Expression of potato virus x resistance gene rx in potato leaf protoplasts

Expression of potato virus x resistance gene rx in potato leaf protoplasts

Journal of General Virology 67(1): 2341-2346

Protoplasts derived from shoot cultures of potato cv. Cara, which carries immunity gene Rx, supported only limited virus multiplication after inoculation with particles or RNA of isolate DX, a group 3 strain of potato virus X, as compared to similarly inoculated protoplasts of cultivars King Edward and Pentland Ivory which lack Rx. The Cara protoplasts were, however, able to support extensive replication of the resistance-breaking strain HB. This strain-specific resistance did not appear to be mediated by a failure or inhibition of the uncoating mechanism or of virus assembly.
