摘  要:Maize plants are well colonized with arbuscular mycorrhizal fungi (AMF), which contribute mineral nutrients absorption from soil. However little is known about their role in nitrogen (N) absorption especially from amino acids, which reach a considerable quantity in soils. This experiment was conducted to investigate N acquisition from amino acids through AMF symbiosis. AMF inoculation clearly increased the N content of maize supplied with amino acids (Glu, Ala and Pro). Further study of xylem sap revealed that the composition of amino acids was changed by AMF inoculation. These results indicate that AMF contribute N from amino acids, and may affect the nitrogen assimilation of host plants.Maize plants are well colonized with arbuscular mycorrhizal fungi (AMF), which contribute mineral nutrients absorption from soil.
