Regulation of flowering time by RNA processing.
Plants control the time at which they flower by integrating environmental cues such as day length and temperature with an endogenous program of development. Flowering time is a quantitative trait and a model for how precision in gene regulation is delivered. In this review, we reveal that flowering time control is particularly rich in RNA processing-based gene regulatory phenomena. We review those factors which function in conserved RNA processing events like alternative 3' end formation, splicing, RNA export and miRNA biogenesis and how they affect flowering time. Likewise, we review the novel plant-specific RNA-binding proteins identified as regulators of flowering time control. In addition, we add to the network of flowering time control pathways, information on alternative processing of flowering time gene pre-mRNAs. Finally, we describe new approaches to dissect the mechanisms which underpin this control.
