids were iso-C(15:0), iso-C(17:1)ω9c, iso-C(16:0) and iso-C(17:0). The major ubiquinone was Q-8. The DNA G+C content of the type strain was 69.9 mol%. Based on the evidence above, strain Y4(T) represents a novel species of the genus Luteimonas, for which the name Luteimonas cucumeris sp. nov. is proposed. The type strain is Y4(T) ( = CGMCC 1.10821(T) = KCTC 23627(T)).
一株革兰氏阴性、需氧、不运动的杆菌，被命名为 Y4(T)，从中国北京平谷区的黄瓜叶中分离得到。基于 16S rRNA 基因序列的系统发育分析表明，菌株 Y4(T)与水生黄单胞菌 RIB1-20(T)（相似度为 96.7%）最为密切相关。菌株 Y4(T)与水生黄单胞菌 RIB1-20(T)之间的 DNA-DNA 同源性为 42.5±3.9%。主要脂肪酸为 iso-C(15:0)、iso-C(17:1)ω9c、iso-C(16:0)和 iso-C(17:0)。主要的醌类为 Q-8。模式株的 DNA G+C 含量为 69.9 mol%。基于上述证据，菌株 Y4(T)代表了黄单胞菌属的一个新种，命名为黄瓜黄单胞菌（Luteimonas cucumeris）。模式株为 Y4(T)（=CGMCC 1.10821(T)=KCTC 23627(T)）。
