The 16S rRNA gene sequence showed they belong to Azospirillum and have less than 96.1 % pairwise similarity with each species in this genus.

New section and species in .

is a monophyletic genus containing seven sections. The number of species in grows rapidly due to reliable and complete sequence data contributed from all over the world. In this study agricultural soil samples from Fujiang, Guangdong, Jiangxi, Shandong, Tibet and Zhejiang provinces of China were collected and analyzed for fungal diversity.

gen. nov. sp. nov., isolated from a crater lake in China.

Two bacterial strains, designated B2N2-7 and B2N2-12, were isolated from Buteha crater lake in the Greater Khingan Mountain of China. The two strains were Gram-stain-negative, non-spore-forming, motile with a single polar flagellum, short rod-shaped bacteria. They were catalase- and oxidase-positive.

sp. nov., sp. nov., and sp. nov. isolated from glaciers.

Three strains, designated as LB1R34, LB3P52 and ZT4R6, were isolated from glaciers located on the Tibetan Plateau, PR China. The strains were Gram-stain-negative, aerobic, rod-shaped, non-motile and yellow. Phylogenetic analysis based on the 16S rRNA gene and genomic sequences indicated that they were related to the members of the genus .

sp. nov., a novel basidiomycetous yeast species isolated from flowers of .

Two yeast strains representing a novel species in the basidiomycetous yeast genus were isolated from flowers of collected in Beijing Olympic Forest Park, PR China. Results of multi-gene phylogenetic analysis indicated that the two strains were closely related to the type strains of (CBS 6294) and (CBS 7687). However, the new isolates differed from CBS 6294 by 1.

Phenotypic divergence of thermotolerance: Molecular basis and cold adaptive evolution related to intrinsic DNA flexibility of glacier-inhabiting Cryobacterium strains.

The link between guanine-cytosine (GC) content and thermal adaptation is controversial. Here, we compared maximum growth temperature (T ) and genomics of 78 Cryobacterium strains to avoid unreliable conclusions resulting from distantly phylogenetic groups. Phylogenomic analysis revealed this taxon had much higher diversification than we knew.
