Abstract: The present invention relates to the modification of lignin biosynthesis in plants, to enzymes involved in the lignin biosynthetic pathway and nucleic acids encoding such enzymes and, more particularly, to methods of modifying lignin biosynthesis via sense suppression and to related nucleic acids and constructs.

Abstract: The present invention provides nucleic acid molecules derived from Nicotiana alata, which encode defensin-like molecules. The present invention contemplates the use of such nucleic acid molecules in the generation of transgenic plants having resistance or at least reduced sensitivity to plant pests including insects, microorganisms, fungi and/or viruses and the of the encoded defensin-like molecules in compositions for topical application to a plant or a plant part so as to reduce prevent or reduce infestation of the plant or plant part by plant pests. The transgenic plants provided by the present invention include monocotyledonous and dicotyledonous plants, and particularly include crop plants and ornamental flowering plants.

Abstract: Provided is a system for protecting plants from attack by pests, including pathogens such as fungi. Specifically, a plant defensin is provided in conjunction with a protease inhibitor protects a plant from pest attack or reduces severity of an attack.

Abstract: A multigene expression vehicle (MGEV) consisting essentially of a polynucleotide comprising 2 to 8 domain segments, D, each domain encoding a functional protein, each domain being joined to the next in a linear sequence by a Linker (L) segment encoding a Linker peptide, the D and L segments all being in the same reading frame, and at least one of the domains is not a type two protease inhibitor.

Abstract: The present invention relates generally to a novel chymotrypsin that exhibits resistance to a plant serine proteinase inhibitor. More particularly, the present invention provides a chymotrypsin which is up-regulated in the gut of Helicoverpa armigera and Helicoverpa punctigera insect larvae when fed the serine proteinase inhibitors of Nicotiana alata. The novel chymotrypsin represents, therefore, a target for the identification of antagonists including inhibitors which are proposed to be useful in the control of Helicoverpa spp. populations that have become resistant to serine proteinase inhibitors produced in plants. The antagonists of the chymotrypsin may be topically applied to the plants or, when in proteinaceous form, may be produced by genetic means in plant cells. The antagonists may act at the level of gene expression or protein activity.
