摘要
植物叶绿素暗合成能力与非光依赖型原叶绿素酸酯还原酶(DPOR)有关,光合生物进化过程中从细菌到裸子植物均保留了这个古老的酶,完全黑暗条件下可以合成叶绿素。被子植物则由于丢失了这个酶,失去了叶绿素暗合成能力。本文综合国内外有关非光依赖叶绿素合成的研究成果,从叶绿素合成途径过程的关键反应、叶片中质体结构及光系统发育等方面,对黑暗条件下植物叶绿素合成进行综述,并从植物进化角度对叶绿素暗合成及其影响因素做了总结,为研究植物暗形态建成以及暗-光转变过程中光合器官建成提供基础。
The light-independent protochlorophyllide reductase(DPOR) was related to the ability of plants to synthesize chlorophyll in complete darkness. As an ancient enzyme, DPOR has been reserved in photosynthetic organisms from bacteria to gymnosperm, while missed in angiosperm. Therefore, angiosperm could not synthesize chlorophyll in darkness. In this review, we summarize recent advances concerning chlorophyll biosynthesis pathway. We also discuss the dark chlorophyll synthesis in the aspect of evolution and influencing factors, providing a collection of references for further researches in plants skotomorphogenesis and photosynthetic apparatus development during dark-light transition process.
