Research Interests
Sexual reproduction in higher plants is composed of multiple biological processes including gametogenesis, male-female interactions, fertilization and embryogenesis, which are under tight genetic regulation. Taking dicotyledous model plant Arabidopsis thaliana as research materials, we aim to dissect the molecular regulation mechanisms involved in plant reproduction by using combinations of genetic, biochemical and molecular biology approaches. We are mainly interested in three categories of the regulatory factors involved in plant reproduction: 1) receptor-like protein kinases/peptide signals-mediated signaling pathways; 2) factors regulating protein degradation and/or endomembrane trafficking; 3) transcription factors. We are also interested in developing new tools for genetic editing in plants.
