光合成の誕生は生命の進化に留まらず, 地球環境の形成にも重要な役割を担ってきた. また, 地球環境も光合成の進化に決定的な影響を与えてきた. 地球環境と光合成は共進化してきたが, 両者の間には矛盾も存在する. ここでは特に, 二酸化炭素と植物の応答に焦点をあて, 地球環境と光合成の関連について議論する.
The first photosynthetic organism appeared in this planet is photosynthetic bacteria, which did not evolve oxygen in the process of photosynthesis. About 2.5 billion years ago, first oxygenic phototroph, cyanobacteria, appeared on the earth and evolved molecular oxygen. This event was the start of the changes in global environment. The concentration of CO2 in the atmosphere has been decreased and photosynthetic organisms developed their photosynthetic machinery according to environmental changes. We discuss the evolution of photosynthesis in relation to the environmental changes.
