| population genetic analysis of an eastern u.s. wheat powdery mildew population reveals geographic subdivision and recent common ancestry with u.k. and israeli populations. | the structure of the u.s. wheat powdery mildew population (blumeria graminis f. sp. tritici) has not been previously investigated, and the global evolutionary history of b. graminis f. sp. tritici is largely unknown. after gathering 141 single-ascosporic b. graminis f. sp. tritici isolates from 10 eastern u.s. locations, 34 isolates from the united kingdom, and 28 isolates from israel, we analyzed pathogen population structure using presumptively neutral markers. dna was extracted from conidia, ... | 2009 | 19522582 |
