Characterization of the complete chloroplast genome of Carallia diplopetala (Rhizophoraceae)

Abstract

Carallia diplopetala (Rhizophoraceae) is an important economic tree species narrowly distributed endemic to East Asia. In this study, We generate the complete chloroplast genome of C. diplopetala using next-generation sequencing technology, which is 162,052 bp in size and consists of a large single copy (LSC) of 89,556 bp and a small single copy (SSC) of 18,814 bp, separated a pair of inverted repeats (IRb and IRa) of 26,841 bp. The overall GC content is 36.4%. A total of 130 genes are annotated, including 83 protein-coding genes, 37 tRNAs, eight rRNAs and two pseudogenes (ψycf1 and ψrps19). The phylogenetic analysis indicated that C. diplopetala and C. brachiate formed a monophyletic clade with strong support and then sister to Pellacalyx yunnanensis. The plastome of C. diplopetala will provide informative genomic resources for further conservation applications.
