Virus-induced gene silencing (VIGS) is a functional genomics tool to transiently downregulate the expression of target gene(s) by exploiting the plant's innate defense mechanism against invading RNA viruses. VIGS is a rapid and efficient approach to analyze the gene function, particularly, in the plants that are not amenable to stable genetic transformation. This strategy has been successfully used to decipher the function of several genes and transcription factors involved in the biosynthesis of specialized metabolites and regulation of specialized metabolism, respectively, in different medicinal and aromatic plants. Here, we describe a detailed Tobacco rattle virus (TRV)-mediated VIGS protocol for silencing of the gene encoding Phytoene desaturase (PDS) in important medicinal plants Catharanthus roseus, Calotropis gigantean, Rauwolfia serpentina, and Ocimum basilicum. Our methods allow the study of gene function within 3-4 weeks after agro-inoculation, and can be an easy and efficient approach for future studies on understanding of the biosynthesis of specialized metabolites in these important medicinal plants. |
