title: Ectomycorrhizal fungus communities of Quercus liaotungensis Koidz of different ages in a northern China temperate forest.
abstract: Ectomycorrhizal (ECM) fungal communities of Quercus liaotungensis of different ages (seedlings, young trees and mature trees) in the growing seasons (June and September) between 2007 and 2009 were studied in a temperate forest of northern China. A total of 66 ECM fungal taxa were identified based on ECM morphotyping, PCR-RFLP, and DNA sequence data. Of these fungal taxa, 51 were Basidiomycetes (77.3%) and 15 were Ascomycetes (22.7%). Cenococcum geophilum was the dominant species. Thelephoraceae (16 taxa), Sebacinaceae (12 taxa) and Russulaceae (seven taxa) were the most species-rich and abundant ECM fungi, accounting for 19.5%, 17.6% and 8.3% of the total ECM root tips, respectively. Results of multiple response permutation procedure (MRPP) analysis indicated that there were marginally significant effects of tree ages (A = 0.01801, P = 0.054) and growing seasons (A = 0.01908, P = 0.064) on the ECM fungal species composition of Q. liaotungensis in a temperate forest.
