| Research Abstract |
We have hitherto reported evidence that the differential flank growth that causes phototoropic curvature is regulated by blue light-induced growth inhibitors (Bruinsma-Hasegawa theory). In this study, we report that blue light promoted the accumulation of H2O2 and subsequent lignification in the illuminated sides and in the Raphanusanin or DIMBOA applied halves of seedlings of Raphanus sativus L. or Zea mays L., respectively. Therefore、 these specific blue light-induced growth inhibitors regulated phototropism of plants.
