Abstract
The present invention relates to a method of modifying resistance of plants to disease and/or pests, through using the caffeic acid/caffeate O-methyltransferase (OMT) gene to modify lignin biosynthesis in plants. The preferred OMT gene is from ryegrass (Lolium perenne) or fescue (Festuca). The invention also relates to vectors useful in such methods, transformed plants with modified resistance to disease and/or pests, and plant cells, seeds and other parts of such plants.
Claims16
A method of increasing resistance to diseases and/or pests in a plant relative to an untransformed control plant, said method including introducing into said plant a nucleic acid selected from the group consisting of an O-methyltransferase homologue (OMTH) gene from a ryegrass (Lolium) or fescue (Festuca) species, said nucleic acid having a nucleotide sequence shown in FIG. 1 hereto (SEQ ID NO:
- 1), and functionally active fragments and variants thereof.
A vector capable of increasing resistance to diseases and/or pests in a plant, said vector including a nucleic acid selected from the group consisting of an OMTH gene from a ryegrass (Lolium) or fescue (Festuca) species, said nucleic acid having a nucleotide sequence shown in FIG. 1 hereto (SEQ ID NO:
- 1) and functionally active fragments and variants thereof.
