Research Progress in Acidobacteria Diversity in Forest Soil
-
摘要: 酸杆菌门(Acidobacteria)是基于分子生态学研究划分的新细菌类群，是最主要的土壤微生物类群之一。它在土壤中广泛分布，所以人们推测它在森林生态系统中具有特定的驱动作用及生态功能。文中综述了国内外关于Acidobacteria多样性的研究进展以及环境因子(海拔、土壤pH值以及土壤中的C和N含量)变化对其多样性的影响，并根据已有研究结果对酸杆菌门的作用进行推测；分析了Acidobacteria目前研究状况的缺失与不足；建议在未来研究工作应针对优势菌群展开，并且侧重于构建不同环境下酸杆菌门的分离培养体系，以期为该菌门的生态功能研究提供参考。Abstract: The Acidobacteria as a new bacterial phylum defined based on molecular ecology is one of the most important soil microbial phylum.It is widely distributed in the soil, which suggests that it has a specific driving action and ecological function in the forest ecosystem.This paper reviewed the research progress in Acidobacteria diversity and the environment factors (altitude, pH value and C and N available in soil) affecting the diversity, and speculated the functions of Acidobacteria.Finally, the insufficiency in recent studies on Acidobacteriathe was analyzed.It is suggested that the future studies in this regard should focus on the dominant Acidobacteria subgroup and build a system of Acidobacteria isolation and incubation under different environmental conditions, which will be of the certain reference value.
