Abstract

Abstract: Reverse genetics approaches are routinely used to investigate gene function. However, mutations, especially in critical genes, can lead to pleiotropic effects as severe as lethality, thus limiting functional studies in specific contexts. Approaches that allow for modifications of genes or gene products in a specific spatial or temporal setting can overcome these limitations. The advent of CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) technologies has not only revolutionized targeted genome modification in plants but also enabled new possibilities for inducible and tissue-specific manipulation of gene functions at the DNA and RNA levels. In addition, novel approaches for the direct manipulation of target proteins have been introduced in plant systems. Here, we review the current development in tissue-specific and conditional manipulation approaches at the DNA, RNA, and protein levels.
