Plant phototropism—directional growth in response to light—serves as a key adaptive mechanism, optimizing photosynthesis and development. Central to this process is phototropin 1 (phot1), a primary blue light photoreceptor that mediates light perception and subsequent phototropic responses. While downstream signaling pathways of phot1 have been well characterized, the upstream regulators of its kinase activity in light responses have remained elusive—until now.
