Abstract

Plants integrate signals from the environment and use these to modify the timing of development according to seasonal cues. Seed germination is a key example of this phenomenon and in Arabidopsis is promoted by the synergistic interaction of light and low temperatures in dormant seeds. This signaling pathway is known to converge on the regulation of the gibberellin (GA) biosynthetic genes GA3 oxidase (GA3ox), whose expression is transcriptionally induced by light and cold in imbibed seeds. However, the molecular basis of this response has until now been unknown.
