摘　　要：叶绿素生物合成由L-谷氨酰-tRNA到叶绿素a和叶绿素b共有15个步骤,涉及15种酶催化反应,其中任何一种酶基因突变或通过抑制剂抑制其活性均有可能导致叶绿素含量变化,从而影响光合效率甚至导致植株死亡。高等植物体内的叶绿素合成是一个复杂的过程,它除了受如光照、稀土元素等外部环境条件调控以外,其内在基因调控也十分重要。本综述将高等植物叶绿素生物合成途经划分为三个阶段,以此概述其最新研究进展。Chlorophyll biosynthesis consists of 15 steps fromL-glutamyl-tRNA to chlorophyll a and chlorophyll b, involving 15 enzyme-catalyzed reactions. Anyone of the enzyme gene mutations or inhibition of its activity by inhibitors may lead to changes in chlorophyll content, which affects photosynthesis efficiency and even lead to plant death. Chlorophyll synthesis in higher plants is a complex process. In addition to being regulated by external environmental conditions such as light and rare earth elements, its intrinsic gene regulation is also important. In this paper, the chlorophyll biosynthesis pathway of higher plants is divided into three stages to summarize its latest research progress.
