2025 biology talkshow:中研究新發表~合成二碳植物!McG循環

一項關於植物光合作用效率的突破性研究概述，該研究由中央研究院的團隊執行。研究人員透過合成生物學設計了一種名為「McG循環」（Malyl-CoA-glycerate cycle）的人工固碳系統，並將其導入阿拉伯芥植物中，使其與原有的卡爾文循環協同作用，創建出「雙固碳系統」。這個新系統顯著克服自然光合作用中碳損失的兩大問題，即光呼吸作用和油脂合成時的二氧化碳釋放。實驗結果顯示，經改造的植物其固碳效率提升了約50%，生長量增加兩到三倍，並且油脂合成量大幅增加。研究團隊指出，這項成果為提升農作物產量、減緩碳排放以及生產再生能源開闢了新方向，但強調實際應用前仍需解決如性狀穩定性等多項挑戰。 Powered by Firstory Hosting
