The complete chloroplast genome of Calophyllum soulattri Burm. f. (Calophyllaceae)

Abstract

Calophyllum soulattri Burm. f. (1768) is an evergreen tree native to Southeast Asia, Australia, and the Solomon Islands. It is known for its medicinal uses and has been utilized in traditional folk medicine. However, genomic resources for this species are still unavailable. In this study, we sequenced and assembled the first complete chloroplast genome of C. soulattri using next-generation sequencing data. The chloroplast genome of C. soulattri is 161,381 bp in length with a total GC content of 36.36%. The chloroplast genome contains a large single copy (LSC) region of 88,680 bp, a small single copy (SSC) region of 17,453 bp, and two inverted repeat (IR) regions of 27,624 bp each. Furthermore, the chloroplast genome has 131 genes, which include 86 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Phylogenetic analysis indicated that C. soulattri is clustered in the same branch with C. inophyllum and is closely related to Mesua ferrea.
