白蚁是为数不多的向大气排放甲烷的节肢动物之一，由于白蚁在地球上拥有巨大的生物量，甲烷是全球温室气体的重要来源。本研究以16S rRNA基因为基础，对来自不同谱系的五种白蚁的系统发育多样性进行了分析。与木食性低等白蚁伴生的古生菌在甲烷杆菌目中是唯一的甲烷短杆菌。在NasutiterMessp中也发现了这种类型的产甲烷菌。和微型计算机消息。但在培养真菌的白蚁Odontotermes formosanus和Macrotermes barneyi中则不是这样，它们的肠道中含有甲烷原质目和甲烷肉质目的古细菌。取材较高的白蚁的古细菌多样性高于取材较低的白蚁。古生物多样性最高的是NasutiterMessp。除了隶属于甲烷细菌目、微生物甲烷目和甲烷原质目的产甲烷菌外，37%的古生物克隆属于非产甲烷的塔姆考古纲。本研究结果对进一步了解肠道微生物区系与白蚁的共生关系具有重要意义。
Termites are among the few arthropods that emit methane to the atmosphere, which is a significant source of global greenhouse gas due to their huge biomass on earth. In this study, phylogenetic diversity of Archaea of five termite species from different lineages were analyzed based on 16S rRNA genes. Archaea associated with wood‐feeding lower termite,R. chinensiswere exclusivelyMethanobrevibacterin the order Methanobacteriales. This type of methanogens was also found inNasutitermessp. andMicrocerotermessp. but not in the fungus‐cultivating termites,Odontotermes formosanusandMacrotermes barneyi, which harbor Archaea of the order Methanoplasmatales and Methanosarcinales in their guts. Archaeal diversity of wood‐feeding higher termites was higher than wood‐feeding lower termites. The highest archaeal diversity was found inNasutitermessp. In addition to methanogens affiliated with the orders Methanobacteriales, Methanomicrobiales, and Methanoplasmatales, 37% of archaeal clones were affiliated with non‐methanogenic Thaumarchaeota. The results of this study will be significant for further understanding of symbiotic relationship between intestinal microbiota and termites.
