Identifying protein-DNA interactions involved in wood development in poplar

Trees are unique among plants since they have extremely long life spans and have the ability to generate large quantities of woody biomass resulting from the formation of secondary xylem formed by the vascular cambium. The composition of xylem and the arrangement of cell types determine the physical and structural properties of wood. Gene-specific transcription factors (TFs) are DNA-binding regulatory proteins capable of either activation or repression by binding to a specific region of DNA, normally located in the 5-prime upstream region of the gene. These Protein-DNA interactions are responsible for gene expression during plant growth and development. One method for altering lignin composition is by manipulation of TFs involved in lignin biosynthesis.
