Small RNA functions in plant embryos
The basic plant body plan is established during embryogenesis. However, despite its fundamental importance to both agriculture and developmental biology, the molecular mechanisms that regulate plant embryogenesis remain mostly uncharacterized. Studying the embryonic functions of regulatory RNAs will not only yield significant insights into the mechanistic basis of plant embryo development, but will also contribute to our general understanding of how regulatory RNAs influence cellular differentiation. For example, a class of ~21 nucleotide RNAs called microRNAs (miRNAs) play essential roles during plant embryo pattern formation and developmental timing. Interestingly, most plant embryonic miRNAs repress transcripts encoding transcription factors and other key developmental regulators. Our goal is to understand how small regulatory RNAs, including miRNAs, shape the gene regulatory networks that control plant embryogenesis. We will use a combination of cutting-edge experimental and computational approaches to achieve this aim.
