   ABSTRACT We report the draft genome of the gram-positive bacteriumPaenibacillus turicensisDSM 14349^T,isolated from the cerebrospinal fluid of a male patient. The 4.8 Mbp genome encodes 4,551 genes, including 4,423 protein-coding sequences, some of which may contribute to its ability to survive in a nutrient-poor environment.

   ABSTRACT A novelSaccharomycotinayeast strain, yHQL494, was isolated from the rose hip of the wild roseRosa californicafrom Castle Crags State Park, California, USA. Phylogenetic analyses of both whole genome data and the sequences from the D1/D2 region of the large ribosomal subunit (LSU) rRNA gene placed strain yHQL494 within the genusLachanceaand grouped it into a clade withLachancea lanzarotensisandLachancea meyersii. Taxogenomic analyses were conducted on publicly available genome sequences to gain a deeper insight into the carbon and nitrogen gene‐trait associations across theLachanceaclade. The results of these analyses were found to be consistent acrossLachanceaspecies. Growth assays and microscopic analyses were conducted to determine the physiological characteristics of strain yHQL494, including the presence of hyphae or pseudohyphae, ascospore formation, fermentation abilities, and assimilation of carbon and nitrogen compounds. Based on the phenotypic and genomic characteristics of the strain yHQL494^T(=NRRL Y‐64858^T, =CBS 18,574^T), we propose a new species,Lachancea rosaesp. nov. f.a.
