摘  要:光合作用被称为“地球上最重要的化学反应”,其二氧化碳同化是由还原辅酶II(NADPH)和腺三磷(ATP)来推动的。ATP主要来源于非循环光合磷酸化和循环光合磷酸化,但以往研究集中在前者。21世纪以来,随着测定技术的发展和多条与循环光合磷酸化有关的电子传递途径的发现,循环光合磷酸化的重要性和功能引起了极大地关注。该文作者结合自己实验室的相关的研究,围绕循环光合磷酸化的发现和重要性、同化力两个组分的比例与促进光合磷酸化提高光合作用的途径进行探讨,为进一步深入研究提供参考。
关键词:循环光合磷酸化;光合作用

Abstract: Photosynthesis is the most important chemical reaction on the earth, its assimilation of carbon dioxide is pushed by dihydrocoenzyme II (NADPH) and adenine triphosphate (ATP). ATP is mainly derived from non-cyclic photophosphorylation and cyclic photophosphorylation,the former were widely studied in the past. Since 21 century, the importance and function of cyclic photophosphorylation are immensely focused with the development of determination technology and discoveries of electron transport pathways related with cyclic photophosphorylation. In this paper, the authors discussed the discoveries and importance of cyclic photophosphorylation, the ratio of two assimilatory power components and the pathways of promoting photophosphorylation to improve photosynthesis on the basis of interrelated researches in their own laboratory, which are provided references for further intensive study in the future.
Key words: cyclic photophosphorylation; photosynthesis
