Abstract
Barley (Hordeum vulgare cv Prior) leaves converted l-U-(14)C-arginine to labeled proline. Accumulation of radioactivity in proline was greater in wilted leaves, but only after 9 hours of incubation. As the increase in free proline was detectable after only 3 to 6 hours, it is likely that the observed stimulation of proline labeling represents a result rather than a cause of proline accumulation. Furthermore, the loss of total arginine during water stress was only 10 to 15% of the increase in proline. We conclude that arginine probably contributes less than 1% of the carbon in the expanding proline pool of wilted barley leaves.
摘要
大麦（Hordeum vulgare cv Prior）叶片将 l-U-（14）C-精氨酸转化为标记脯氨酸。在萎蔫叶片中，脯氨酸积累的放射性更高，但这仅在孵育 9 小时后才出现。由于游离脯氨酸的增加在 3 至 6 小时后即可检测到，因此观察到的脯氨酸标记的刺激可能是结果而不是脯氨酸积累的原因。此外，在水分胁迫下，总精氨酸的损失仅占脯氨酸增加量的 10%至 15%。我们得出结论，在萎蔫大麦叶片中不断扩展的脯氨酸库中，精氨酸的碳贡献可能不到 1%。
