abscisic acid

abscisic acid的音标为["æbsɪsɪsɪk æsɪd]，基本翻译为“脱落酸”，速记技巧为“脱落酸，酸脱叶”。

Abscisic acid 的英文词源可能来自于拉丁语 "absidius"，意为“沉淀物”或“浓缩物”。其名称来源于其最初被发现的特性，即它在植物的休眠和干燥过程中起到的作用。

变化形式：复数形式为 abscisae，过去式和过去分词为 abscised 或 abscised，现在分词为 abscising。

相关单词：

1. Abscission：这个词表示植物的脱落或分离，尤其是指果实和叶片的脱落。

2. Abscisal：这个词缀常用于描述与 abscisic acid 相关的性质或状态。

3. Abscisic acid-related protein (ACR)：与脱落酸相关的蛋白质。

4. Abscission zone：脱落部位，指在植物中负责果实和叶片脱落的区域。

5. Abscisic acid insensitivity：脱落酸不敏感，指某些植物或组织对脱落酸反应不敏感。

6. Abscisic acid-induced：脱落酸诱导的，指由脱落酸引发的反应或过程。

7. Abscisic acid signaling：脱落酸信号传导，指植物体内对脱落酸的反应和调控机制。

8. Abscisic acid-mediated：脱落酸介导的，指通过脱落酸实现的生理功能或过程。

9. Abscisic acid-degrading enzyme：脱落酸降解酶，指能够分解脱落酸的酶。

10. Abscisic acid homeostasis：脱落酸稳态，指植物体内脱落酸含量和分布的平衡状态。

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.
