摘要:
黑暗中培养的萝卜黄化苗在单侧蓝光辐时下的向光性反应比较迟钝。光照预辐射可以改变黄化苗的向光性反应能力,蓝光对向光性反应能力的影响达到显着水平,而红光和远红光的作用不显着;蓝光预辐射0-2h,向光性反应能力按比例增加;1辐射2-12h,向光性反应能力的增加趋于饱和。蓝光2h诱导增强的向光性反应能力在0-8h的黑暗中可以保持1h,随后便自行逐渐减弱。本文的研究涉及到蓝光对向光性反应能力的调节,在时间上位于向光性诱导及其反应过程之前,反应能力的增强及其在黑暗中的衰减过程均能在实验条件下得到有效的控制,这些结果对进一步筛选与向光性反应能力形成有关的特异蛋白质及mRNA提供了一个可操作的实验体系。
Abstract:
The phototropic response of dark-grown seedling of radish (Paphanus sativus L.) was slow to the stimulation by unilateral ill umination with blue light.Light preirradiation could modify the phototropic capability.The resulation by blue light was significant,but that by red or farred light was not.Phototropic capability of the etiolated seedling of radish was enhanced with in 0-2h by blue-light preirradiation,but tended to be gradually satured with in 2-12h pretreatment.The enhanced phototropic capability by 2h blue light could be kept within 1h,and declined gradually under 0-8h dark condition.The regulation system of phototropic capability by pure blue light in radish would be useful for the molecular study of phototropism.
