This project is an outgrowth of a project previously funded by OTIC to develop a method for environment micro-compartment genomics (EMCG) of DNA particles and if this method is successful for RNA, it has potential important applications not only in marine RNA virus research but also in public health and epidemiology. Current methods are not sensitive enough to detect small RNA viruses making quantification of RNA viruses in marine samples difficult. Methods for direct quantification are needed to verify the numbers in marine habitats. RNA viruses and virus-like particles in the ocean, play a major role in microbial ecology and evolution. The ability to analyses of individual RNA viruses would potentially be transformative in oceanography as well as public health and epidemiology. As a result of this Bigelow Laboratory’s Single Cell Genomics Center (SCGC) would provide this analysis as a service to the global research community. The PI’s will also mentor an undergraduate student and provide advanced courses Bioinformatics of Microbial Single Cells and Aquatic Flow Cytometry.The role of RNA viruses is even less understood than those of DNA-containing extracellular genetic elements, due to technical challenges. The PIs have previous OTIC funding to develop environment micro-compartment genomics (EMCG) of DNA particles Early results of this project suggests that a modification of the EMCG methods may enable genomic sequencing of both DNA and RNA particles, thus addressing this pressing need. The PIs request EAGER funding to develop a novel, microencapsulation-based technology for whole genome sequencing of RNA viruses from the ocean, with potential applications in other environments.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.

该项目是OTIC先前资助的一个项目的产物，该项目旨在开发一种用于DNA颗粒的环境微区室基因组学（EMCG）的方法，如果该方法成功用于RNA，则它不仅在海洋RNA病毒研究中而且在公共卫生和流行病学中具有潜在的重要应用。目前的方法不够灵敏，无法检测小RNA病毒，难以定量海洋样品中的RNA病毒。需要直接量化的方法来核实海洋生境中的数量。海洋中的RNA病毒和病毒样颗粒，在微生物生态学和进化中起着重要作用。分析单个RNA病毒的能力可能会在海洋学以及公共卫生和流行病学方面带来变革。因此，毕格罗实验室的单细胞基因组学中心（SCGC）将为全球研究界提供这种分析服务。PI还将指导一名本科生，并提供高级课程微生物单细胞生物信息学和水生流式细胞术。由于技术挑战，RNA病毒的作用甚至比含DNA的细胞外遗传元件的作用更少。PI之前获得了OTIC的资金，用于开发DNA颗粒的环境微区室基因组学（EMCG）该项目的早期结果表明，EMCG方法的修改可以实现DNA和RNA颗粒的基因组测序，从而解决这一迫切需求。PI请求EAGER资助开发一种新的、基于微生物技术的海洋RNA病毒全基因组测序技术，该技术在其他环境中具有潜在的应用。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。
