脯氨酸是一种蛋白质氨基酸，在胁迫和非胁迫条件下作为植物中的有益溶质积累。最近的研究表明，脯氨酸在植物的生长和分化过程中起着重要的作用。它是许多细胞壁蛋白的关键决定因子，在植物发育中起重要作用。延伸蛋白、阿拉伯半乳聚糖蛋白、羟脯氨酸和脯氨酸丰富的蛋白作为细胞壁蛋白的重要组成部分，在细胞壁信号转导级联、植物发育和抗逆性等方面发挥着重要作用。分子的见解也提供了在这里到脯氨酸转运蛋白调节植物发育中的关键事件的合理作用。此外，脯氨酸在种子发育过程中的作用，包括贮藏蛋白质的合成进行了讨论。
Proline is a proteogenic amino acid and accumulates both under stress and non-stress conditions as a beneficial solute in plants. Recent discoveries point out that proline plays an important role in plant growth and differentiation across life cycle. It is a key determinant of many cell wall proteins that plays important roles in plant development. The role of extensins, arabinogalactan proteins and hydroxyproline- and proline-rich proteins as important components of cell wall proteins that play pivotal roles in cell wall signal transduction cascades, plant development and stress tolerance is discussed in this review. Molecular insights are also provided here into the plausible roles of proline transporters modulating key events in plant development. In addition, the roles of proline during seed developmental transitions including storage protein synthesis are discussed.
