丛枝菌根真菌对植物抗寒性影响的研究进展

摘要

Arbuscular mycorrhizal fungi plays an important role in improving absorption of nutrients and growth of plants,it also improves the stress resistance of plants.In order to systematically learn the chilling resistance mechanism of AM fungi and provide a theoretical basis for avoiding freeze injury,species introduction from the south to the north and cold-resistant breeding,the author gives a general statement about the present development of arbuscular mycorrhizal on chilling-resistant mechanisms of plants at home and abroad,and it deals mainly with the relations between the chilling-resistance of AMF plants and absorption of mineral elements,morphological changes,psychological responses and chilling-resistant gene expression.%丛枝茵根真菌接种植物后,能够促进植物养分的吸收和植株的生长,提高植物的抗逆性.为了系统认识AM真菌提高植物抗寒性的机理,为植物避免冻害、南种北引、抗寒育种等提供理论依据,从AM真菌对宿主植物矿质元素吸收、形态结构、生理生化、基因表达等4个方面就国内外对丛枝菌根提高植物的抗寒性研究进行了综述.
