Six psychrotolerant, Gram-stain-negative, aerobic bacterial strains, designated as LB1P51, LB2P87, LB2P84, LB3P48, LB3R18 and XS2P67, were isolated from glaciers on the Tibetan Plateau, PR China. The results of 16S rRNA gene analysis confirmed their classification within the genus . Strain LB2P87 displayed the highest sequence similarity to 0533 (98.18 %), while strain LB1P51 exhibited the highest sequence similarity to CGMCC 1.5380 (98.15 %). Strains LB2P87 and LB1P51 had genome sizes of 3.8 and 3.9 Mb, respectively, with DNA G+C contents of 34.2 and 34.1 %, respectively. Pairwise average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) calculations revealed that these strains represented two distinct species within the genus . The results of phylogenomic analysis using 606 core genes indicated that the six strains formed a distinct clade and were most closely related to CGMCC 1.5380. The ANI and dDDH values between the two species and other members of the genus were below 90.3 and 40.1 %, respectively. Genome relatedness, the results of phylogenomic analysis and phenotypic characteristics collectively support the proposal of two novel species of the genus : sp. nov. (LB1P51 = CGMCC 1.11237 = NBRC 114813) and sp. nov. (LB2P87 = CGMCC 1.11249 = NBRC 114814).

Introduction: Nipah virus (NiV) is one of a group of highly pathogenic viruses classified within the Henipavirus genus. Since 2012 at least 11 new henipa-like viruses have been identified, including from new locations and reservoir hosts; the pathogenicity of these new viruses has yet to be determined, but two of them have been associated with morbidity, including fatalities.
Methods: The efficacy and cross-reactivity of two vaccine candidates derived from the soluble glycoproteins of both NiV and Hendra virus (HeV) was evaluated in our recently established hamster model.

Introduction: Plant respiratory burst oxidase homologs (Rbohs) are essential in the generation of reactive oxygen species (ROS) and play critical roles in plant stress responses. Despite their importance, Rbohs in poplar species remain under-explored, especially in terms of their characteristics and functional diversity across different species within the same genus.
Methods: In this study, we employed bioinformatics methods to identify 62 Rboh genes across five poplar species.

Background: The genus Solanum is a diverse group of flowering plants with significant economic importance. Within this genus, the subgenus Leptostemonum, comprising spiny solanums, is particularly noteworthy due to its high species diversity and endemism. Solanum ensifolium, a member of this subgenus, is a critically endangered species endemic to Puerto Rico and known locally as erubia.

The complete genome sequence of fig leaf mottle-associated virus 2 (FLMaV2), a positive-sense single-stranded RNA virus with a genome length of 16,925 nucleotides, was determined via RT-PCR and rapid amplification of cDNA ends (RACE). Its genome organization resembles those of little cherry virus 2 (LChV2) and yam asymptomatic virus 1 (YaV1), both of which are currently classified as members of the genus Ampelovirus but differ from typical ampeloviruses. Phylogenetic analysis based on amino acid sequences of the RNA-dependent RNA polymerase and coat protein of members of the family Closteroviridae showed that FLMaV2 clustered with LChV2 and YaV1.
