Accurate identification of sparse heterozygous single-nucleotide variants (SNVs) is a critical challenge for identifying the causative mutations in mouse genetic screens, human genetic diseases and cancer. When seeking to identify causal DNA variants that occur at such low rates, they are overwhelmed by false-positive calls that arise from a range of(More)
A novel actinomycete, designated strain NEAU-ycm1T, was isolated from an edible Chinese black ant (Polyrhachis vicina Roger) and characterized with a polyphasic approach. The organism was found to have morphological and chemotaxonomic characteristics typical of streptomycetes. Phylogenetic analysis based on the almost complete 16S rRNA gene sequence show(More)
A novel actinomycete, designated strain NEAU-Spg16T, was isolated from a soil sample from a pine forest in Songpinggou, Maoxian, southwest China. A polyphasic taxonomic study was carried out to establish the status of strain NEAU-Spg16T. The cell wall peptidoglycan was found to contain LL-diaminopimelic acid and glycine. The major menaquinones were(More)
Genome shuffling is an efficient approach for the rapid engineering of microbial strains with desirable industrial phenotypes. In this study, a strategy of incorporating streptomycin resistance screening into genome shuffling (GS-SR) was applied for rapid improvement of doramectin production by Streptomyces avermitilis NEAU1069. The starting mutant(More)
A novel actinomycete, designated strain NEAU-MES19T, was isolated from pine forest soil in Heilongjiang province, China. A polyphasic study was carried out to establish the taxonomic position of this strain. The organism was found to have morphological and chemotaxonomic characteristics typical of the genus Micromonospora. Phylogenetic analysis of the 16S(More)
A novel endophytic actinomycete, designated strain NEAU-TX2-2(T), was isolated from moss and characterized using a polyphasic approach. The isolate was found to have morphological characteristics typical of the genus Microbispora . The isolate formed longitudinally paired spores on the tips of short sporophores that branched from aerial hyphae. Analysis of(More)
A novel actinomycete, designated strain NEAU-GH7T, was isolated from a lake sediment and characterized using a polyphasic approach. Strain NEAU-GH7T was Gram-stain positive, aerobic, non-spore-forming and produced spherical sporangia. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain NEAU-GH7T formed a monophyletic clade with(More)
A novel actinomycete, strain NEAU-st1T, was isolated from a soil sample collected in Shaanxi province, Northwest China and characterized using a polyphasic approach. 16S rRNA gene sequence similarity studies showed that strain NEAU-st1T belongs to the genus Nonomuraea, being most closely related to Nonomuraea rosea GW12687T (98.91 %), Nonomuraea solani(More)
A novel actinomycete, designated strain NEAU-P5T, was isolated from dandelion root (Taraxacum mongolicum Hand.-Mazz.). Strain NEAU-P5T showed closest 16S rRNA gene sequence similarity to Micromonospora chokoriensis 2–19/6T (99.5 %), and phylogenetically clustered with Micromonospora violae NEAU-zh8T (99.3 %), M. saelicesensis Lupac 09T (99.0 %), M. lupini(More)
A novel actinomycete, designated strain NEAU-zh8T, was isolated from a root of Viola philippica Car collected in China and characterized using a polyphasic approach. 16S rRNA gene sequence similarity studies showed that strain NEAU-zh8T belongs to the genus Micromonospora, being most closely related to Micromonospora chokoriensis 2-9(6)T (99.9 %),(More)
