【摘要】 钙调节蛋白抑制剂CPZ、TFP在10^-7—10^-6mol/l浓度范围内,明显抑制光敏色素控制的转板藻叶绿体向光转动。受抑制的丝体转移到新鲜培养液中,叶绿体恢复正常转动。外源（?）mol/l ATP可以显著减少抑制效果。实验表明,钙调节蛋白可能参与转板藻叶绿体的向光转动调节。本文讨论了钙调节蛋白在转动机制中可能的作用方式以及实验结果对光敏色素原初反应研究的意义。更多还原

【Abstract】 Calmodulin inhibitors CFZ and TEP inhibited phytochrome controlled rotation of mougeotia chloroplast within the concentration range from 10^-7 to 10^-6 tool/l. The chloroplast rotation restored when the treated Mougeotia threads were transfered to fresh culture medium. Adding extraneous 1m mol/l ATP, the inhibition effect of calmodulin inhibitors was greatly reduced. It is supposed that calmodulin probably involved in the mechanism of Mougeotia chloroplast rotation. The effecting site of calmodulin on the inhibition mechanism as well as the significance of this research to the phytochrome primary reaction was also discussed.更多还原
