  • Title: [Effects of Phyllostachys edulis invasion of native broadleaf forest on soil fungal community].
    Author: Li YC, Liang X, Li YF, Wang Q, Chen JH, Xu QF.
    Journal: Ying Yong Sheng Tai Xue Bao; 2016 Feb; 27(2):585-92. PubMed ID: 27396134.
    Abstract:
    To investigate variation of soil fungal community in response to invasion of Phyllostachys edulis into native broadleaf forest, we characterized the community structure and the abundance of fungi in soil under bamboo (BB), mixture forest of bamboo and broadleaf (MF) and broadleaf forest (BL) using terminal restriction fragment length polymorphism (T-RFLP) and real-time quantitative PCR. The results showed that the most obvious difference in the soil fungal community structure was observed between the BB and BF stands, followed by that between the MF and BL. Shannon index and evenness index of soil fungi were higher in the MF than in the BB and BL. pH and NH4+-N content were the most important environmental gradients on the distribution of fungal community under BB, while NO3(-)-N content significantly affected the distribution of the fungal community under BL. The abundance of fungi in BL was significantly higher than that in BB and MF, and the fungi abundance showed a negative correlation with soil pH but a positive correlation with NO3(-)-N content. These results implied that heterotrophic nitrification driven by fungi could occur in soil of BL, and this process might be changed by the bamboo invasion.
