Advances in proteomic research on plant responses to metal-based nanomaterial stress

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.
