摘　　要：Stripe (yellow) rust caused by Puccinia striiformis f. sp. tritici occurs in almost allwheat-producing regions of the world. Severe countrywide epidemics in Chinahave caused substantial yield losses. Growing resistant cultivars is the beststrategy to control this disease but the pathogen can overcome resistance inwheat cultivars. The high variation in the virulence of the pathogen combinedwith the large areas of susceptible wheat cultivars enables the pathogenpopulation to increase rapidly and disperse over long distances under favorableenvironmental conditions, resulting in severe pandemics within croppingseasons. Current stripe rust control measures are based on many years ofresearch including the underlying epidemiology regarding year-to-year survivalof the pathogen, pathways of pathogen dispersal within seasons and years, therole of P. striiformis sexual hybridization, the use of resistance sources inbreeding programs, and year-round surveillance of national wheat crops that arepresent in different parts of the country throughout the year. All these strategiesdepend on accurate prediction of epidemics, more precise use of fungicides tomeet national requirements and better deployment of resistance genes. Newideas with potential application in sustainable protection of stripe rust includenegative regulatory gene editing, resistance gene overexpression and biologicalcontrol based on microbiomes.
