Abstract

Highlights: Multiple tiers of post-transcriptional and post-translational regulation control diverse developmental processes in plants. RBP-mediated regulation of RNA metabolism and translation provides developmental plasticity in response to environmental challenges. Cell type-specific and developmental process-specific insights into RNA metabolism and translation will continue to uncover the multifaceted roles of RBPs. Abstract : RNA-binding proteins (RBPs) influence the fate of target RNAs via direct interactions. During transcription, RBPs and interacting partners are recruited to and modify transcripts, after which they may also participate in critical steps to generate functional RNA. RBP–RNA interactions govern post-transcriptional processing of RNA, consequently regulating gene expression in a spatio-temporal manner. In plants, an increasing number of proteins have been classified as RBPs, many of which have been shown to function as key players in diverse developmental processes. However, a comprehensive understanding of how RBPs function, which RNAs are targeted, and where RBP–RNA interactions occur within plant cells is lacking. Here, we discuss recent findings in the field and newly defined roles for RBPs in plant growth and development. We also describe the mechanistic effects of RBPs on target RNA metabolism and translation.
