The leaf surface, known as the phylloplane, presents an oligotrophic and heterogeneous environment due to its topography and uneven distribution of resources. Although it is a challenging environment, leaves support abundant bacterial communities that are spatially structured. However, the factors influencing these spatial distribution patterns are not well understood.

A polyphasic taxonomic study was carried out on strain T5W1, isolated from the roots of the aquatic plant . This isolate is Gram-negative, rod-shaped, motile, aerobic and non-pigmented. Nearly complete 16S rRNA gene sequence homology related the strain to , with 98.

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).
