The plastid genome of Pentadiplandra brazzeana Baillon (Pentadiplandraceae).

Pentadiplandra brazzeana is the only species of Pentadiplandraceae. This species is shrubs or tuberous liana with a natural distribution in tropical West Africa. This study firstly determined its complete plastome. The plastome is totally 156,625 bp in length, which contains a pair of 26,751-bp-long inverted repeat regions (IRs), a large single copy region of 85,318 bp, and a small single copy region of 17,805 bp. A total of 112 unique genes were identified in this plastome, of which 78 are protein-coding genes, 30 are tRNA genes, and 4 are rRNA genes. Phylogenetic analysis based on 82 genes fully resolved relationships among sampled families of Brassicales, which are consistent with previous studies.
