摘要:
A method of protecting a plant or part of a plant from insect or nematode infestation is disclosed herein. The method includes the steps of: inserting into the genome of cells or tissue from a plant a sequence coding for equistatin operably linked to a promoter sequence active in the plant to cause expression of the protein at levels which provide an insect or nematode controlling amount of the protein; and regenerating resistant whole plants from the cells or tissue. Also disclosed is a transgenic plant or its sexual progeny which is resistant to attack by one or more insects or nematodes having digestive cysteine proteases. Also disclosed is an expression vehicle that includes a promotor effective to promote expression of a downstream coding sequence in plant cells, the expression vehicle being effective to express in plant cells insect controlling amounts of equistatin.
摘要:
The invention relates to the field of genetic engineering of flavor, fragrance and biocontrol agent development. More specifically it relates to a process for production of natural flavors, fragrances or bio-control agents by the control of one or more genes implicated in that process. The invention provides an isolated or recombinant nucleic acid or functional fragment thereof encoding a proteinaceous molecule essentially capable of flavor, fragrance and/or bio-control agent synthesis when provided with a suitable substrate under appropriate reaction conditions. The invention further provides a nucleic acid or functional fragment thereof encoding a proteinaceous molecule essentially capable of synthesizing at least a monoterpene alcohol linalool when contacted with geranyl diphosphate (GPP) and/or at least a sesquiterpene alcohol nerolidol when contacted with farnesyl diphosphate (FPP) under appropriate reaction conditions.
