叶绿素是光合生物中最丰富的四吡咯分子，对光合作用至关重要。经过多年的深入研究，大多数编码该途径的酶的基因已经被鉴定，最近已经阐明了潜在的分子机制。这些研究表明，叶绿素代谢的调节包括所有水平的控制，以允许响应外部和内源因素的平衡代谢流，并确保适应植物发育期间叶绿素的不同需求。此外，从各种生物中鉴定生物合成基因并对所鉴定基因的功能进行遗传分析，使我们能够预测叶绿素代谢的进化情况。本文就近年来叶绿素代谢的研究进展作一综述。
Chlorophylls are the most abundant tetrapyrrole molecules essential for photosynthesis in photosynthetic organisms. After many years of intensive research, most of the genes encoding the enzymes for the pathway have been identified, and recently the underlying molecular mechanisms have been elucidated. These studies revealed that the regulation of chlorophyll metabolism includes all levels of control to allow a balanced metabolic flow in response to external and endogenous factors and to ensure adaptation to varying needs of chlorophyll during plant development. Furthermore, identification of biosynthetic genes from various organisms and genetic analysis of functions of identified genes enables us to predict the evolutionary scenario of chlorophyll metabolism. In this review, based on recent findings, we discuss the regulation and evolution of chlorophyll metabolism.
