The use of cysteine proteinase inhibitors to engineer resistance against potyviruses in transgenic tobacco plants.

Nature biotechnology - 1 Dec 1999

Gutierrez-Campos R, Torres-Acosta J A, Saucedo-Arias L J, Gomez-Lim M A

Abstract excerpt

As the processing mechanism of all known potyviruses involves the activity of cysteine proteinases, we asked whether constitutive expression of a rice cysteine proteinase inhibitor gene could induce resistance against two important potyviruses, tobacco etch virus (TEV) and potato virus Y (PVY), in transgenic tobacco plants. Tobacco lines expressing the foreign gene at varying levels were examined for resistance...
