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

我们迄今已报道的证据表明，差异侧翼增长，导致phototoropic曲率是受蓝光诱导的生长抑制剂（Bruinsma-Hasegawa理论）。在这项研究中，我们报告，蓝光促进了H2 O2的积累和随后的木质化在照明侧和萝卜素或丁布应用的萝卜幼苗的一半。或玉米，分别因此，这些特定的蓝光诱导的生长抑制剂调节植物的向光性。

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.
