Kaposi’s sarcoma-associated herpesvirus ORF57 protein protects viral transcripts from specific nuclear RNA decay pathways by preventing hMTR4 recruitment

 Our skin and mucosal surfaces are colonized by diverse microbial communities, collectively known as the microbiota. Litvak & Bäumler argue that investment in research on the mechanistic underpinnings of priority effects will greatly enhance our understanding of how host-associated microbial communities function during health and disease and usher in an era of mechanistic microbiota research.

Most plant viruses are vectored by insects and the interactions of virus-plant-vector have important ecological and evolutionary implications. Li et al.'s results demonstrate that ubiquitination inhibition by begomovirus C2 protein might be a general mechanism in begomovirus, whitefly and plant interactions.
