Abstract
Disclosed herein are viral vectors suitable for transfection into woody trees for purposes of delivering and expressing beneficial genes. Specifically exemplified herein are vectors for transfecting citrus trees. The vectors allow for the expression of useful proteins, such as those that can protect the tree from disease. Specifically exemplified herein are methods of transfecting woody trees that allow multiple applications of vectors while avoiding superinfection exclusion.
Claims1
A citrus tristeza virus (CTV) vector from a CTV strain T36 engineered to have an endogenous leader protease region comprising L1L2 leader protease sequence substituted with a cognate region comprising L1L2 leader protease sequence from an isolate of T68 strain of CTV, and wherein said CTV engineered vector is further engineered to comprise an expressible heterologous gene sequence.
