概要

• 論文の詳細を見る

• A digital image processing technique was developed for the simultaneous detection of changes in organelle movements in different regions of a cell from the protonemata of the fern, Adiantum. The speed of particle movements at a chosen position in a series of dynamic images that had been recorded by a time-lapse video system was determined in terms of standard error of brightness changes with a gray scale level. Using this new method and microscopy we could distinguish 3 different regions during mitosis in terms of organelle movement patterns. Organelles located outside of the nucleus were in movement until the nucleolus disappeared at prophase, whereas organelles in the boundary region between the nucleus and cytoplasm became active after prophase. The organelles located outside the nucleus again began to move rapidly after chromosome separation. The nuclear pole region showed movement throughout mitosis.
