Abstract

Early debut for microRNAs RNA interference (RNAi) has emerged as an important regulatory mechanism in which very short RNAs are used to silence gene expression. Because small RNAs had been found in only multicellular organisms, it had been proposed that RNAi evolution was driven by the need to regulate expression of genes in different tissues or at different developmental stages. But that idea has not lasted long. Two recent papers, one published in this issue, report the presence of both microRNAs and short interfering RNAs in the unicellular alga, Chlamydomonas. This finding suggests that the complex RNA silencing systems had evolved well before the advent of multicellualar organisms.
