Groundbreaking microscopy unlocks secrets of plant virus assembly

New research into how a plant virus assembles could lay the groundwork for future use to carry drugs into the human body. The study, by a team from the University of Leeds’ Astbury Centre for Structural Molecular Biology and the John Innes Centre in Norwich, describes the structure of an empty version of Cowpea Mosaic Virus (CPMV) and the molecular “glue” that allows the virus to build itself and encapsulate its genome. The findings, published in the journal Nature Communications and based on revolutionary new electron microscopy, may be a crucial step to eventually allowing scientists to build custom versions of the virus that can carry medicines into the body and target disease.
