| Summary, etc. |
Avirulence (Avr)genes exist in many fungi that share a gene-for-gene relationship with their host plant. They represent unique genetic determinants that prevent fungi from causing disease on plants that possess matching resistance (R)genes. Interaction between elicitors (primary or secondary products ofAvrgenes)and host receptors in resistant plants causes induction of various defense responses often involving a hypersensitive response.Avrgenes have been successfully isolated by reverse genetics and positional cloning. Five cultivar-specificAvrgenes (Avr4,Avr9, andEcp2 fromCladosporium fulvum; nip1fromRhynchosporium secalis;andAvr2-YAMOfromMagnaporthe grisea)and three species-specificAvrgenes (PWL1andPWL2fromM. griseaandinf1fromPhytophthora infestans)have been cloned. Isolation of additionalAvrgenes from these fungi, but also from other fungi such asUromyces vignae,Melampsora lini, Phytophthora sojae,andLeptosphaeria maculans,is in progress. Molecular analyses of nonfunctionalAvrgene alleles show that these originate from deletions or mutations in the open reading frame or the promoter sequence of anAvrgene. Although intrinsic biological functions of mostAvrgene products are still unknown, recent studies have shown that twoAvrgenes,nip1andEcp2, encode products that are important pathogenicity factors. All fungalAvrgenes cloned so far have been demonstrated or predicted to encode extracellular proteins. Current studies focus on unraveling the mechanisms of perception of avirulence factors by plant receptors. The exploitation ofAvrgenes and the matchingRgenes in engineered resistance is also discussed. |
