Exogenous application of RNAs as a silencing tool for discovering gene function.

Abstract

Abstract This chapter focuses on the importance of the RNA silencing technique in unraveling the function of genes by inhibiting gene expression at the post-transcriptional level, and is particularly appropriate for studying developmental processes such as fruit setting and growth that require a tight organ/tissue and time-specific regulation of the expression of target genes. Some methods used for establishing the function of a specific gene altering gene expression at either the genomic or post-transcriptional level are also presented.
