- 摘要:
- 酸性土壤的一个特点是存在高水平的铝,通过抑制根细胞的伸长与分裂,对植物产生危害,引发的铝毒问题成为全球关注的环境科学热点问题。在陆地生态系统中,85%的维管植物都和丛枝菌根(AM)真菌有着共生关系。AM真菌产生低分子的分泌物、球囊霉素相关蛋白与铝的螯合作用,真菌菌丝对铝的生物吸附,减少了铝的活动和其毒性,调节了植物和土壤铝元素之间的相互作用,增强植物的耐铝性。该研究主要综述了在自然生态系统中耐铝型AM真菌的种类和类型,以及AM真菌在植物缓解铝毒中所起的作用和内在机制。
- Abstract:
- a feature of the acidic soil is a high Aluminum level,Aluminum is harmful to the plant by inhibiting the root cell elongation and division.Thus the Aluminum toxicity becomes the focus of environmental science in the world.In terrestrial ecosystems,85% of the vascular plants had symbiotic relationship with arbuscular mycorrhizal (AM) fungi.AM fungi produced low molecular secretions and glomalinrelated protein that chelated with Aluminum,Fungal hyphae biologically adsorpted Aluminum,reducing the activities of Aluminum and its toxicity,regulating the interaction between plants and Aluminum element of soil,enhancing the plant resistance to Aluminum.This paper reviewed categories and types of AM fungi with resistance to Aluminum,the role of AM fungi alleviated aluminum toxicity of plant and internal mechanism in the natural ecosystem.
