Abstract
A method for obtaining plants with reduced susceptibility to invasion by a plant parasitic nematode, and plants having reduced susceptibility to invasion by a plant parasitic nematode obtained, for example, with such method. The method includes the following steps: (a) transforming cells of a plant or progeny of the plant with a coding sequence A and a coding sequence B, the coding sequences A and B being selected such that transformed cells expressing the coding sequences A and B display a normal phenotype and such that a nematode feeding structure comprising a cell expressing the coding sequence A but not expressing the coding sequence B has a reduced ability to support development of the plant parasitic nematode as compared with a nematode feeding structure wherein coding sequence A is not expressed, the coding sequence A being under the control of a promoter A that drives expression of the coding sequence A preferentially in the cell of the nematode feeding structure, the coding sequence B being under the control of a promoter B that drives expression of the coding sequence B in transformed cells wherein coding sequence A is expressed but not in the cell of the nematode feeding…
