Coat protein-independent cell-to-cell movement of bromoviruses expressing brome mosaic virus movement protein with an adaptation-related amino acid change in the central region.

Abstract excerpt

The movement protein (MP) of Brome mosaic virus (BMV) depends on the coat protein (CP) to mediate the cell-to-cell movement of BMV and CCMV(B3a), a recombinant Cowpea chlorotic mottle virus (CCMV) expressing BMV MP. Previous studies identified gain-of-function mutations in the central region of BMV MP that enable CCMV(B3a) to adapt to a resistant host. This study demonstrates that all adaptation-related MPs can...
