The complete chloroplast genome sequence and phylogenetic analysis of <i>Viola grayi</i> (Violaceae).

ABSTRACT: Viola grayi, a caulescent species in subsection Rostratae, adapted to coastal dunes, with leathery leaves, is here reported with its first sequenced complete chloroplast genome (158,408 bp), comprising a large single-copy (86,662 bp), a small single-copy (17,994 bp), and pair of inverted repeats (26,876 bp each). Phylogenetic analysis of 22 Viola species, based on a 184,817 bp whole-plastome alignment, resolved the genus as monophyletic and placed V. grayi in a clade with V. grypoceras (BP = 100). This plastome provides a valuable genomic resource for future comparative, taxonomic, phylogenetic, and evolutionary studies.
