Characterization of the complete chloroplast genome of longan ( Lour.) using illumina paired-end sequencing.

Longan ( Lour.), as a kind of commercial fruit tree in the family Sapindaceae, is widely cultivated in South Asia. In this study, we obtained the complete chloroplast genome sequence of longan using Illumina paired-end sequencing. It has 160,833 bp in length, containing a pair of IR regions (28,428 bp) separated by a small single-copy region (18,270 bp) and a large single-copy region (85,707 bp). The overall GC contents of the chloroplast genome were 37.8%. This circular genome contains 130 annotated genes, including 85 protein-coding genes, 37 tRNAs and 8 rRNAs. The phylogenetic analysis using maximum-likelihood (ML) and neighbour-joining (NJ) method showed that longan has the closest relationship with , and This complete chloroplast genomes can be subsequently used for the genetic breeding of this valuable species.
