Plant RNA processing: discovery, mechanism and function

Abstract

Most classes of nascent plant primary RNAs must be modified or processed in various ways to be converted to their mature forms. RNA processing is the term collectively used to describe the series of events required to produce functional RNAs. During co-and post-transcriptional regulatory stages, RNA processing such as splicing, editing, 5´ capping, 3´-end polyadenylation, nucleolytic To present an overview of the fundamental discoveries related to the processing and modification of various classes of plant RNAs, which can generate new insights into the biological roles and underlying regulatory mechanisms of RNA processing in plant biological systems, the research topic of Frontiers in Plant Science on "Biological Roles of RNA Processing and its Regulations in Plants" presents 3 original research articles and 1 review report.The first article was on the roles of RNA splicing in the development of maize seed, the second one reported RNA editing´s impacts on rice drought tolerance, the third one identified lncRNAs that may be involved in rose floral scent synthesis, and the fourth one reviewed the production and regulation of miRNA in Arabidopsis thaliana.Maturases regulating RNA splicing play key roles in plant development.
