Polynucleotide constructs contain fiber-specific elements which are used to target expression of polynucleotides and polypeptides to the vascular fibers of a plant. The constructs can be contained within a vector. Transgenic plants transformed with the fiber-specific elements can be made which have expression of a polynucleotide or polypeptide directed to the plant fibers.

COMT1 gene fiber-specific promoter elements from poplar

The invention pertains to the genetically down regulating a lignin pathway p-coumarate Co-enzyme A ligase (CCL) in trees.

Genetic engineering of plants through manipulation of lignin biosynthesis

The present invention provides a Populus 4-coumarate Co-enzyme A ligase gene promoter that directs expression in the xylem of plants. The promoter is used in methods designed to alter lignin content, lignin structure, cellulose content and combinations thereof. The methods comprise operably linking said promoter to heterologous nucleic acid molecules.

4-coumarate co-enzyme a ligase promoter

The invention pertains to methods of altering growth, lignin content, coniferyl and sinapyl alcohol units in the lignin structure, disease resistance and cellulose content in plants by transformation with a lignin pathway p-coumarate Co-enzyme A ligase (4CL) nucleic acid.
