摘　　要：除了经过光系统II和光系统I的非循环电子传递以外,围绕光系统I的循环电子传递对维持高效率的光合作用也是不可缺少的,其中叶绿体还原型二(三)磷酸吡啶核苷酸[NAD(P)H]脱氢酶复合体(NDH复合体)介导的循环电子传递是目前研究的热点。随着质体末端氧化酶(PTOX)的发现,NDH参与的循环电子传递与叶绿体呼吸在补充光合作用所需能量以及抵御光氧化胁迫过程中的作用正日渐引起研究者的重视。文章根据近年的研究进展就叶绿体NDH复合体及其介导的循环电子传递与叶绿体呼吸的生理功能做了综述。Besides the non-cyclic electron transport driven by the two photosystems （PSII and PSI）, the cyclic electron transport pathways around PSI are also essential for efficient photosynthesis. As one of these pathways, the NAD（P）H dehydrogenase complex （NDH complex） mediated cyclic electron transport has been well studied. Along with the identification of the plastid terminal oxydase （PTOX）, the functions of NDH-mediated cyclic and chlororepiratory electron transport in energy supply for photosynthesis as well as in the resistance to photooxidative stress have increasingly been brought to the researchers＇ attention. In the present paper, the structural characteristics of NDH complex, the regulatory mechanism, and the physiological significance of NDH mediated cyclic electron transport and chlororespiration are reviewed.
