Seeing the forest and the trees: Reconstructing the phylogenetic and intraspecific history of Acleisanthes (Nyctaginaceae) using plastid genomics and targeted sequencing. Acleisanthes A.Gray is a genus of ~16 species with a Chihuahuan Desert center of distribution. To improve resolution of deeper relationships in Acleisanthes, we generated complete plastid genome sequences for most taxa by multiplexing genomic DNAs on an Illumina GAIIx. To evaluate intraspecific variation within the genus, we also sequenced four chloroplast spacer regions and ITS for a broad population sampling of most taxa, including all widely distributed species. We place the results in the context of the assembly of arid- and semiarid-adapted floras in North America, including the assembly of the Chihuahuan Desert gypsum endemic flora, and we discuss the benefits of this dual approach for building a more complete picture of the evolutionary history of a clade.
