Phylogenomic relationships and molecular convergences to subterranean life in rodent family Spalacidae
All extant species in the rodent family Spalacidae are subterranean and have evolved various traits for underground life.However,the phylogenomic relationships among its three subfamilies (Myospalacinae,Spalacinae,and Rhizomyinae)and the molecular basis underlying their adaptations to underground life remain poorly understood.Here,we inferred the phylogenomic relationships among these subfamilies based on de novo sequencing the genome of the hoary bamboo rat (Rhizomys pruinosus).Analyses showed that～50％ of the identified 11028 one-to-one orthologous protein-coding genes and the concatenated sequences of these orthologous genes strongly supported a sister relationship between Myospalacinae and Rhizomyinae.The three subfamilies diversified from each other within ～2 million years.
