Virus-Induced Gene Silencing as a Tool to Study Tomato Fruit Biochemistry
Virus-Induced Gene Silencing (VIGS) is an excellent reverse genetic tool for the study of gene function in plants, based on virus infection. In this chapter, we describe a high-throughput approach based on VIGS for the study of tomato fruit biochemistry. It comprises the selection of the sequence for silencing using bioinformatics tools, the cloning of the fragment in the Tobacco Rattle Virus (TRV), and the agroinfiltration of tomato fruits mediated by Agrobacterium tumefaciens.
