- Abstract
The highly complex and symmetric endomembrane network of the chlamydomonad alga, <em>Gloeomonas kupferri</em>, can be disrupted by the herbicide, isopropyl N-phenyl caramate (IPC). Upon incubation with IPC for between 30 min and 1h, curling of the dictyosomes, proliferation of small vesicles from the trans face and swelling of the peripheral vacuolar complex takes place. Longer treatments result in degeneration of dictyosome cisternae into vesicular masses and the formation of supervacuolar complexes. Enzyme cytochemistry revealed that endomembrane 'marker enzymes are altered/inhibited by IPC. A second but striking IPC-induced effect is the production of branched, fibrillar inclusions in the cell nucleus. A discussions of IPC-induced affects on ion regulation and microtubule/MTOC distribution in the cell is presented.
