摘要： A novel endophytic bacterium, strain 1DrF-4(T), isolated from rice roots, was characterized on the basis of its phenotypic characteristics and genotypic information. The novel strain was Gram-positive -staining, endospore-forming, facultatively anaerobic, motile and rod-shaped. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain 1DrF-4(T) formed a monophyletic clade within the genus Paenibacillus. The most phylogenetically related species was Paenibacillus pinesoli KACC 17472(T), with which strain 1DrF-4(T) showed 16S rRNA gene sequence similarity of 95.2%. 168 rRNA gene sequence similarities with type strains of other species of the genus Paenibacillus were less than 95%. The predominant cellular fatty acids were anteiso-C-15:0 (61.1%) and C-16:0 (11.1%), which is one of the characteristic traits of the genus Paenibacillus. The quinone system contained exclusively menaquinone MK-7. The polar lipid profile contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, glycolipid and an unknown phospholipid. The DNA G+C content was 50.16 mol%, which was within the range reported for species of the genus Paenibacillus. Characterization by genotypic, chemotaxonomic and phenotypic analysis indicated that strain 1DrF-4(T). (=ACCC 19927(T)=JCM 30486(T)) represents a novel species of the genus Paenibacillus, for which the name Paenibacillus oryzae sp. nov. is proposed.
