30.5.2017: Michael NODINE (Wien): MicroRNA functions in Arabidopsis embryos, Hörsaal 31.11, Institut für Pflanzenwissenschaften, Bereich Pflanzenphysiologie, Schubertstraße 51, um 17:00 Uhr. 

MicroRNAs (miRNAs) are a class of small regulatory RNAs that repress key developmental regulators and are essential for plant embryo development. Previously we found that miRNA-deficient embryos exhibit widespread differentiation defects and precociously express maturation-phase genes. This indicates that miRNAs are required for both embryonic pattern formation and the timing of the morphogenesis-to-maturation phase transition. Because plant miRNAs typically repress transcription factors and other key developmental regulators they likely have a large influence on the gene regulatory networks that control plant embryogenesis. Our major goal is to understand how miRNAs shape the gene regulatory networks that govern plant embryogenesis, and I will present our progress towards this aim.
