During a Gryllidae survey in the Southern Cameroonian Plateau, one new species of the genus Gymnogryllus (Orthoptera, Gryllidae, Gryllinae) was discovered and described, namely Gymnogryllus bilongi Um Nyobe & Kekeunou sp. nov. This finding extends the number of species known of this genus in Cameroon at two and proposes a key for African species.

Characterization of mint virus C, a new member of the genus Carlavirus.

Institute for Sustainable Plant Protection, CNR, Strada delle Cacce 73, 10135, Torino, Italy.
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.

Background matching and disruptive coloration are defense mechanisms of animals against visual predators. Disruptive coloration tends to evolve in microhabitats that are visually heterogeneous, while background matching is favored in microhabitats that are chromatically homogeneous. Controlling for the phylogeny, we explored the evolution of the coloration and the marking patterns in the sexual dichromatic and widely distributed neotropical grasshoppers of the genus Sphenarium.

is a species from the genus (Meliaceae) and the chemical constituent has not been widely explored. A new cycloartane-type triterpenoid, pachyphyllanone (), along with four known compounds (-) were isolated from Miq. Furthermore, the structure of the new compound was elucidated by the interpretation of spectroscopic data, including 1D and 2D-NMR, as well as ECD and NMR calculations (DP4+ analysis).

Appl Environ Microbiol
January 2025
Legume Rhizobium Sciences, Food Futures Institute, Murdoch University, Murdoch, Western Australia, Australia.
Unlabelled: Rhizobia are soil bacteria capable of establishing symbiosis within legume root nodules, where they reduce atmospheric N into ammonia and supply it to the plant for growth. Australian soils often lack rhizobia compatible with introduced agricultural legumes, so inoculation with exotic strains has become a common practice for over 50 years. While extensive research has assessed the N-fixing capabilities of these inoculants, their genomics, taxonomy, and core and accessory gene phylogeny are poorly characterized.

The number of high-quality genomes is rapidly increasing across taxa. However, it remains limited for coral reef fish of the Pomacentrid family, with most research focused on anemonefish. Here, we present the first assembly for a Pomacentrid of the genus .
