Advances in Research of Pathogenicity and Virulence Variation of the Wheat Stripe Rust FungusPuccinia striiformis f. sp.tritici
摘要
Abstract
Wheat stripe rust, caused by Puccinia striiformis West. f. sp.tritici Eriks. and Henn. (Pst), is an air-borne cryogenic fungal disease, which causes serious yield and economic losses and severely threatens the security of wheat production worldwide due to its wide transmission and high frequent epidemics. As an obligate parasitic pathogen, the rapid virulence variation of Pst leads to resistance breakdown of the existing resistant wheat cultivars, which then leads to the constant epidemic of the disease. Thus, the study on virulence variation mechanism of Pst has been paid much attention since 1950s. Until now, great efforts have been made and significant progress has been achieved. The progress in research of the disease made in recent years and the relationship between resistance breakdown of wheat cultivar and virulence variation, the variation ways of Pst pathogenicity, genetic structure analyses of Pst population and the molecular mechanism underlying the rapid virulence variation of Pst were summarized. Based on this review, the issues and challenges were put forward to accurately predict main predominant races, rationally use and distribute the resistance genes, and to create the new kind of disease-resistance materials through novel strategies, which will optimize and improve the comprehensive management system for wheat stripe rust, and help to realize the sustainable control of wheat stripe rust.关键词
