| 摘要 |
The present invention relates to the modification of lignin biosynthesis in plants, using the nucleotide sequences encoding the enzymes 4-coumarate CoA-ligase (4CL), cinnamoyl-CoA reductase (CCR), cinnamyl alcohol dehydrogenase (CAD) of the lignin biosynthetic pathway, from ryegrass (Lolium) and fescue (Festuca). The present invention also relates to regulatory elements, promoters capable of causing expression of exogenous genes in plants, wherein the regulatory elements are from the genes for caffeic acid Omethyl transferase (OMT), 4CL, CCR or CAD. The invention also relates to vectors including the nucleic acids and regulatory elements of the invention, plant cells, plants, plant seeds and other plant parts transformed with the regulatory elements, nucleic acids and vectors and methods using the nucleic acids, regulatory elements and vectors.
