Three complete plastome sequences from the families of Lamiaceae, Mazaceae, and Phrymaceae (Lamiales).

In this study, we report the first complete plastome sequence of (Lamiaceae) (MT937186). In addition, the plastome sequences of subsp. (Phrymaceae) (153,324 bp; MT948145) and (Mazaceae) (152,847 bp; MT937187) are also included. The gene orders and structures of the three plastomes are collinear with those of the typical plastome of angiosperm. The plastome size of is 154,370 bp in length and consists of a large single-copy region of 85,079 bp and a small single-copy region of 17,917 bp, which are separated by a pair of 25,687 bp-long inverted repeat regions. In addition, the plastome sizes of subsp. and are 153,324 bp and 152,847 bp, respectively. The three plastomes contain 113 genes, including 79 protein-coding, 30 tRNA, and four rRNA genes. Sixteen genes contain one intron and two genes have two introns. A total of 41 simple sequence repeat loci was identified in the plastome. Phylogenetic analysis shows that Viticoideae is a sister group of the last of Lamiaceae except Nepetoideae. The Mazaceae are a sister group of Lamiaceae, while Phrymaceae form a sister group to the Paulowniaceae-Orobanchaceae clade.
