The barley leaf rust resistance gene Rph3 encodes a predicted membrane protein and is induced upon infection by avirulent pathotypes of Puccinia hordei

Abstract

Leaf rust is an economically significant disease of barley. Here the authors describe cloning of the barley Rph3 leaf rust resistance gene and reveal it encodes a predicted transmembrane protein that is expressed upon infection by Rph3-avirulent Puccinia hordei isolates.
