Patterns and Rates of Plastid rps12 Gene Evolution Inferred in a Phylogenetic Context using Plastomic Data of Ferns.

ABSTRACT: The trans-splicing rps12 gene of fern plastomes (plastid genomes) exhibits a unique structure owing to its variations in intragenic exon location and intron content, and thus, it provides an excellent model system for examining the effect of plastid gene structure on rates and patterns of molecular evolution. In this study, 16 complete fern plastome sequences were newly generated via the Illumina HiSeq sequencing platform. We reconstructed the phylogeny of ferns and inferred the patterns and rates of plastid rps12 gene evolution in a phylogenetic context by combining these plastome data with those of previously published fern species. We uncovered the diversity of fern plastome evolution by characterizing the structures of these genomes and obtained a highly supported phylogenetic framewor
