Abstract

The work focused on the effects of signal molecules of nitric oxide (NO), salicylic acid (SA) and hydrogen peroxide (H(2)O(2)) on compounds of nitric metabolites of free amino acid, soluble protein and proline in tobacco. The results indicated that NO, SA and H(2)O(2) were able to regulate the proline, free amino acid and soluble protein content in tobacco. Lower concentration of NO and H(2)O(2) raised the level of proline; while higher concentration of NO and H(2)O(2) lowered the proline, free amino acid content in tobacco. The above three signal molecules also showed similar effects on proline, free amino acid and soluble protein content in tobacco.

摘要

该研究聚焦于一氧化氮（NO）、水杨酸（SA）和过氧化氢（H₂O₂）等信号分子对烟草中游离氨基酸、可溶性蛋白质和脯氨酸的含氮代谢产物的影响。结果表明，NO、SA和H₂O₂能够调节烟草中脯氨酸、游离氨基酸和可溶性蛋白质的含量。较低浓度的NO和H₂O₂提高了脯氨酸水平；而较高浓度的NO和H₂O₂则降低了烟草中脯氨酸和游离氨基酸的含量。上述三种信号分子对烟草中脯氨酸、游离氨基酸和可溶性蛋白质含量也表现出相似的影响。
