Title	Genetic control of responsiveness of wheat to elicitors in intercellular washing fluids from leaf rust-infected leaves
Journal	Physiology and Molecular Plant Pathology
Year	1994
Volume	45
Pages	189-194
Author	Deverall B Saverimuttu N Cantrill L McIntosh R
Abstract	Reciprocal crosses were made between the cv Cappelle Desprez, which is highly responsive to elicitors in intercellular washing fluids from leaf rust-infected leaves, and the non-responsive cv Little Club Analyses of F2 and F3 generations showed that responsiveness was conferred by a single dominant gene Studies of recombinant lines for chromosome 5A and its long arm from Cappelle Desprez indicated that the gene must be located in the long arm of 5A It is proposed that the gene encodes for a receptor of the elicitors which are considered to be glycoprotein(s) from the walls of rust fungi. The action of the gene for expression of resistance is observed when the elicitors are introduced into the intercellular spaces but not during infection by the rust hyphae, suggesting that the elicitors on fungal walls are not presented to the receptor in the normal infection process.
