The present disclosure relates to the development and use of Closterovirus-based vectors for the delivery of nucleotides to plants. Specifically, the present disclosure provides viral vectors based on Grapevine leafroll-associated virus-2 for the delivery and expression of genes in plants, particularly grape plants. Methods of making and using these vectors, as well as the plants transformed by these vectors, are also contemplated.

Closterovirus vectors and methods

The present invention provides an expression vector adapted for expressing heterologous proteins in plants susceptible to a polyprotein-producing plant virus. The vector utilizes the unique ability of viral polyprotein proteases to cleave heterologous proteins from viral polyproteins. Also provided is a method for expressing heterologous proteins in plants using these unique expression vectors.
