microRNAs in Arabidopsis : discovery, functions and roles in the control of flowering time

Discovered about 20 years ago, microRNA are small non-coding RNA (21-23 nt) involved in the post-transcriptional regulation of gene expression. They are involved in numerous regulatory pathways. However, the analysis of their function and their expression level is a bit tricky, explaining that they were only integrated in the molecular pathways during the last decade.

Here, we present a brief summary of the events that lead to the discovery of microRNAs, as well as the molecular tools used for their analysis and their role in the molecular control of flowering time.
