Discovery and characterization of a novel carlavirus in Ligularia jaluensis plants.

Ligularia jaluensis is an important medicinal and ornamental plant in China. However, the viruses capable of infecting Ligularia jaluensis remains unknown. Here, we identified a novel carlavirus, tentatively named ligularia jaluensis carlavirus (LJCV), as well as a known iris severe mosaic virus (ISMV), in L.

Two forms of phosphomannomutase in gammaproteobacteria: The overlooked membrane-bound form of AlgC is required for twitching motility of Lysobacter enzymogenes.

Lysobacter enzymogenes, a member of Xanthomonadaceae, is a promising tool to control crop-destroying fungal pathogens. One of its key antifungal virulence factors is the type IV pili that are required for twitching motility. Transposon mutagenesis of L.
