Tobamovirus and dianthovirus movement proteins are functionally homologous.

Abstract

The movement proteins (MPs) of tobacco mosaic tobamovirus (TMV) and red clover necrotic mosaic dianthovirus (RCNMV) enlarge plasmodesmata size exclusion limits, transport RNA from cell to cell, and bind nucleic acids in vitro. Despite these functional similarities, they have no sequence homology. However, they do appear to have similar secondary structures… (More)
