In this study we analysed three bacterial strains coded L10.10, A4R1.5 and A4R1.12, isolated in the course of a study of quorum-quenching bacteria occurring in Antarctic soil. The 16S rRNA gene sequence was identical in the three strains and showed 99.7% pairwise similarity with respect to the closest related species Pseudomonas weihenstephanensis WS4993. Therefore, the three strains were classified within the genus Pseudomonas. Analysis of housekeeping genes (rpoB, rpoD and gyrB) sequences showed similarities of 84-95% with respect to the closest related species of Pseudomonas, confirming its phylogenetic affiliation. The ANI values were less than 86% to the closest related species type strains. The respiratory quinone is Q9. The major fatty acids are C16:0, C16:1 ω7c/ C16:1 ω6c in summed feature 3 and C18:1 ω7c / C18:1 ω6c in summed feature 8. The strains are oxidase- and catalase-positive. Growth occurs at 4-30°C, and at pH 4.0-10. The DNA G+C content is 58.2-58.3mol %. The combined genotypic, phenotypic and chemotaxonomic data support the classification of strains L10.10, A4R1.5 and A4R1.12 into a novel species of Pseudomonas, for which the name P. versuta sp. nov. is proposed. The type strain is L10.10 (LMG 29628, DSM 101070).

Liaoning cashmere goat is an outstanding breed in China primarily for cashmere production, with strict controls against genetic outflow. Melatonin(MT) is a key factor affecting cashmere growth, and preliminary transcriptome sequencing indicated that melatonin upregulates the expression of the PIP5K1A gene in skin fibroblasts. To predict the physicochemical properties of PIP5K1A in Liaoning cashmere goats, ascertain the tissue localization of PIP5K1A in their skin, and explore the role and mechanism of PIP5K1A in the proliferation of skin fibroblasts.

The Hypericaceae family, comprising nine genera and over seven hundred species, includes plants traditionally used for medicinal purposes. In this study, we performed high-throughput sequencing on three species: , , and , and conducted comparative genomic analyses with related species. The chloroplast genome sizes were 152,654 bp, 122,570 bp, and 137,652 bp, respectively, with an average GC content of 37.

Here, we report the complete genome sequence of a new carlavirus causing mosaic on mint plants in Italy, which we have tentatively named "mint virus C" (MVC). Flexuous particles of around 600 nm were observed using transmission electron microscopy, and next-generation sequencing was performed to determine the nucleotide sequence of the MVC genome, which was found to be 8558 nt long, excluding the poly(A) tail, and shows the typical organization of a carlavirus. The putative proteins encoded by MVC are 44-56% identical to the closest matches in the NCBI database, suggesting that MVC should be considered a member of a new species in the genus Carlavirus.
