Abstract

Erysiphe graminis causes barley powdery mildew. Different races carry different avirulence (Avr) genes that enable the fungus to be recognised by plant carrying specific resistance genes. Avra12 and the gene cluster containing Avra9 and Avra22 have been genetically mapped and will be placed on a physical contig. Regions carrying the genes will be sequenced and molecular differences between virulent and avirulent isolates will be characterised. Candidate Avr genes will be tested by transforming virulent isolates and characterisation of the resulting phenotypes. Avr gene sequences, in conjunction with R gene sequences, will provide insight into the mechanism of gene-for-gene recognition of pathogens by plants.
