Outline of Final Research Achievements

Function of Auxin transcriptional regulators were analyzed in the root phototropic response, which is induced independently of asymmetric auxin distribution. Auxin trascriptional facotr ARF7, transcriptional regulator IAA19 and auxin receptor TIR1 were involved in the phototropic response of roots. However, our results suggested that their function are not controlled by the phototropin signaling pathways.
