The Role of Silicon and Light in Regulating Diatom Cell Cycles

硅藻是微小的单细胞植物，负责海洋中大部分的生物生产力。它们对硅的绝对需求使它们在浮游植物中独一无二，本研究将讨论光和硅在调节这些植物的细胞分裂(或生长)中的相互作用。奇泽姆博士和一名博士后研究员将与伍兹霍尔海洋研究所的奥尔森博士合作，研究几个问题，这些问题涉及硅藻细胞分裂周期中受光和二氧化硅可获得性控制的阻塞点的确切性质和数量。应对这些限制的具体策略将在海洋生物学的高度集成细胞生物学方法中使用细胞细胞术进行研究。

Diatoms are microscopic, single celled plants that are responsible for much of the biological productivity in the ocean.Their absolute requirement for silica makes them unique among the phytoplankton and the interaction of light and silica in regulating the cell division (or growth) of these plants will be addressed in this research. Dr. Chisholm and a post doctoral researcher will collaborate with Dr. Olson from Woods Hole Oceanographic Institute to examine several questions regarding the exact nature and number of block points in the diatom cell division cycle that are controlled by light and silica availability. The specific strategies for dealing with these limitations will be studied using cell cytometry in a highly integrated cell biological approach to marine biology.
