Proline (Pro) accumulation is a common physiological response in many plants in response to a wide range of biotic and abiotic stresses. Controversy has surrounded the possible role(s) of proline accumulation. In this review, knowledge on the regulation of Pro metabolism during development and stress, results of genetic manipulation of Pro metabolism and current debate on Pro toxicity in plants are presented.
脯氨酸(Pro)积累是许多植物对多种生物和非生物胁迫的常见生理反应。脯氨酸积累可能发挥的作用一直存在争议。在本综述中,我们介绍了发育和胁迫过程中脯氨酸代谢调控的相关知识、脯氨酸代谢基因操作的结果以及当前关于植物中脯氨酸毒性的争论。
