NSF Minority Postdoctoral Research Fellowship for FY2008

这项行动为2008财政年度的NSF少数民族博士后研究奖学金提供资金。该研究金支持研究员在东道实验室的研究和培训计划，研究员还提出了扩大生物学参与的计划。Ludmilla Aristilde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.莫雷尔。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着重要作用，这些化合物影响海洋的化学成分以及微生物和藻类食物网的动态。本研究以Emilina huxleyi为模式生物，试图了解这些含硫化合物之一，二甲基磺基丙酸酯在细胞中是如何合成的，以及这种合成与浮游生物光合反应的关系。 培训目标是学习微生物和生物化学技术的结合，以解决在分子一级具有全球重要性的问题，并在环境卫生和环境生物学的接口工作。随着大气中二氧化碳含量的持续增加，海洋表面的温度也持续上升，浮游生物物种可能会改变它们的新陈代谢，包括光合作用的速率。 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.
