The Ins and Outs of Multipartite Plant Viruses

Viruses possessing a non-segmented genome require a specific recognition of their nucleic acid to ensure its protection in a capsid. A similar feature exists for viruses having a segmented genome, usually consisting of viral genomic segments joined together into one … Continue reading

How soil bacteria escape sticky root traps

Plant root tips are covered by a protective sleeve of loosely attached border cells that can release a matrix containing proteins, polysaccharides, and DNA. In animal immune systems, extracellular DNA forms the backbone of neutrophil extracellular traps (NETs) deployed by … Continue reading

Plant virus RNA silencing suppressor proteins

The RNA silencing pathway in plants acts in part as an antiviral defense mechanism. Plant viruses have evolved to encode suppressors of RNA silencing. Plant viral RNA silencing suppressor proteins (RSS) show little sequence conservation, but act on similar key … Continue reading
