Evolution of bamboo mosaic virus in a nonsystemic host results in mutations in the helicase-like domain that cause reduced RNA accumulation.

Abstract excerpt

A mutant population of bamboo mosaic potexvirus (BaMV) was isolated after serial passage using Chenopodium quinoa plants. While the wild type inoculum induced indistinct chlorotic lesions, the mutant produced obvious lesions on C. quinoa although RNA accumulation of the mutant in Nicotiana benthamiana protoplasts was significantly reduced compared to wild type. Mutations were identified in the helicase-like...
