项目摘要

This action funds an NSF Postdoctoral Research Fellowship in Biology for FY 2021, 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. A principal difficulty in biology is understanding how complex traits in an organism diversify, since complex traits can serve numerous functions and are controlled by multiple genes. Plants and insects are the two most diverse groups on earth and are important to multiple ecosystems. The ability to detect floral scents by insects affects many plant-insect interactions. This project will investigate the genetic evolution of insect smell (olfaction). This research will combine gene-level data with the knowledge of a Panamanian insect communities and plant-insect associations. Integrating these biological scales can help our understanding of how and why environmental and ecological variation generates and maintains variation in complex traits. The Fellow will develop a science communication workshop to foster a collaborative mentoring environment between college students and scientists.Insect chemosensory gene families on the antennae participate in the olfactory recognition of floral scents. This project will unravel ecological factors contributing to the genomic evolution of floral scent detection in the highly co-evolved symbiosis between figs (genus Ficus) and fig wasps (superfamily Chalcidoidea). By addressing three questions: (1) Does pollinating and non-pollinating fig wasp attraction to the same fig host result in convergent evolutionary patterns at the genomic level? (2) Is greater host breath and attraction to a larger diversity of floral scents associated with greater chemosensory gene family variation? (3) Is a larger effective population size also associated with greater chemosensory gene family variation? To answer the aforementioned questions, the Fellow will use next-generation sequencing to construct de novo genomic references. Furthermore, the fellow will incorporate comparative genomics with fig wasp community composition, estimates of effective population size, and plant-host association. This project will provide opportunities for the Fellow to gain new skills in genomics, de novo genome assembly, and wet lab techniques. The broader impacts of this project include the development of a grant writing and science communication workshops with the goals to (1) disseminate tips and information on grant writing, (2) foster a mentoring environment in which participants can share their research, and (3) help establish professional connections and mentoring relationships among participants.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2021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。 生物学中的一个主要困难是理解生物体中的复杂性状是如何多样化的,因为复杂性状可以发挥多种功能,并由多个基因控制。植物和昆虫是地球上最多样化的两个群体,对多种生态系统都很重要。昆虫感知花的气味的能力影响着许多植物与昆虫的相互作用。本计画将探讨昆虫嗅觉的遗传演化。这项研究将联合收割机基因水平的数据与巴拿马昆虫群落和植物昆虫协会的知识相结合。整合这些生物尺度可以帮助我们理解环境和生态变化如何以及为什么会产生和维持复杂性状的变化。该研究员将开发一个科学交流工作坊,以促进大学生和科学家之间的合作指导环境。昆虫触角上的化学感受基因家族参与对花香的嗅觉识别。该项目将揭示生态因素对无花果(榕树属)和无花果小蜂(小蜂总科)之间高度共进化共生的花香检测基因组进化的贡献。通过回答三个问题:(1)传粉和非传粉榕小蜂对同一榕属寄主的吸引是否导致了基因组水平上的趋同进化模式?(2)更大的主机呼吸和吸引力,更大的多样性的花香与更大的化学感受基因家族的变异?(3)更大的有效种群规模是否也与更大的化学感受基因家族变异相关?为了回答上述问题,研究员将使用下一代测序技术构建从头基因组参考。此外,该研究员将把比较基因组学与榕小蜂群落组成,有效人口规模的估计,和植物宿主协会。该项目将为研究员提供获得基因组学,从头基因组组装和湿实验室技术的新技能的机会。该项目更广泛的影响包括开发一个赠款写作和科学交流研讨会,其目标是(1)传播有关赠款写作的提示和信息,(2)营造一个参与者可以分享他们的研究的指导环境,以及(3)帮助参与者建立专业联系和指导关系。该奖项反映了NSF的法定使命,并被认为值得支持通过使用基金会的知识价值和更广泛的影响审查标准进行评估。
