The Role of Allopatry and Sympatry in Reproductive Barriers and Plant Pathogen Speciation

通过整合基因组、表型和地理数据，这项研究推进了对生殖和交配障碍知之甚少的植物病原体物种形成的知识。其目的是(1)检查感染所涉及的基因组的结构差异是否导致合子后隔离；(2)确定异位和共生对生殖障碍和发病机制差异的贡献；(3)建立交配交叉论文来研究配对和合子后障碍和强化。这项研究的创造性包括(1)将植物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的迁移是否与物种形成所涉及的不同生殖障碍相一致；(3)通过观察雌性结构的行为来直接测试配偶选择。结果可以改变病原体物种形成领域，在那里生殖和交配障碍在很大程度上未经测试，并且处于不同的生物组织水平。这项研究的发现不仅将加强对植物病原体进化的理解，还将对微生物学(真菌学)和普通病理学的其他领域做出贡献。

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.
