Abstract
In Physarum polycephalum, transcription is significantly inhibited for the
whole of the ultra violet-induced, extended G2 phase. Although, there is some increase
in the rate of transcription closer to the first post-irradiation mitosis, thereafter, ovrall
synthesis continues to be low. Also, the plasmodia developed significant resistance to
actinomycin D during this period. The resistance is both in terms of mitosis and RNA
synthesis. The overall depression in transcription and the drug resistance are apparently
related phenomena.
