Wild watermelon is a drought-resistant plant and accumulates antioxidative amino acid citrulline under stress condition. It is revealed that feedback regulation of AGK by arginine is relaxed by the nitrogen sensor P-II protein. Massive degradation of photosynthetic proteins is enhanced under stress, which serves as the nitrogen source for citrulline biosynthesis. Stress-induced proteases are involved in this degradation process.

野生西瓜是一种耐旱植物，在逆境条件下积累抗氧化氨基酸瓜氨酸。结果表明，精氨酸对AGK的反馈调节被氮传感器P-II蛋白所放松。光合作用蛋白质的大量降解在胁迫下得到增强，这是瓜氨酸生物合成的氮源。应激诱导的蛋白酶参与该降解过程。
