By integrating genomic, phenotypic, and geographic data, this research advances knowledge of plant pathogen speciation in which little is known about reproductive and mating barriers. The objectives are to (1) examine if structural differences in the genome involved in infection result in postzygotic isolation; (2) determine the contribution of allopatry and sympatry to reproductive barriers and differences in pathogenesis; (3) establish mating cross essays to study premating and postzygotic barriers, and reinforcement. The creative qualities of the research involves (1) integrating theories in plant pathology on genome architecture with speciation theory; (2) identifying if human-mediated migration of plant pathogens coincide with the different reproductive barriers involved in speciation; and (3) directly testing for mate selection by observing the behavior of female structures. Results can transform the field of pathogen speciation where reproductive and mating barriers have largely been untested and at different levels of biological organization. Not only will findings from this research enhance the understanding of plant pathogen evolution but will contribute to other fields in microbiology (mycology), and general pathology.

通过整合基因组，表型和地理数据，这项研究进展的知识，植物病原体物种形成，很少有人知道生殖和交配障碍。其目的是（1）检查是否在感染的基因组结构差异导致合子后隔离;（2）确定异地和同域的贡献，生殖障碍和发病机制的差异;（3）建立交配杂交试验，研究交配前和合子后的障碍，并加强。该研究的创造性品质包括：（1）将植物病理学中关于基因组结构的理论与物种形成理论相结合;（2）确定人类介导的植物病原体迁移是否与物种形成中涉及的不同生殖障碍相一致;（3）通过观察雌性结构的行为直接测试配偶选择。这些结果可以改变病原体物种形成的领域，其中生殖和交配障碍在很大程度上未经测试，并在不同层次的生物组织。这项研究的发现不仅将增强对植物病原体进化的理解，而且将有助于微生物学（真菌学）和普通病理学的其他领域。
