| Whakarāpopotonga: | Ehretiaceae is a family in the order Boraginales. It contains more than 150 species. The Ehretiaceae classification has remained elusive and changed over time from subfamily to family, or vice versa. In this paper, we sequenced, characterized, and analyzed the complete chloroplast (cp) genomes of Ehretia cymosa and Ehretia obtusifolia, and their cp genomes were compared to those of related species. The length of the chloroplast genomes of E. cymosa was 156,328 bp, whereas that of E. obtusifolia was 155,961 bp. Each genome contained 114 genes, including 80 protein-coding genes, 4 rRNA genes, and 30 tRNA genes. Repeat analysis revealed that complement, forward, palindromic, and reverse repeats were present in the chloroplast genomes of both species. Simple sequence repeat analysis showed that the chloroplast genomes of E. cymosa and E. obtusifolia comprise 141 and 139 microsatellites, respectively. Phylogenetic analysis based on Bayesian and maximum likelihood analyses divided the order Boraginales into two well-supported clades. The first clade includes a single family (Boraginaceae), and the second clade includes three families (Ehretiaceae, Cordiaceae, and Heliotropiaceae). This study provides valuable genomic resources and insights into the evolutionary relationships within Boraginales. [ABSTRACT FROM AUTHOR] |
