Soil is gradually becoming the main sink of metal-based nanomaterials (MNMs) in the environment. Plants, as a vital component in the ecosystem, play a critical role in determining the fate of nanomaterials. Previous studies showed that MNMs could affect the growth and development of various plant species via altering protein expression. In this review, we described the differences in plant protein expression caused by various typical MNM stresses, and summarized the impact factors including physicochemical properties of MNMs, plant characteristics and stress conditions on plant protein response under the stress of MNMs. Moreover, the response mechanisms of plant protein to MNMs stress were reviewed, including energy synthesis and metabolic response, amino acid synthesis and information transmission response, and oxidative stress and defense response. Finally, further research directions were proposed.土壤已逐渐成为金属纳米材料在环境中的主要沉积库,植物作为生态系统中的重要组成部分,在纳米材料的归趋中起着十分重要的作用。研究表明,金属纳米材料会通过改变植物蛋白质的表达影响植物的生长发育。本文阐述了多种典型金属纳米材料胁迫引起的植物蛋白质组差异表达,总结了金属纳米材料胁迫下纳米材料理化性质、植物特征和胁迫条件等因素对植物蛋白质组响应的影响,综述了植物蛋白质组对金属纳米材料胁迫的响应机制,主要涉及能量合成与代谢响应、氨基酸合成与信息传导响应、氧化应激和胁迫防御响应,并对今后的研究方向进行了展望。. |
