磷在土壤中易被固定沉淀,在植物磷利用率低的情况下,过度施肥会造成磷肥浪费,可能通过地表径流、地下水溶解等方式,造成水体富营养化产生面源污染,对人类生产生活造成较大影响。丛枝菌根真菌(arbuscular mycorrhizal fungi,AMF)和植物结合所形成的共生菌根可以显著增强植株对磷的吸收利用。通过AMF可以提高宿主植株对磷的吸收转运的特性,从AMF促进植株对磷元素的摄取机制、AMF促进植物磷摄取分子机理、AMF作用下根系分泌物对植株磷利用的影响与根际微生物对AMF磷元素利用的影响4个方面的研究进展进行分析总结。AMF可以通过改变宿主植株的根系形态和菌丝网络的形成,扩大植株对养分吸收范围;释放有机酸、磷酸酶和质子等根系分泌物改变土壤结构和理化性质,与根际微生物共同作用降解土壤中难溶性磷酸盐;诱导相关磷转运蛋白基因的特异性表达,提高植株对磷的转运能力而促进其吸收。 |

Phosphorus is easy to be fixed and precipitated in the soil.Under the condition of low phosphorus utilization rate of plants,over-fertilization will lead to waste of phosphorus fertilizer,which may lead to eutrophication of water body and non-point source pollution through surface runoff,groundwater dissolution, etc.,which has a great impact on human production and life.Combining arbuscular mycorrhizal fungi (AMF)with plants,the symbiotic mycorrhizal fungi formed could significantly enhance the uptake and utilization by plants.This paper analyzes and summarizes the research progress in four aspects:the mechanism of AMF promoting plant phosphorus uptake,the molecular mechanism of AMF promoting plant phosphorus uptake,the influence of root exudates under the action of AMF on plant phosphorus utilization,and the influence of rhizosphere microorganisms on AMF phosphorus utilization.AMF can expand the range of nutrient uptake by plants by changing the root morphology of host plants and the formation of mycelium network; The release of organic acids,phosphatases,protons and other root secretions changed the soil structure and physicochemical properties,and decreased the solubility of insoluble phosphate in the soil under the combined action of rhizosphere microorganisms;Specific expression of related phosphorus transporter genes was induced to improve the ability of phosphorus transport in plants and promote their absorption. |
