AbstractSelaginellaceae have been shown to be monophyletic in previous studies, and include only the single genus Selaginella. However, the two most recent classifications of the genus disagree in terms of the number of subgenera recognized, and the position of problematic clades such as the sanguinolenta group, which has been resolved in quite different positions in different studies. Here, we performed a plastid-genome based phylogenomic analysis of Selaginellaceae to address this problem. The sanguinolenta group, represented here by three species, was resolved as sister to the remaining members of subg. Stachygynandrum. Additionally, subg. Exaltatae, subg. Ericetorum, and subg. Gymnogynum in Glade A clustered into a well supported monophyletic Glade but with conflicting topology between subgenera inside, which is possibly attributed to the early divergence among them. We uncovered substantial variation in both synonymous (dS) and nonsynonymous (dN) substitution rate, and GC content in plastomes of Selaginellaceae. The values of dS, dN, and GC content were significantly higher than those of other lycophytes (Isoetaceae and Lycopodiaceae). We observed a significant positive correlation between the high GC content, and the elevated dS and dN rates. In addition, the dS and dN values inferred among branches of Selaginellaceae were extremely variable. Our data indicate that this unevenly distributed substitution rate likely reflected relaxed or intensified selection among different lineages, which is possibly related to the inconsistency of the subgeneric phylogenetic topologies of Selaginellaceae.
