Plants are growing to or away from light direction to adapt to their light environments. The responses, so-called phototropism, have been well-studied for a long time. Auxin, one of plant hormones, is known to stimulate plant growth and thought to be involved in phototropism by changing its endogenous distribution in responses to light irradiation. The present study analyzed phototropic responses of Arabidopsis seedling roots, and demonstrated existence of molecular mechanisms underlying phototropic responses independent of auxin asymmetrical lateral distribution. Our investigations strongly suggested that light stimulation directly controls regulatory components involved in auxin-mediated responses, such as auxin receptors and/or auxin responsive transcription factors. The present results contribute to establishment of a new model responsible for phototropic responses.
