昆虫真菌栽培是由蚂蚁、白蚁、甲虫和蚊子进行的，并已被认为在植物蚂蚁中广泛存在。一些从事真菌栽培的昆虫，包括蚂蚁和树皮甲虫，已知使用产生共生抗生素的放线菌来保护自己和他们的真菌品种免受感染。在这项研究中，我们利用16S rRNA的深度测序方法分析了植物蚂蚁属Allmerus和TetRaponera角质层上的细菌群落。别名蚂蚁将木耳作为建筑材料来培养，以加强对猎物的诱捕；而四翼蚁则将木耳作为食物来源。我们报告了Allmer us和TetRaponera微生物群包含>；75%的变形杆菌，并且值得注意的是，尽管它们在地理上分离(分别是南美洲和非洲)，但它们皮肤微生物群中占主导地位的细菌门非常相似。值得注意的是，产生抗生素的放线菌只占等位菌和四射线虫表皮微生物群的一小部分。取而代之的是γ-变形杆菌、欧文氏杆菌和沙雷氏菌。这两个门都已知含有抗生素产生的物种，因此可能在这些蚂蚁-植物系统中发挥保护作用。
Insect fungiculture is practiced by ants, termites, beetles, and gall midges and it has been suggested to be widespread among plant–ants. Some of the insects engaged in fungiculture, including attine ants and bark beetles, are known to use symbiotic antibiotic-producing actinobacteria to protect themselves and their fungal cultivars against infection. In this study, we analyze the bacterial communities on the cuticles of the plant–ant genera Allomerus and Tetraponera using deep sequencing of 16S rRNA. Allomerus ants cultivate fungus as a building material to strengthen traps for prey, while Tetraponera ants cultivate fungus as a food source. We report that Allomerus and Tetraponera microbiomes contain >75% Proteobacteria and remarkably the bacterial phyla that dominate their cuticular microbiomes are very similar despite their geographic separation (South America and Africa, respectively). Notably, antibiotic-producing actinomycete bacteria represent a tiny fraction of the cuticular microbiomes of both Allomerus and Tetraponera spp. and instead they are dominated by γ-proteobacteria Erwinia and Serratia spp. Both these phyla are known to contain antibiotic-producing species which might therefore play a protective role in these ant–plant systems.
