Abstract
The invention relates to the use for control of Homopteran insect pests of a protein which has toxic or antimetabolic effects on them. According to the invention there is provided a transgenic plant comprising a gene coding for a protein which has toxic or antimetabolic effects on Homopteran insect pests, the gene being associated with a promoter which causes the gene to express the protein in the phloem of the plant.
Claims8
A method of controlling Homopteran insect pests, which comprises administering enterally to the pests a protein which has toxic or antimetabolic effects on them, the protein being expressed in the phloem of a transgenic plant comprising a gene coding for the protein, the gene being associated with a phloem specific promoter which causes the gene to express the protein in the phloem of the plant.
A method according to 1, wherein the promoter is selected from the group consisting of the 4.times.B2+A promoter, the rice sucrose synthetase gene promoter and the oilseed rape extensin gene promoter.
