Abstract

The formation of protochlorophyllide and protochlorophyllide phytyl ester was investigated during etioplast biogenesis in order to study the biosynthetic relation of these two compounds. Protochlorophyllide accumulates slowly during the first 2 days of germination, its rate of formation increases sharply during the 3rd day, and then it decreases. Protochlorophyllide phytyl ester starts accumulating a day later; its formation coincides with the initiation of xanthophyll biosynthesis. Kinetic analysis of specific radioactivities after (14)C labeling of the protochlorophyll pools does not support the currently accepted conversion of protochlorophyllide into protochlorophyllide phytyl ester, but suggests that both compounds originate simultaneously from a common precursor pool.

摘要

为了研究这两种化合物的生物合成关系,在黄化质体生物发生过程中对原叶绿素酸酯和原叶绿素酸酯植醇酯的形成进行了研究。在萌发的前两天,原叶绿素酸酯积累缓慢,在第三天其形成速率急剧增加,然后下降。原叶绿素酸酯植醇酯一天后开始积累;其形成与叶黄素生物合成的起始相吻合。在用(14)C标记原叶绿素池后对特定放射性的动力学分析不支持目前所接受的原叶绿素酸酯向原叶绿素酸酯植醇酯的转化,但表明这两种化合物同时起源于一个共同的前体池。
