Nitrogen (N) is an essential macronutrient for plants and profoundly affects crop yields and qualities. Ammonium (NH4+) and nitrate (NO3) are major inorganic N forms absorbed by plants from the surrounding environments. Intriguingly, NH4+ is usually toxic to plants when it serves as the sole or dominant N source. It is thus important for plants to coordinate the utilization of NH4+ and the alleviation of NH4+ toxicity. To fully decipher the molecular mechanisms underlying how plants minimize NH4+ toxicity may broadly benefit agricultural practice. In the current minireview, we attempt to discuss recent discoveries in the strategies for mitigating NH4+ toxicity in plants, which may provide potential solutions for improving the nitrogen use efficiency (NUE) and stress adaptions in crops.

减轻植物中的铵毒性

氮 (N) 是植物必需的常量营养素,深刻影响作物产量和品质。铵(NH 4 + )和硝酸盐(NO 3 - )是植物从周围环境中吸收的主要无机氮形式。有趣的是,当NH 4 +作为唯一或主要氮源时,通常对植物有毒。因此,植物协调NH 4 +的利用和NH 4 +毒性的减轻非常重要。全面解读植物如何最大限度减少 NH 4 +的分子机制毒性可能广泛有利于农业实践。在当前的小型综述中,我们尝试讨论减轻植物NH 4 +毒性策略的最新发现,这可能为提高作物氮利用效率(NUE)和逆境适应提供潜在的解决方案。
