Effect of Isopropyl N-Phenilcarbamate on Euglena

Sažetak
The effects of the herbicide isopropyl N—N phenylcarbamate (IPC) on wild type Euglena and three bleached mutants (yellow, pale yellow and white) have been studied.
IPC is a slowly acting, rather weak, herbicide which inhibits cell division in all Euglena strains studied. This inhibition depends on the nutritional history of cells and the adaptability of the strain to the ethanol used to dissolve IPC.
Wild type Euglena is most sensitive to IPC, especially if cultured in the light, although the lethal dose has been found to be the same for all strains studied (10-3 M).
Most metabolic changes, such as appearance of monstrous forms, and inhibition of chlorophyll and paramylum synthesis, are seen at an intermediate dose of about 5 X 10-4 M.
IPC does not cause bleaching i. e. irreversible permanent loss of chloroplasts.
This study confirms that IPC does not only act on autotrophic plant cells, but on cells of heterotrophic organisms as well.
