Abstract excerpt
Clonal reproduction in Puccinia triticina, the cause of wheat leaf rust, has long been hypothesized but has never been demonstrated. Using a population genetics approach and microsatellite markers, we analysed genetic diversity of this fungus at each level of genome organisation. Sampling included isolates from two field populations growing on two cultivars carrying specific resistance genes, completed with...
