abscisic acid的音標為["?bs?s?s?k ?s?d]，基本翻譯為“脫落酸”，速記技巧為“脫落酸，酸脫葉”。

Abscisic acid 的英文詞源可能來自于拉丁語 "absidius"，意為“沉淀物”或“濃縮物”。其名稱來源于其最初被發現的特性，即它在植物的休眠和干燥過程中起到的作用。

變化形式：復數形式為 abscisae，過去式和過去分詞為 abscised 或 abscised，現在分詞為 abscising。

相關單詞：

1. Abscission：這個詞表示植物的脫落或分離，尤其是指果實和葉片的脫落。

2. Abscisal：這個詞綴常用于描述與 abscisic acid 相關的性質或狀態。

3. Abscisic acid-related protein (ACR)：與脫落酸相關的蛋白質。

4. Abscission zone：脫落部位，指在植物中負責果實和葉片脫落的區域。

5. Abscisic acid insensitivity：脫落酸不敏感，指某些植物或組織對脫落酸反應不敏感。

6. Abscisic acid-induced：脫落酸誘導的，指由脫落酸引發的反應或過程。

7. Abscisic acid signaling：脫落酸信號傳導，指植物體內對脫落酸的反應和調控機制。

8. Abscisic acid-mediated：脫落酸介導的，指通過脫落酸實現的生理功能或過程。

9. Abscisic acid-degrading enzyme：脫落酸降解酶，指能夠分解脫落酸的酶。

10. Abscisic acid homeostasis：脫落酸穩態，指植物體內脫落酸含量和分布的平衡狀態。

3. ABA-dependent signaling plays a crucial role in regulating plant growth and development. (中文)

4. ABA biosynthesis and degradation are tightly regulated processes that ensure proper plant adaptation to changing environments. (中文)

5. Plants that lack ABA sensitivity are prone to water loss and may be more susceptible to environmental stress. (英文)

6. By manipulating ABA levels, researchers can influence plant growth and development, leading to novel crop varieties with improved drought resistance or other desirable traits. (英文)

7. ABA is also known to regulate seed dormancy and germination, making it an essential hormone in plant biology. (英文)

英文小作文：

Abscisic acid, a hormone that plays a crucial role in plant growth and development, regulates many aspects of plant life, including seed dormancy, germination, and response to environmental stress. It is produced in response to environmental changes and regulates the growth and development of plants by influencing the expression of genes involved in cell division and differentiation. In addition, ABA regulates stomatal closure, which helps plants conserve water during periods of drought or high temperatures, ensuring their survival in unfavorable environments. Understanding the role of ABA in plant biology is crucial for developing new crop varieties with improved drought resistance and other desirable traits.
