Abstract
TRANSCRIPTIONAL events are arrested in developing plant seeds when maturation is completed. The RNA synthesis may be resumed when suitable changes in the environment make it possible for the seed to germinate. It is not known, however, how early and in what order the synthesis of cellular RNA species is activated in response to the stimulus to germinate. Our previous observations1,2 indicate that RNA synthesis is triggered almost immediately before the activation of protein synthesis in vivo but other reports3–5 suggest that RNA synthesis remains repressed for many hours after germination starts. Further attempts to establish the time course of RNA synthesis in germinating wheat embryos were therefore undertaken.
