Abstract：
Cadmium (Cd) contamination poses a significant threat to agriculture and human health due to its high soil mobility and toxicity. This review synthesizes current knowledge on Cd uptake, transport, detoxification, and transcriptional regulation in plants, emphasizing the roles of metal transport proteins and transcription factors (TFs). We explore transporter families like NRAMP, HMA, ZIP, ABC, and YSL in facilitating Cd movement within plant tissues, identifying potential targets for reducing Cd accumulation in crops. Additionally, regulatory TF families, including WRKY, MYB, bHLH, and ERF, are highlighted for their roles in modulating gene expression to counteract Cd toxicity. This review consolidates the existing literature on plant-Cd interactions, providing insights into established mechanisms and identifying gaps for future research. Understanding these mechanisms is crucial for developing strategies to enhance plant tolerance, ensure food safety, and promote sustainable agriculture amidst increasing heavy-metal pollution.
摘要：
镉（Cd）污染由于其高度的土壤流动性和毒性而对农业和人类健康构成重大威胁。这篇综述综合了目前关于Cd吸收的知识，运输,排毒,和植物中的转录调控，强调金属转运蛋白和转录因子(TFs)的作用。我们探索像NRAMP这样的转运家族，HMA,ZIP,ABC,和YSL促进Cd在植物组织内的移动，确定减少作物中Cd积累的潜在目标。此外,调节TF家族，包括WRKY,MYB,bHLH,还有ERF,强调了它们在调节基因表达以抵消Cd毒性方面的作用。这篇综述巩固了植物-Cd相互作用的现有文献，提供对既定机制的见解，并确定未来研究的差距。了解这些机制对于制定增强植物耐受性的策略至关重要。确保食品安全,在重金属污染日益严重的情况下促进可持续农业。
