Plant vascular tissues play essential roles in plant growth and development, and have allowed plant species to successfully adapt to a variety of environments since they evolved 450 Mya. Furthermore, as the major component of vascular tissue, xylem forms the majority of plant biomass on the earth’s surface. The search for environmentally friendly bioenergy has made the biosynthesis of plant biomass one of the most important research topics in plant biology. The long term goal of research in the Wang Lab is to elucidate the molecular mechanisms in regulating plant vascular development and xylem differentiation.
Plant vascular tissues are composed of xylem, phloem and the intervening vascular stem cells (AKA procambium or cambium). Stem cells produce progeny cells, which either maintain their stem cell property or differentiate into xylem toward the center and phloem toward the periphery of plant stems. Compared to stem cells in the shoot apical meristem (SAM) and root apical meristem (RAM), we know little about the maintenance of vascular stem cells. We have identified several transcriptional regulators that function in vascular patterning and stem cell maintenance in Arabidopsis. Dissecting the molecular mechanisms of these regulators will provide new insights in plant stem cell maintenance.
Xylem tissues develop secondarily thickened cell walls and form the majority of terrestrial cellulosic biomass. Our research focus on how cells with secondary cell walls (SCWs) differentiate; how syntheses of the three cell wall components, e.g. cellulose, lignin and hemicelluloses, are coordinately regulated; and how to apply our findings to improve feedstock properties for biofuel production. We use Arabidopsis and poplar trees as model plants to investigate transcription factors and their networks in regulating SCW deposition. We have elucidated the functions of microRNAs, class III HD-ZIP TFs, NAC and WRKY domain TFs in SCW development. Genetics, biochemistry, genomics and molecular biology approaches are used in the lab to decipher regulatory mechanisms of the biological pathways.
