abstract= A novel indole-3-acetic acid-producing bacterium, designated TEGT-2T, was isolated from the roots of Sinopodophyllum hexandrum collected from the Qinling Mountains in shaanxi province, northwestern China, and was subjected to a taxonomic study by using a polyphasic approach. Cells of strain TEGT-2T were Gram-stain-positive, strictly aerobic, endospore-forming rods and motile by means of peritrichous flagella. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain TEGT-2T was a member of the genus Paenibacillus , exhibiting the highest sequence similarity to Paenibacillus pectinilyticus KCTC 13222T (97.9 %), Paenibacillus frigoriresistens CCTCC AB 2011150T (97.3 %), Paenibacillus ferrarius CCTCC AB 2013369T (96.9 %) and Paenibacillus alginolyticus NBRC 15375T (96.5 %). The only menaquinone detected was MK-7, and the major fatty acid was anteiso-C15 : 0. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, two unidentified aminophospholipids, two unidentified phospholipids, an unidentified aminolipid and two unidentified lipids. meso-Diaminopimelic acid was detected in the peptidoglycan. The DNA G+C content was 46.6 mol%. DNA–DNA relatedness values for strain TEGT-2T with respect to its closest phylogenetic relatives Paenibacillus pectinilyticus KCTC 13222T and Paenibacillus . frigoriresistens CCTCC AB 2011150T were lower than 40 %. Based on the phenotypic, phylogenetic and genotypic data, strain TEGT-2T is considered to represent a novel species of the genus Paenibacillus , for which the name Paenibacillus qinlingensis sp. nov. is proposed. The type strain is TEGT-2T (=CCTCC AB 2015258T=KCTC 33806T).,
