Abstract

The aim is to clone avirulence genes from the barley mildew pathogen, Erysiphe graminis f. sp. hordei (Egh). A genetic map of a cross in which eight avirulence genes segregate will be constructed using amplified fragment length polymorphisms (AFLPs). Next, a high resolution AFLP map of the regions around the Avra131 and Avra132 loci will be made. Cosmid contigs covering these loci will be developed, using flanking AFLPs, and sub-cloned into plasmids. The presence of avirulence genes in these contigs will be tested, if possible by transforming isolates virulent on Mla13 barley to avirulence or, alternatively, by comparative analysis of cDNA libraries from barley infected with virulent or avirulent isolates.
