Microtubule orientation in globular leaflet cells of Chara inflata.
Chara inflata has globular leaflet cells and cylindrical internodal cells. The morphology of the leaflet cells is different from that of other Characeae. The orientation of cortical microtubules (MTs) in young leaflet and internodal cells of this species was analyzed by immunofluorescence microscopy. MTs with random orientation were observed in leaflet cells, while those relatively transverse to the cell axis were observed in cylindrical internodal cells. In cylindrical leaflet cells in Chara corallina, transverse MTs were observed. These results imply that C. inflata is a morphological mutant lacking a mechanism for orienting cortical MTs transverse in leaflet cells.
