Mutations in viral movement protein alter systemic infection and identify an intercellular barrier to entry into the phloem long-distance transport system.

Abstract excerpt

Viral systemic infection of a plant host involves two processes, cell-to-cell movement and long-distance transport. Molecular determinants associated with these two processes were probed by investigating the effects that alanine scanning mutations in the movement protein (MP) of red clover necrotic mosaic virus (RCNMV) had on viral infection in the plant hosts Nicotiana edwardsonii, Vigna unguiculata (cowpea),...
