title: [Genetic diversity of arbuscular mycorrhizal fungi associated with four Alnus species in Changbai Mountains: a nested PCR-rFLP analysis].
abstract: In this paper, the colonization of arbuscular mycorrhizal fungi (AMF) on the root samples of 4 Alnus species in Changbai Mountains was investigated by using nested PCR-RFLP technique, and the PCR results were tested by restriction endonuclease analysis method. The results revealed that the uncultured AMF had a high genetic diversity, and the colonization had a trend from promiscuity to specialization. The AMF from Alnus mandshuica showed the greatest specialization to the host, and Glomus was the dominant colonizer of A. mandshuica. The AMF from A. sibirica var. hirsuta, A. sibirica, and A. tinctoria showed promiscuity, and host had more significant effects on the colonization of AMF than altitude.
