摘　　要：光合作用是植物生理学研究的重要领域.莱茵衣藻是用于研究光合作用遗传的重要模式植物.本文以叶绿素b的合成途径为线索,阐述了以莱茵衣藻为工具,对合成途径各调控酶及其编码基因的研究成果.重点讨论对比了有关叶绿素b合成的不同观点,对于CAO基因与CBN1基因这两个叶绿素b的主控基因进行了分析,提出要弄清叶绿素b的合成途径,首先要弄清两基因是否为同源基因.用“点滴试法”与彩色数字成像法对莱茵衣藻色素调节基因突变株进行检测和分析,通过筛选调控基因相关突变株,就可为莱茵衣藻中叶绿素b生物合成相关基因调控机制的研究尊定基础.Photosynthesis is an important field in plant physiology. Chlamydomonas reinhardtii is an important model alga to investigate genes of photosynthesis. The article describes various approaches to study on genetics of chlorophyll b biosynthesis in Chlamydomonas reinhardtii. Different views of chlorophyll b synthesis are discussed. After analyzing CAO gene and CBN1 gene that are both considered critical genes for chlorophyll b biosynthesis, we considered that the decision should be made whether two genes are homologous or not. Identifying and analyzing the mutants impaired in pigment synthesis could be accomplished by spot-test and colorful figure imaging. Screening of such mutants will pave the road for further studies on genetic regulation of chlorophyll b biosynthesis
