项目摘要

This action funds an NSF Postdoctoral Research Fellowship in Biology for FY 2020, Broadening Participation of Groups Under-represented in Biology. The fellowship supports a research and training plan for the Fellow that will increase the participation of groups underrepresented in biology. The Fellow will conduct research on the interactions between jimson weed (Datura wrightii) and tobacco hornworms (Manduca sexta) and receive training in bioinformatics techniques. The research project will generate a wealth of genetic data on species of interest that can be used by the Fellow, future students, and the field of evolutionary genetics to generate and test hypotheses regarding the evolution of plant-insect interactions. One of these species is a major crop pest, thus, this research will also contribute to the development of novel pest-control methods. The Fellow will engage in outreach activities with Native American communities and students, to exchange modern and traditional agricultural practices with Native American communities on multiple reservations throughout Arizona in addition to providing Native students with hands-on research experience. The Fellow will work towards two research goals: 1) produce a high-quality reference genome for D. wrightii for comparison of that to M. sexta, and 2) re-sequence individuals of both species from across the Southwest to conduct a population genomics analysis of the coevolutionary dynamics. In comparing the reference genomes of D. wrightii and M. sexta the Fellow will test for the presence of synchronized gene duplication events, a molecular signature of antagonistic coevolutionary history. The approach used in the second objective will allow the Fellow to distinguish among four coevolutionary models of mutualism – mutual matching, sanctions, partner fidelity feedback, and signaling and recognition – to understand if and how mutualistic coevolution between D. wrightii and M. sexta has shaped their interactions. Together, these results will illuminate the relative importance of antagonistic and mutualistic pressures in shaping plant-insect interactions. It is possible for both forms of coevolution to act simultaneously, individually, or not act in this system (if traits evolved in response to other environmental pressures). As such, this study will provide broad insights into the coevolutionary dynamics of a multifaceted plant-insect interaction. The impact of the work will be broadened through student mentoring, and public and educational outreach through programs that serve Native American students and communities.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
这项行动资助了2020财年的NSF生物学博士后研究奖学金,扩大了生物学中代表性不足的群体的参与。该研究金支持研究员的一项研究和培训计划,该计划将增加在生物学领域代表性不足的群体的参与。该研究员将研究曼陀罗(Datura wrightii)和烟草角虫(Manduca sexta)之间的相互作用,并接受生物信息学技术培训。该研究项目将产生丰富的感兴趣物种的遗传数据,可用于研究员,未来的学生和进化遗传学领域,以生成和测试关于植物-昆虫相互作用进化的假设。其中一种是主要的农作物害虫,因此,这项研究也将有助于开发新的害虫控制方法。该研究员将与美国原住民社区和学生开展外联活动,与亚利桑那州各地的多个保留地的美国原住民社区交流现代和传统农业实践,并为原住民学生提供实践研究经验。 该研究员将致力于两个研究目标:1)为D。wrightii与M. sexta,和2)重新排序来自西南部的两个物种的个体,以进行共同进化动态的群体基因组学分析。在比较D. wrightii和M. Sexta研究员将测试同步基因复制事件的存在,这是对抗性共同进化历史的分子标志。在第二个目标中使用的方法将允许研究员区分互利主义的四种共同进化模型-相互匹配,制裁,伙伴忠诚反馈,以及信号和识别-以了解D之间是否以及如何互利主义共同进化。wrightii和M. sexta塑造了他们的互动。总之,这些结果将阐明在塑造植物-昆虫相互作用的拮抗和互利的压力的相对重要性。这两种形式的共同进化有可能同时单独行动,或者在这个系统中不行动(如果性状是为了应对其他环境压力而进化的)。因此,这项研究将为多方面的植物-昆虫相互作用的共同进化动力学提供广泛的见解。这项工作的影响将通过学生指导,以及通过服务于美国原住民学生和社区的计划扩大公众和教育推广。该奖项反映了NSF的法定使命,并通过使用基金会的智力价值和更广泛的影响审查标准进行评估,被认为值得支持。
