<i>Knoellia altitudinis</i> sp. nov., <i>Knoellia pratensis</i> sp. nov., <i>Knoellia terrae</i> sp. nov. and <i>Knoellia tibetensis</i> sp. nov., four novel UV radiation-resistant actinobacteria isolated from Tibet Autonomous Region, China.

ABSTRACT: Four Gram-stain-positive, aerobic, non-motile and non-spore-forming actinobacterial strains (CPCC 206391^T, CPCC 206453^T, CPCC 206435^T and CPCC 206450^T) were isolated from soil samples collected from Tibet Autonomous Region, China. The 16S rRNA gene sequences of these four strains showed close relations to members of the genus Knoellia of the family Intrasporangiaceae, with similarities of 96.1-99.4% to the validly named species of Knoellia. In the phylogenetic trees based on 16S rRNA gene sequences and the core genome, these isolates clustered into the genus Knoellia clade within the lineage of the family Intrasporangiaceae. Genome relatedness index values between these strains and their phylogenetic neighbours,
