Abstract
A DNA base analogue, 5-bromodeoxyuridine (BUdR), promoted flowering of Arabidopsis thaliana in short and long photoperiods and even in total darkness. The promotive effect of BUdR was nullified by thymidine which had a weak inhibitory effect by itself. Another DNA base analogue, 5-fluorodeoxyuridine (FUdR), inhibited the flowering at a low concentration (10−8 M), but markedly enhanced the promotive effect of BUdR if they were present together in the culture medium. In the flower-promoting medium containing both BUdR and FUdR, the number of acid phosphatase isozymes decreased temporarily, followed by an increase to the control level with a prolonged culture period. The number of peroxidase isozymes was greater in plants grown in the medium with BUdR or BUdR $ FUdR than in those without them.
