项目摘要

Bees are the single most important pollinators of flowering plants worldwide. Over 85% of the 325,000 flowering plant species on earth depend on animals for pollination, and the vast majority of pollination is carried out by bees. Annually, bees are estimated to contribute $15 billion to US crop production and $170 billion to global crop production. High-value bee-pollinated crops include apple and other early spring tree fruits, strawberries, blueberries, cherries, cranberries, squash and pumpkins, tomatoes, almonds, and many others. The economic viability of US agricultural production is dependent on stable and healthy wild and domesticated bee populations. However, bee populations are threatened by a variety of factors, including habitat loss, pathogen spillover, invasive plants and animals, and pesticide use, which can disrupt the normal microbial symbionts essential for bee larval development (the "brood cell" microbiome). This research project focuses on understanding what role microbes play in the larval nutrition in a wide variety of bee species. Previous research has documented a diverse community of bacteria and yeasts in the pollen and nectar diet of bees. As larvae consume these pollen/nectar provisions they are ingesting microbes, and our preliminary results indicate that these microbes form an essential component of the larval diet. This project has the potential to significantly modify how we view the 120 million-year-old partnership between bees and flowering plants, and will provide essential information for developing long-term bee conservation efforts. Project outreach efforts include educational activities on solitary bees for K-12 students and interactive demonstrations of bee-microbe-flower interactions for broad audiences. The project will use cutting-edge methods to (1) document the microbial diversity in flowers and pollen provisions, (2) determine the nutritional role of microbes in larval development and health, and (3) understand how alterations in microbial community impact larval development. To document microbial diversity in both host-plant flowers and pollen provisions, the research team will use amplicon sequencing and microbial metagenomics. These methods will document the microbial species present in pollen provisions as well as the metabolic activities these microbes perform during pollen maturation. Screening the pollen and nectar of host-plant species will provide key insights into the source of the brood cell microbiome. To determine the nutritional role of the microbial community the research team will use two methods from trophic ecology: compound specific isotope analysis and neutral lipid fatty acid analysis. These analyses will permit the research team to track the origin (floral or microbial) of amino acids and fatty acids in the larval diet of 15 focal bee species. Finally, through manipulative laboratory experiments the research team will determine how modifications of the microbial communities impact larval development. Combining the results of these studies will provide a comprehensive understanding of how bees and flowering plants interact via their shared microbial partners. This project is jointly funded by the Systematics and Biodiversity Sciences Cluster (Division of Environmental Biology) and the Symbiosis, Defense and Self-recognition Program (Division of Integrative Organismal Systems).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.
蜜蜂是全世界开花植物最重要的传粉者。地球上325,000种开花植物中有超过85%依赖动物授粉,绝大多数授粉是由蜜蜂进行的。据估计,蜜蜂每年为美国作物生产贡献150亿美元,为全球作物生产贡献1700亿美元。高价值的蜜蜂授粉作物包括苹果和其他早春树果,草莓,蓝莓,樱桃,蔓越莓,南瓜和南瓜,西红柿,杏仁和许多其他作物。美国农业生产的经济可行性取决于稳定和健康的野生和驯养蜜蜂种群。然而,蜜蜂种群受到各种因素的威胁,包括栖息地丧失、病原体溢出、入侵植物和动物以及杀虫剂的使用,这些因素可能会破坏蜜蜂幼虫发育所必需的正常微生物共生体(“育雏细胞”微生物组)。该研究项目的重点是了解微生物在各种蜜蜂物种的幼虫营养中发挥的作用。以前的研究已经记录了蜜蜂花粉和花蜜饮食中的细菌和酵母菌的多样性。由于幼虫消耗这些花粉/花蜜的规定,他们是ingredient微生物,我们的初步结果表明,这些微生物形成幼虫饮食的重要组成部分。该项目有可能显著改变我们对蜜蜂和开花植物之间1.2亿年历史的伙伴关系的看法,并将为制定长期的蜜蜂保护工作提供重要信息。项目外展工作包括为K-12学生举办关于孤独蜜蜂的教育活动,并为广大观众展示蜜蜂-微生物-花朵相互作用的互动示范。该项目将使用尖端的方法来(1)记录花卉和花粉供应中的微生物多样性,(2)确定微生物在幼虫发育和健康中的营养作用,以及(3)了解微生物群落的变化如何影响幼虫发育。为了记录宿主植物花朵和花粉中的微生物多样性,研究小组将使用扩增子测序和微生物宏基因组学。这些方法将记录花粉中存在的微生物种类以及这些微生物在花粉成熟过程中的代谢活动。筛选寄主植物物种的花粉和花蜜将提供对育雏细胞微生物组来源的关键见解。为了确定微生物群落的营养作用,研究小组将使用营养生态学的两种方法:化合物特定同位素分析和中性脂质脂肪酸分析。这些分析将使研究小组能够追踪15种重点蜜蜂幼虫饮食中氨基酸和脂肪酸的来源(植物或微生物)。最后,通过操纵实验室实验,研究小组将确定微生物群落的修改如何影响幼虫发育。结合这些研究的结果将提供一个全面的了解蜜蜂和开花植物如何通过他们的共同微生物合作伙伴相互作用。该项目由系统学和生物多样性科学组(环境生物学部)和共生、防御和自我认可计划(综合有机体系统部)共同资助。该奖项反映了NSF的法定使命,并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,被认为值得支持。
