Figure 7From: The role of the Arabidopsis FUSCA3transcription factor during inhibition of seed germination at high temperatureProposed model of thermoinhibition of seed germination. During seed germination at supraoptimal temperature, induction of ABA and repression of GA syntheses and signaling delays germination. FUS3 acts in a short developmental window to prevent seedling growth, by positively regulating ABA while negatively regulating GA biosyntheses. ABA increases FUS3 stability by positive feedback regulation.Back to article page
