Kosteletzkya pentacarpos is a promising plant being developed as a salt-tolerant biofuel crop that also the ability to fix heavy metals. Here, high-throughput sequencing technology was used to sequence and assemble the chloroplast genome of K. pentacarpos. The full length of the chloroplast genome is 161,777 bp, comprising a large single-copy region of 90,019 bp, a small single-copy region of 18,978 bp, and a pair of inverted repeats of 26,390 bp. A total of 113 genes were annotated, including 79 protein-coding, 30 transfer RNA, and 4 ribosomal RNA genes. Phylogenetic analysis based on whole chloroplast genome sequences showed that K. pentacarpos has a close relationship with Abelmoschus in Malvaceae. This study increases the available genomic information on K. pentacarpos, and provides a basis for the rational exploitation and utilization of germplasm resources.
Keywords: Kosteletzkya pentacarpos; complete chloroplast genome; phylogenetic analysis.
