  • 專業解析

    乙烯生物合成(ethylene biosynthesis)是植物體内産生乙烯氣體的代謝過程。乙烯作為植物激素,調控着種子萌發、果實成熟、器官脫落及逆境響應等關鍵生理活動。其合成主要通過甲硫氨酸循環(Yang Cycle)完成,具體路徑如下:

    1. 核心合成路徑

    $$ ce{Met ->[SAMS] SAM ->[ACS] ACC ->[ACO] C2H4 + CO2 + HCN} $$

    2. 調控機制

    3. 生理功能

    Ethylene Biosynthesis 指植物體内通過特定酶促反應生成乙烯(ethylene)的生物化學過程。以下是詳細解釋:

    1.核心定義

    2.合成途徑

    乙烯的生物合成主要遵循甲硫氨酸(Methionine)途徑,包含以下關鍵步驟:

    1. 甲硫氨酸 → S-腺苷甲硫氨酸(SAM):由甲硫氨酸腺苷轉移酶催化。
    2. SAM → 氨基環丙烷羧酸(ACC):通過ACC合成酶(ACS) 催化,此步驟為限速步驟。
    3. ACC → 乙烯:由ACC氧化酶(ACO) 在氧氣存在下催化完成。

    3.調控與意義

    4.相關術語

    如需進一步了解具體植物中的合成機制(如蕨類),可參考研究文獻。
