Virus-Induced Gene Silencing (VIGS) in Chili Pepper (Capsicum spp.)

Methods Mol Biol. 2020:2172:27-38. doi: 10.1007/978-1-0716-0751-0_3.

Abstract

Virus-induced gene silencing (VIGS) is a transcript suppression technique that enables the functional characterization of genes in recalcitrant transformation plants. This technique consists in cloning a short fragment of a gene of interest into a viral vector, such as TRV (Tobacco rattle virus), and this viral construction is used to agro-infiltrate the plant. VIGS induces posttranscriptional gene silencing (PTGS) that results in the specific sequence degradation of target RNAs. Here we describe a VIGS protocol using the Gateway-based TRV vector for the study of genes in chili pepper plants.
