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.
脯氨酸是一种蛋白质氨基酸，在植物中，无论是在胁迫条件还是非胁迫条件下，它都会作为一种有益溶质而积累。最近的研究发现指出，脯氨酸在植物整个生命周期的生长和分化过程中发挥着重要作用。它是许多细胞壁蛋白的关键决定因素，这些细胞壁蛋白在植物发育中起着重要作用。本文综述了伸展蛋白、阿拉伯半乳聚糖蛋白以及富含羟脯氨酸和脯氨酸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反应、植物发育和胁迫耐受性中所起的关键作用。本文还从分子层面深入探讨了脯氨酸转运体在调控植物发育关键事件中可能发挥的作用。此外，还讨论了脯氨酸在种子发育转变过程中的作用，包括贮藏蛋白的合成。
