Abstract

The complete chloroplast genome (plastome) of Maclura tricuspidate Carriere, a thorny and deciduous tree, is determined. The plastome is 161,348 bp in length, consisting of a 89,364 bp large single-copy region, a 20,246 bp small single-copy region, and two 25,869 bp inverted repeat regions. The GC content of this plastome is 36.1%. A total of 112 unique genes are annotated for the plastome of M. tricuspidata, containing 78 protein coding genes (PCGs), 30 tRNAs, and four rRNAs. Phylogenetic analysis shows that M. tricuspidata is sister to the clade comprising Dorstenieae, Castilleae, and Ficeae.

Keywords: Maclura tricuspidata; phylogenomics; plastome.
