The complete chloroplast genome of ornamental coffee tree, Coffea arabica L. (Rubiaceae)

Abstract

Coffea arabica L. taking 70% of world coffee production is also used as an ornamental species. One imported coffee tree from Indonesia near to thirty years ago of which leaf is wrinkled (named as IN1) was chosen to know its genetic background. Here, we presented complete chloroplast genome of Coffea arabica IN1 which is 155,277 bp long and has four subregions: 85,248 bp of large single copy (LSC) and 18,137 bp of small single copy (SSC) regions are separated by 25,946 bp of inverted repeat (IR) regions including 131 genes (86 protein-coding genes, eight rRNAs, and 37 tRNAs). The overall GC content of the chloroplast genome is 37.4% and those in the LSC, SSC, and IR regions are 35.4%, 31.3%, and 43.0%, respectively. In comparison to three available coffee chloroplast genomes, 84 bp insertion on IN1 chloroplast genome is found, which is big differences in comparison to other available coffee chloroplast genomes. Even though relatively low number of sequence variations on coffee chloroplast genomes, these results can be used as a corner stone for establishing molecular markers to identify its origin or cultivars.
