在两个海洋中心硅藻的叶绿体的运动进行了研究：在Ditylum brightwellii的叶绿体向外和向内移动的光-暗周期，和在Odontella regia的叶绿体是固定在细胞质中。通过免疫荧光显微镜和电子显微镜确定了叶绿体和细胞骨架之间的物理关系，并使用细胞骨架抑制剂研究了叶绿体运动中细胞骨架的可能参与。结果表明，在叶绿体周围有微管和微丝; brightwellii和参与他们的运动。微管和微丝与O. regia。
Movements of the chloroplasts were studied in two marine centric diatoms: in Ditylum brightwellii the chloroplasts move outward and inward during the light-dark cycle, and in Odontella regia the chloroplasts are stationary in the cytoplasm. Physical relationships between chloroplasts and cytoskeleton were determined by immunofluorescence microscopy and electron microscopy, and the possible involvement of the cytoskeleton in the movements of chloroplasts was investigated using cytoskeleton-inhibitors. The results show that microtubules and microfilaments surround the chloroplasts of D. brightwellii and are involved in their movements. Neither microtubules nor microfilaments have a close relationship with the chloroplasts of O. regia.
