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 present invention provides, inter alia, a B.t. hybrid toxin fragment comprising at its C-terminus domain III of a first Cry protein, or a part of said domain or a protein substantially similar to said domain; and comprising at its N-terminus the N-terminal region of a second Cry protein, or a part of said region or a protein substantially similar to said region.
摘要:
A recombinant polynucleotide which can be used for obtaining a male-sterile plant comprising an inhibitor gene capable of inhibiting the expression of a target gene encoding MS2 protein or a homologous target gene and a promoter that is active in the tapetum. A method for obtaining male-sterile plants. Cells, fruit, seeds and progeny of male-sterile plants are also described.
