Abstract

Summary

Protoplasts derived from shoot cultures of potato cv. Cara, which carries immunity gene , 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 . 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.
