TISSUE-SPECIFIC POPLAR PROMOTERS

摘要

The invention concerns the isolation and characterization of DNA sequences representing a caffeoyl-CoA-O-methyltransferase (CCoAOMT) promoter having a biological activity in at least one plant or tree vessel and/or in cells adjacent to said vessel or vessels. The cells adjacent to the vessel are xylem ray cells whereas the vessel can be a differentiating vessel.
