• It is concluded that the ca2 + influx from the apoplast through the ca2 + channel in the pm plays pivotal role in the hypocotyl curvature toward low - fluence bl . and we can give a further hypothesis that phototropin may act as the upstream regulator of calcium channel in the pm , from which the ca2 + influx and form the ca2 + singling as the second messenger in the cytoplasma
  综合以上的研究结果，本论文探讨了c扩+参与下胚轴向光弯曲反应中的可能作用机制，提出了质膜钙离子通道在photl介导的蓝光诱导下胚轴向光反应中可能的作用模式。
