abscisic acid的音標(biāo)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(lái)自于拉丁語(yǔ) "absidius"，意為“沉淀物”或“濃縮物”。其名稱來(lái)源于其最初被發(fā)現(xiàn)的特性，即它在植物的休眠和干燥過(guò)程中起到的作用。

變化形式：復(fù)數(shù)形式為 abscisae，過(guò)去式和過(guò)去分詞為 abscised 或 abscised，現(xiàn)在分詞為 abscising。

相關(guān)單詞：

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

2. Abscisal：這個(gè)詞綴常用于描述與 abscisic acid 相關(guān)的性質(zhì)或狀態(tài)。

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

4. Abscission zone：脫落部位，指在植物中負(fù)責(zé)果實(shí)和葉片脫落的區(qū)域。

5. Abscisic acid insensitivity：脫落酸不敏感，指某些植物或組織對(duì)脫落酸反應(yīng)不敏感。

6. Abscisic acid-induced：脫落酸誘導(dǎo)的，指由脫落酸引發(fā)的反應(yīng)或過(guò)程。

7. Abscisic acid signaling：脫落酸信號(hào)傳導(dǎo)，指植物體內(nèi)對(duì)脫落酸的反應(yīng)和調(diào)控機(jī)制。

8. Abscisic acid-mediated：脫落酸介導(dǎo)的，指通過(guò)脫落酸實(shí)現(xiàn)的生理功能或過(guò)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(wěn)態(tài)，指植物體內(nèi)脫落酸含量和分布的平衡狀態(tài)。

常用短語(yǔ)：

1. abscission of leaves

2. ABA levels

3. ABA-dependent signaling

2. ABA levels are often elevated in response to environmental stress, such as drought or high temperatures. (中文)

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.
