Abstract:
Ctenolophon englerianus Mildbr. is endemic to West Africa. The wood of this species is very strong, and is widely used as building material in local regions. In this study, we determined its complete plastome sequence. This is the first reported complete plastome sequence in the family Ctenolophonaceae. The plastome of C. englerianus was found to possess a total length of 161,553 bp containing two inverted repeats (IRs) of 27,469 bp, a large single copy (LSC) region of 89,386 bp, and a small single copy (SSC) region of 17,229 bp. The plastome contains 110 unique genes, consisting of 76 protein-coding genes, 30 tRNA genes and 4 rRNA genes. The rpl32, rps16 and infA genes were lost. To validate the phylogenetic relationships of C. englerianus in Malpighiales, we have selected seven representative families from three major clades of Malpighiales to construct phylogenetic tree. According to the phylogenetic topologies, C. englerianus has a close relationship with Erythroxylum novogranatence.
