Fungicide Application on Alternate Host Barberry Has Significant Roles in Declining Population Genetic Diversity and the Risk of Emerging New Races of Puccinia striiformis f. sp. tritici.

Abstract excerpt

Puccinia striiformis f. sp. tritici (Pst) is a destructive pathogen renowned for its dual reproductive modes, an asexual stage on wheat and a sexual stage on barberry (Berberis), which makes wheat cultivars vulnerable to newly emerging races. However, little has been known about the impact of treatment on barberry plants on declining population genetic diversity and race composition. In this study, we selected...
