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.
Highlights
Urticaceae is a large cosmopolitan family containing over 2000 species, which is notable for its high ecological diversity
Relationships within the family have been resolved to some extent by molecular phylogenetic work (Hadiah et al 2008; Wu et al 2013), indicating for example that Cecropiaceae was neither monophyletic nor distinct from Urticaceae
Cecropiaceae was morphologically described by Berg (1978), comprising six genera and all of these are nested within Urticaceae (Hadiah et al 2008; Wu et al 2013; Treiber et al 2016)
