摘要:

镉(Cd)是一种分布广泛且污染严重的重金属; 其毒性大, 不仅影响植物的生长发育, 而且危害人类健康。该文对植物Cd胁迫的生理生化响应方面的最新研究进展进行了总结概括。从植物光合系统、活性氧、活性氮、抗氧化防御系统、激素、钙信号、蛋白和基因等方面, 概述了植物对Cd胁迫的响应及应答机制, 探讨了植物对Cd胁迫响应机制的研究方向, 旨在为今后开展植物响应Cd胁迫的生理生化及分子机制研究提供理论依据。

Abstract:

Cadmium (Cd) is one of the widely distributed and polluted heavy metals. With serious toxicity, Cd not only affects the growth and development of plants, but also endangers human health. This review summarizes recent research advances and underlying mechanisms of physiological and biochemical responses to Cd stress in plants. We also review and discuss plant responses in photosynthetic systems, reactive oxygen species and reactive nitrogen species, antioxidant defense systems, hormones, calcium signals, and their underpinning proteomics and genomics mechanisms. We aim to form a theoretical basis for future research on understanding the physiological and biochemical mechanisms of plant responses to Cd stress.
