粘细菌是土壤中大量存在的微型捕食者，是一种多细胞的社会性细菌，能产生多种次生代谢产物。捕食者和猎物种群之间的相互作用是土壤微生物食物网的重要组成部分，预计这将塑造微生物群落的组成和动态。在这里，我们假设细菌丰度和群落组成对土壤粘细菌群落的调节。野外调查结果表明，华南亚热带和热带森林土壤中粘球菌的相对丰度为16 SrRNA基因序列的1.49 - 4.74%，粘细菌群落组成在亚热带和热带森林中存在差异。典范对应分析和变异分配分析表明，生物因子（细菌群落组成）对粘细菌变异的解释力略强于土壤性质（土壤pH和有机质）。基于根际细菌网络的温室围隔实验表明，除盐藻科和多囊藻科的部分节点与放线菌和类放线菌的革兰氏阳性细菌相互作用外，大部分粘细菌与革兰氏阴性细菌相互作用。我们推测粘细菌对特定细菌类群的优先捕食可以解释细菌对粘细菌群落的影响。进一步的研究证实了粘细菌捕食的生物学过程是必要的，以促进对微生物世界中捕食行为的生态学作用的理解。
Myxobacteria are abundant micropredators in soil, and are social bacteria with multicellular behavior and producers of versatile secondary metabolites. The interaction between predator and prey populations is an important component in the soil microbial food web, and this is expected to shape the composition and dynamics of microbial communities. Here we hypothesize the regulation of bacterial abundance and community composition on soil myxobacterial community. Field investigation indicated that the relative abundance of Myxococcales in subtropical and tropical forest soil from South China was 1.49−4.74% of all the 16S rRNA gene sequences, and myxobacterial community composition differed between subtropical and tropical forest. The canonical correspondence analysis and variation partitioning analysis indicated that biotic factor (bacterial community composition) showed slightly stronger explanation for variation of myxobacteria than soil properties (soil pH and soil organic matter). Based on the rhizosphere bacterial network, the greenhouse mesocosm experiment showed that most of the myxobacterial links were with Gram-negative bacteria, except that some nodes from Haliangiacea and Polyangiaceae interacted with actinomycetes and actinomycetes-like Gram-positive bacteria. We inferred that myxobacteria preferential predation on specific bacterial taxa may explain the influence of bacteria on myxobacterial community. Further study confirming the biological process of myxobacterial predation in situ is necessary to advance the understanding of the ecological role of predation behavior in the microbial world.
