Abstract
The conversion of proline to glutamic acid and hence to other soluble compounds (proline oxidation) proceeds readily in turgid barley (Hordeum vulgare) leaves and is stimulated by higher concentrations of proline. This suggests that proline oxidation could function as a control mechanism for maintaining low cellular levels of proline in turgid tissue. In water-stressed tissue, however, proline oxidation is reduced to negligible rates. These results are consistent with the idea that proline accumulation results from inactivation by water stress of normal control mechanisms. It seems likely that inhibition of proline oxidation is necessary in maintaining the high levels of proline found in stressed barley leaves.
摘要
脯氨酸向谷氨酸进而向其他可溶性化合物的转化（脯氨酸氧化）在膨压充足的大麦（Hordeum vulgare）叶片中很容易进行，并且会受到较高浓度脯氨酸的刺激。这表明脯氨酸氧化可能作为一种控制机制，以维持膨压充足的组织中脯氨酸的低细胞水平。然而，在水分胁迫的组织中，脯氨酸氧化速率降低到可以忽略不计的程度。这些结果与脯氨酸积累是由于水分胁迫使正常控制机制失活这一观点一致。脯氨酸氧化的抑制似乎对于维持胁迫大麦叶片中发现的高水平脯氨酸是必要的。
