The interactive effects between far-red light and temperature on lettuce growth and morphology diminish at high light intensity.

ABSTRACT: Phytochromes (PHYs) play a dual role in sensing light spectral quality and temperature. PHYs can interconvert between the active P_fr form and inactive P_r form upon absorption of red (R) and far-red (FR) light (Photoconversion). In addition, active P_fr can be converted to inactive P_r in a temperature-dependent manner (Thermal Reversion). Recent studies have shown that FR light and temperature can interactively affect plant growth and morphology through co-regulating phytochrome activities. These studies were primarily conducted under relatively low light intensities. As light intensity increases, the impact of thermal reversion on phytochrome dynamics decreases. However, the light intensity dependency of the interactive effects between FR light an
