关于长寿命mRNA的研究──（Ⅵ）CPA对绿豆种子中预存mRNA转译的调控作用及其诱导胚轴下端膨大的显微结构观察

Studies on Long-Lived mRNA── (Ⅵ)Observation to the Microscopic Structure of Hypocotylar Swelling Induccd by CPA which Regulates Translation of Long-Lived mRNA in Vigna Radiata

应用转录抑制剂放线菌素Ｄ和转译抑制剂环己亚胺为工具进行的实验表明，绿豆种子中预存ｍＲＮＡ的转译可以受到ＣＰＡ的调控，表现为诱导过氧化物酶同工酶出现新的酶带和幼苗胚轴下端产生膨大并进而形成愈伤组织，对ＣＰＡ诱导的上述形态效应进行了显微观察．

By the experiments with actinomycin D and cycloheximide, it was discoveredfor the first time that long-lived mRNA exit in seeds of Gymnosperm, P. masso-niana. Translation of the long-lived mRNA could be regulated by p-chloropheno-xyacetic acid (CPA) which enhanced some bands in isoenzyme patterns of peroxideand cytochrome oxidase.
