The complete chloroplast genomes of Trollius farreri and Anemone taipaiensis (Ranunculaceae).

ABSTRACT: Ranunculaceae, with high morphological biodiversity and widely ecological amplitude tolerance, has been considered as a new good model for adaptive evolution study. In this study, two high-quality chloroplast genomes of Ranunculaceae were determined by next-generation sequencing technologies. The plastomes of Trollius farreri and Anemone taipaiensis exhibit a conserved quadripartite structure, with 160,612?bp and 160,214?bp in length, presenting similar GC contents (38% and 37.6%). The chloroplast genome of Trollius farreri contains 131 genes, including 87 protein-coding genes, 8 rRNA, and 36 tRNA genes, while the plastome of Anemone taipaiensis harbours 137 genes, including 93 protein-coding genes, 8 rRNA, and 36 tRNA genes. Phylogenetic tree constructed with 21 plastomes of Ranunculaceae species indicates that Trollius farreri and Anemone taipaiensis are closely related to their congeneric species, respectively. The phylogenetic relationships are inconsistent with the current classification of Ranunculaceae.
