完整的16S样核糖体RNA编码区获得的真菌共生体的五个属的attine（切叶）蚂蚁和两个自由生活的真菌。利用距离矩阵法、最大似然法和简约法进行系统发育分析，结果表明该共生菌为伞菌目同担子菌。比较的拓扑结构的attine真菌共生体系统发育树与一棵树的基础上attine蚂蚁形态揭示了一个一致的分支模式的更多的衍生attine蚂蚁和它们的真菌共生体。这种平行的分枝模式表明切叶蚁和它们的真菌共生体之间存在着长期的协同进化。
Complete 16S-like ribosomal RNA coding regions were obtained from the fungal symbiont of five genera of attine (leaf-cutting) ants and two free-living fungi. Phylogenetic analyses with distance matrix, maximum likelihood, and parsimony methods revealed that the attine fungal symbionts are homobasidiomycetes in the order Agaricales. Comparison of the topology of the attine fungal symbiont phylogenetic tree with a tree based on attine ant morphology revealed a congruent branching pattern of the more derived attine ants and their fungal symbionts. The parallel branching pattern suggests a long-term coevolution of derived leaf-cutting attine ants and their fungal symbionts.
