Heterologous encapsidation of potato virus Y strain O (PVYO), with the transgenic coat protein of PVY strain N (PVYN) in Solanum tuberosum cv. Bintje

Heterologous encapsidation of potato virus Y strain O (PVYO), with the transgenic coat protein of PVY strain N (PVYN) in Solanum tuberosum cv. Bintje

Bio/Technology 10(9): 1020-1025

Potato plants transgenic for the coat protein (CP) gene of potato Y potyvirus strain N (PVYN) were examined for the accumulation of the transgenic PVYN CP. The protein remained undetectable in healthy plants of lines Bt6 and Bt10 that are completely or partially resistant to this virus, but accumulated when the plants were infected by a related strain, PVYO. One possible explanation was that the transgenic CP is stabilized by integration into the capsid of the infecting virus.
