Genetic diversity and population structure of Puccinia striiformis f. sp. tritici reveal its migration from central to eastern China

This study focused on Puccinia striiformis f. sp. tritici (Pst), the causal pathogen of wheat stripe rust in China. The central and eastern China are the main wheat-producing areas in the country, and the occurrence of wheat stripe rust can cause severe yield losses. To determine the population genetic structure and potential pathways of migration among regional populations of the pathogen, 264 isolates were sampled during spring 2017 and...
