The Development of the Sexual Stage, Pathogenic Specialization and a Potential Means of Controlling the Urediniophase of Sunflower Rust, 'Puccinia helianthi' schw.
Sunflower rust caused by Puccinia helianthi is a major problem in sunflower production in Australia. The disease can be effectively controlled through the use of resistant hybrids but the commercial life of these is often short, due to the evolution of new pathotypes of the fungus. Since 1978,23 pathotypes have been recognised, mostly from commercial crops. Possible pathways for the evolution of these pathotypes are proposed. Almost all pathotypes identified since 1986 trace to a common progenitor, Aus4. Avirulence/virulence patterns of many pathotypes suggest that sexual recombination may be acting to generate new pathotypes, but the sexual stages of the fungus are rarely seen in the field. It is assumed that bursts of evolution occur in seasons that favour completion of the sexual cycle, and that mutation contributes steadily to the development of new virulence genes in the population of P helianthi.
