NSF Minority Postdoctoral Research Fellowship for FY2008

这一行动为NSF 2008财年少数民族博士后研究奖学金提供了资金。该奖学金支持在东道主实验室为该研究员制定的研究和培训计划，该研究员还提出了扩大生物学参与度的计划。Ludmila Aristilde研究金的研究和培训计划的标题是“调查海洋浮游植物的细胞调节”。这项研究的主办机构是普林斯顿大学，赞助科学家是François M.M.Morel.博士。海洋中的浮游植物通过产生和分泌许多不同的富碳和含硫化合物，在全球碳和硫循环中发挥重要作用，这些化合物既影响海洋的化学成分，也影响微生物和藻类食物网的动态。这项研究以埃米利纳·赫克斯勒伊作为模式生物，试图了解这些含硫化合物之一二甲基磺酸丙酸酯是如何在细胞内以及在哪里合成的，以及这种合成与浮游生物中的光合作用反应的关系。培训的目标是学习微生物学和生化技术的结合，以在分子一级解决具有全球重要性的问题，并在环境健康和环境生物学的界面上工作。随着大气中二氧化碳水平的持续上升和海洋表面温度的持续上升，浮游生物物种可能会改变它们的新陈代谢，包括它们的光合作用速率。这项研究有望产生更广泛的影响，有助于评估未来气候变化对地球生态系统的影响。

This action funds an NSF Minority Postdoctoral Research Fellowship for FY 2008. The fellowship supports a research and training plan in a host laboratory for the Fellow who also presents a plan to broaden participation in biology. The title of the research and training plan for this fellowship to Ludmilla Aristilde is "Investigating Cellular Regulation in Marine Phytoplankton" The host institution for this research is Princeton University and the sponsoring scientist is Dr. François M. M. Morel.Phytoplankton in the ocean play a major role in global carbon and sulfur cycles by creating and secreting many different carbon-rich and sulfur-containing compounds, which affect both the chemistry of the ocean and the dynamics of microbial and algal foodwebs. Using Emilina huxleyi as a model organism, this research seeks to understand how and where in the cell one of these sulfur-containing compounds, dimethylsulfoniopropionate, is synthesized and the relationship of this synthesis to photosynthetic reactions in the plankton. The training objectives are to learn a combination of microbiological and biochemical techniques to address a problem of global importance at the molecular level and to work at the interface of environmental health and environmental biology. As atmospheric levels of carbon dioxide continue to increase and the temperature of the ocean surface also continues to rise, plankton species may be seen to alter their metabolism including their rates of photosynthesis. This research promises to have broader impacts by contributing to the assessment of the impacts of future climate change on the earth's ecosystems.
