Phylogenomics and structural variations of plastid genomes of the columbine genus (Ranunculaceae).

ABSTRACT: The columbine genus (Aquilegia) contains many species with horticultural and pharmaceutical importance. However, a well-resolved phylogeny for this genus remains lacking owing to recent and rapid radiation. We obtained plastomes of 75 Aquilegia species and six species of other genera in Thalictroideae to reconstruct a robust phylogeny for Aquilegia. Within the phylogenetic framework, we investigated the evolutionary patterns of structural variations in Aquilegia plastomes. We also examined appropriate molecular markers for species identification of this genus. Plastid phylogenomic analyses show that Aquilegia is monophyletic and divided into two major clades and eight subclades, largely in agreement with species geographical distributions. Aquilegia plastomes have copy number variations (C
