Physicochemical modeling of the phytochrome-mediated photothermal sensing

Abstract Light and temperature cues share many common signaling events towards plant photothermal morphogenesis. Particularly, the red (R)/far-red (FR)-absorbing phytochrome photoreceptors also function as temperature sensors, suggesting that light and temperature responses are intimately associated...
