Comparative analysis of chloroplast genomes and phylogenetic relationships of different pitaya cultivars.

ABSTRACT:

Background

Pitaya is an important tropical fruit highly favoured by consumers owing to its good and juicy characteristics. It contains a large amount of betacyanin, which is a natural food-colouring agent, in the peel and pulp. However, few studies have focused on the pitaya chloroplast (cp) genomes.

Results

To explore the genetic differences and phylogenetic relationships among the cp genomes of the six pitaya cultivars, we assembled, annotated, and performed a comparative genomic analysis. The cp genomes of the six cultivars exhibited a typical circular structure, ranging in length from 133,146 to 133,617 bp, with a GC content of 36.4%. All individual cp genomes were annotated with 123 genes, including 80 protein-coding genes, 38 tRNA genes, four rRNA genes, and one pseudo
