Fungi are important compartments of microbial communities of mangroves. Their diversity might be influenced by their habitat environment. This study analyzed the distribution and function of fungal communities in the sediments and plant samples from mangrove ecosystem of the Maowei Sea area in Guangxi, China. The results showed that phytopathogenic fungi Cladosporium (17.00%) was mainly observed in the sediments from the protected zone, while endophytic fungi Alternaria (9.22%) and Acremonium (6.09%) were only observed in the sediments from wharf. The fungi in the sediments from village and park were mainly consisted of high-activity endophytes and fungi related to lignin-degrading, respectively. Acaulospora and Aspergillus with higher relative abundance discovered in plant tissues could help plant growth. Cirrenalia (37.66%) and Lignincola (26.73%) with high-activity for lignin-degrading were discovered in decayed leaves. The distribution and function of fungi were highly dependent on the environment settings, thus the fungi can be used as indicators for monitoring the environmental change of mangrove ecosystems.
真菌是红树林微生物群落的重要组成部分。它们的多样性可能受到其栖息地环境的影响。本研究分析了中国广西茅尾海红树林生态系统沉积物和植物样本中真菌群落的分布和功能。结果表明，在保护区的沉积物中主要观察到植物病原菌真菌链格孢（Cladosporium）（17.00%），而在码头的沉积物中仅观察到内生真菌交链孢（Alternaria）（9.22%）和节菱孢（Acremonium）（6.09%）。来自村庄和公园的沉积物中的真菌主要由高活性内生菌和与木质素降解有关的真菌组成。在植物组织中发现相对丰度较高的无梗囊霉属（Acaulospora）和曲霉属（Aspergillus）有助于植物生长。在腐朽叶片中发现了具有较高木质素降解活性的Cirrenalia（37.66%）和木聚糖菌属（Lignincola）（26.73%）。真菌的分布和功能高度依赖于环境设置，因此真菌可以用作监测红树林生态系统环境变化的指标。
