title: Golgi inheritance in the primitive red alga, Cyanidioschyzon merolae.
abstract: The Golgi body has important roles in modifying, sorting, and transport of proteins and lipids. Eukaryotic cells have evolved in various ways to inherit the Golgi body from mother to daughter cells, which allows the cells to function properly immediately after mitosis. Here we used Cyanidioschyzon merolae, one of the most suitable systems for studies of organelle dynamics, to investigate the inheritance of the Golgi. Two proteins, Sed5 and Got1, were used as Golgi markers. Using immunofluorescence microscopy, we demonstrated that C. merolae contains one to two Golgi bodies per cell. The Golgi body was localized to the perinuclear region during the G1 and S phases and next to the spindle poles in a microtubule-dependent manner during M phase. It was inherited together with spindle poles upon cytokinesis. These observations suggested that Golgi inheritance is dependent on microtubules in C. merolae.
