【目的】研究降香黄檀心材和边材中真菌群落结构和多样性及其与木材内环境因子的关系,为降香黄檀内生真菌价值评价和资源利用提供依据,为指导降香黄檀人工促进心材形成提供参考。【方法】采用高通量测序技术,结合木材理化性质,研究降香黄檀心材和边材内生真菌的群落结构和多样性,并采用方差分析、冗余分析等手段分析其与降香黄檀内环境因子的关系。【结果】经过高通量测序,共获得2 193 336条序列,碱基总数为761 438 850 bp,有效序列平均长度为385 bp。得到3 621个OTUs,分属26纲67目116科167属186种。纲水平上,心材内生真菌优势菌群为伞菌纲、粪壳菌纲和散囊菌纲,边材内生真菌优势菌群为粪壳菌纲...

Objective: This paper aims to study the diversity of the fungus community structure in heartwood and sapwood of Dalbergia odorifera, and their relationship with the internal environmental factors, in order to provide a basis for the evaluation of endophytic fungi and resource utilization in the trunk of D. odorifera, and further to provide a theoretical basis for artificially promoting the formation of heartwood of D. odorifera. Method: High-throughput sequencing technology was used to study the community structure and diversity of endophytic f...
