Abstract

Plants monitor environmental factors, such as temperature and day length, and also endogenous factors, such as their age and phytohormones, to decide when to flower. These cues are utilized to control expression levels of genes required for flowering. Thus, flowering time control is a unique model for understanding how gene activity is precisely regulated at the transcriptional level. In Arabidopsis, a remarkable number of non-coding RNA molecules have been identified by advanced sequencing technology. Recent progress in the flowering field has revealed several non-coding RNAs that play a major role in determining flowering time. Here, we introduce how two types of non-coding RNA species, microRNA miRNA and long noncoding RNA lncRNA, contribute to flowering via regulation of target gene activity involved in this vital developmental transition.
