项目摘要

The evolution of oxygenic photosynthesis changed the trajectory of life on Earth. By about 2.4 billion years ago, photosynthesis began to cause accumulation of oxygen in Earth’s atmosphere. This oxygen eventually allowed multicellular animals to evolve. However, scientists do not know when or how oxygenic photosynthesis evolved. Understanding its origin requires integrating data and ideas from biochemistry, microbiology, evolutionary biology, and Earth history. This project will bring together individual scientists with the breadth of knowledge and diversity of skills to identify and address the key questions for understanding oxygenic photosynthesis. Specifically, researchers will design a cross-disciplinary Biology Integration Institute on The Evolution of Oxygenic Photosynthesis. The team will include university students and early career scientists who will learn cross-disciplinary techniques through participation in project-related activities and as part of a graduate level course that integrates appropriate sciences. Public outreach and education projects will show others how scientists work together on complicated problems. The researchers are committed to diversity, inclusivity, and academic excellence, and they will apply best practices for broadening participation and integrating educational components into the project. The researchers will establish a cross-disciplinary collaboration at UC Davis to investigate the evolution of oxygenic photosynthesis. Through a series of workshops, they will: 1) assess current knowledge and hypotheses; 2) articulate outstanding questions that transcend subdisciplines and can be productively addressed by an interdisciplinary team; 3) identify additional key collaborators to address research questions; 4) build an interdisciplinary and interinstitutional research team to answer the target questions; and 5) host a writing workshop for all collaborators to construct an Implementation proposal with active participation from the full Implementation team. This project advances the mission of the Biology Integration Institute and NSF by linking researchers across biological and geological disciplines.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.

含氧光合作用的进化改变了地球上生命的轨迹。大约24亿年前，光合作用开始导致地球大气中氧气的积累，这种氧气最终使多细胞动物得以进化。然而，科学家们并不知道含氧的时间和方式。了解光合作用的起源需要整合来自生物化学、微生物学、进化生物学和地球历史的数据和想法，该项目将汇集知识广度和技能多样性的科学家来识别和解决光合作用的问题。研究人员将设计一个关于产氧光合作用进化的跨学科生物整合研究所，该团队将专门包括大学生和早期职业科学家，他们将通过参与项目相关活动来学习跨学科技术。作为整合适当科学的研究生课程的一部分，研究人员将向其他人展示科学家如何致力于多样性、包容性和学术卓越，并且他们将应用最佳实践来扩大研究范围。参与研究人员将在加州大学戴维斯分校建立跨学科合作，通过一系列研讨会来研究氧气光合作用的演变，他们将：1）评估当前的知识和假设；2）阐明突出的问题；超越子学科，可以由跨学科团队有效地解决；3）确定其他关键合作者来解决研究问题；4）建立一个跨学科和跨机构的研究团队来回答目标问题；5）为所有人举办写作研讨会；该项目通过将生物和地质学科的研究人员联系起来，推进了生物整合研究所和 NSF 的使命。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。
