abstract= A Gram-stain-negative, rod-shaped, phototrophic bacterium, strain JA793T, was isolated from rhizosphere soil of paddy. The strain was capable of growing phototrophically and chemotrophically. Bacteriochlorophyll-a and carotenoids of the spirilloxanthin series were present as photosynthetic pigments. The major fatty acid of strain JA793T was C18 : 1ω7c/C18 : 1ω6c (>65.7 %), with minor amounts of C16 : 0, C16 : 1ω7c/C16 : 1ω6c, C20 : 2ω6,9c, C16 : 0 3-OH, C14 : 0 and C18 : 0 also present. Ubiquinone-10 and rhodoquinone-10 were present as primary quinones. Phosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine were the major polar lipids, while minor amounts of amino lipids and unidentified lipids were also present. The G+C content of genomic DNA of strain JA793T was 68.7 mol%. 16S rRNA gene-based EzTaxon-e blast search analysis of strain JA793T indicated highest sequence similarity with members of the genus Rhodoplanes in the family Hyphomicrobiaceae of the class Alphaproteobacteria . Strain JA793T had high sequence similarity with Rhodoplanes elegans AS130T (98.6 %), Rhodoplanes roseus 941T (98 %), Rhodoplanes pokkaliisoli JA415T (97.5 %) and Rhodoplanes piscinae JA266T (97.3 %) and other members of the genus Rhodoplanes (<97 %). However, strain JA266T was related by <59 % (based on DNA–DNA hybridization) to Rhodoplanes elegans DSM 11907T ( = AS130T), Rhodoplanes roseus DSM 5909T ( = 941T), Rhodoplanes pokkaliisoli JA415T and Rhodoplanes piscinae JA266T. The genomic information was well supported by phenotypic and chemotaxonomic data to classify strain JA793T as a representative of a novel species in the genus Rhodoplanes , for which the name Rhodoplanes oryzae sp. nov. is proposed. The type strain is JA793T ( = NBRC 109406T = KCTC 15260T).,
