Study on Mechanism of Key Substances involved in Plant Movement, Phototropism

到目前为止，我们已经报道的证据表明，导致光折变曲率的差异侧翼生长受到蓝光诱导的生长抑制物(Bruinsma-Hasegawa理论)的调节。在本研究中，我们报道了蓝光促进H_2O_2的积累和随后的木质化在光照侧和萝卜或DIMBOA分别应用于萝卜或玉米幼苗的一半。因此，、这些特定的蓝光诱导生长抑制物调节植物的向光性。

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.
