Modification of plant resistance to diseases and/or pests

摘要

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.
