植物抗重金属胁迫研究进展
|
摘要
土壤重金属污染导致植物重金属积累量增加,重金属对植物产生毒害的同时,植物也会通过避性和耐性机制抵抗重金属的毒害。从根系分泌物、亚细胞结构、螯合作用、渗透调节、抗氧化系统等方面综述了植物抵抗重金属胁迫的研究进展,以期为该领域的深入研究提供参考。
Heavy metal contamination in agricultural soil could cause the accumulation of heavy metals in plants. While plants suffer from toxicity of heavy metals,they could also operate avoidance and tolerance mechanisms to resist heavy metal poisoning. This paper reviewed the research progress on plant resistance to heavy metal stress in terms of root exudates, subcellular structures, chelation,osmoregulation,and antioxidant systems,aiming to provide reference for further research in this field.
