Abstract

The complete chloroplast genome of Cecropia pachystachya Trécul was determined in this study. The total genome size was 153,925 bp in length, containing a pair of inverted repeats (IRs) of 25,443 bp, which were separated by large single copy (LSC) and small single copy (SSC) of 84,947 bp and 18,092 bp, respectively. The GC contents is 36.5%. A total of 112 unique genes were annotated, including 30 tRNA, four rRNA, and 78 protein-coding genes. This is the first report of a cp genome for the formerly recognised family Cecropiaceae, and it confirmed that Cecropia pachystachya belongs within Urticaceae.
