The blue-light receptor CRY1 serves as a switch to balance photosynthesis and plant defense
Previously, photoreceptors were regarded as a switch for growth control. Hao et al. found that CRY1 acts as dual-control switch to regulate the growth-defense trade-off. LURP1 re-localizes to the plasma membrane upon N-terminal palmitoylation in a calcium- and blue-light-dependent manner after flg22 elicitation to activate immune receptors and promote immunity.
