Fifteen complete chloroplast genomes of Trapa species (Trapaceae): insight into genome structure, comparative analysis and phylogenetic relationships.

ABSTRACT:

Background

Trapa L. is a floating-leaved aquatic plant with important economic and ecological values. However, the species identification and phylogenetic relationship within Trapa are still controversial, which necessitates the need for plastid genome information of Trapa. In this study, complete chloroplast genomes of 13 Trapa species/taxa were sequenced and annotated. Combined with released sequences, comparative analyses of chloroplast genomes were performed on the 15 Trapa species/taxa for the first time.

Results

The Trapa chloroplast genomes exhibited typical quadripartite structures with lengths from 155,453 to 155,559 bp. The gene orders and contents within Trapa were conservative, but several changes were found in the microstructure. The intron loss of rpl2, also de
