The Role of Silicon and Light in Regulating Diatom Cell Cycles

硅藻是微小的单细胞植物， 负责大部分的生物生产力， 它们对二氧化硅的绝对需求使它们独一无二 以及光和硅的相互作用 在调节这些植物的细胞分裂（或生长）方面， 在这项研究中得到解决。 奇泽姆博士和一名博士后 研究人员将与来自伍兹霍尔的奥尔森博士合作 海洋学研究所审查关于下列问题的若干问题： 硅藻细胞中阻滞点的确切性质和数量 由光和硅控制的分裂周期 空房的 应对这些的具体策略 限制将使用细胞计数法在一个高度 海洋生物学的综合细胞生物学方法。

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.
