Effects of caffeine pre- and posttreatment on the frequencies of sister chromatid exchanges and exchange-aberrations induced by quinacrine mustard and UV-light in Vicia faba L


, : Effects of caffeine pre- and posttreatment on the frequencies of sister chromatid exchanges and exchange-aberrations induced by quinacrine mustard and UV-light in Vicia faba L. Cytologia 54(2): 359-363

Lateral roots of V. faba were grown for one cell cycle in the presence of 5'-bromodeoxyuridine followed by another cell cycle in the presence of thymidine. Between these treatments root tips were exposed to either quinacrine mustard or UV-light, both known to induce structural chromosome aberrations of the exchange type and sister chromatid exchanges (SCE).
