The complete chloroplast genome of Cynoglossum amabile Stapf & J. R. Drumm., 1906 (Boraginaceae), a traditional Chinese herbal medicine

Abstract

Cynoglossum amabile Stapf & J. R. Drumm., 1906 is a traditional Chinese herbal medicine from southwest China. To better determine its phylogenetic relatedness to other Boraginaceae species, the chloroplast (cp) genome of C. amabile was sequenced. The complete cp genome of C. amabile is 151,532 bp in length, containing a small single-copy (SSC) region with a length of 17,366 bp, a large single-copy (LSC) region with a length of 82,902 bp, and a pair of inverted repeats (IRs) regions each with a length of 25,632 bp. The overall GC content of the cp genome is 37.4%. The maximum-likelihood phylogenetic tree showed that Bothriospermum zeylanicum (J. Jacq.) Druce, 1917 was closely related to C. amabile.
