Eight adaptive mutant clones have been made from the total RNA extracted from uninoculated upper leaves of a single cowpea plant exhibiting systemic infection after inoculation with a hybrid cowpea chlorotic mottle bromovirus (CCMV) with the 3a movement protein gem of CCMV replaced by that of cowpea-nonadapted brome mosaic bromovirus (BMV). Sequence and mutational analyses of these clones showed genotypic and phenotypic diversity of the cloned virus population, but all examined clones had the adaptive mutation, A to C at position 776 within the BMV 3a gene, required for the systemic infection of cowpea. The data support the quasispecies model for RNA virus population, and suggest that the maintenance of the adaptive mutation may be due to powerful selection pressure in an infection process.
