Abstract

Ehretia dicksonii_Hance 1862 is a deciduous botany of Ehretiaceae. In this work, the complete chloroplast (cp) genome sequence of E. dicksonii was probed by next generation sequencing in an effort to provide genomic resources useful for promoting its conservation. The complete cp genome of E. dicksonii is 156,623 bp in length, including a large single-copy (LSC) region of 86,853 bp, and a small single-copy (SSC) region of 18,150 bp. It contains 133 genes, including 37 tRNA genes, 8 rRNA genes, and 88 protein-coding genes. The overall GC content of E. dicksonii chloroplast genome is 37.85%. The phylogenetic analysis suggests that E. dicksonii is in the clade of Ehretiaceae other than Boraginaceae. Also, E. dicksonii has a close relationship with Ehretia acuminata_Brown 1810 in Ehretiaceae.

Keywords: Ehretia dicksonii; Ehretiaceae; complete chloroplast genome; phylogenomics.
