The complete chloroplast genome sequence of an endemic species Pearl chestnut (Castanea henryi)

Abstract

Castanea henryi is Pearl chestnut, or the willow-leaved chestnut, which is widely distributed in the warm temperate subtropical climates of China. We determined the complete chloroplast genome sequence for C. henryi using Illumina sequencing data. The complete chloroplast sequence is 160,907 bp in length and contains a pair of 25,689 bp inverted repeats (IRs), a large single-copy (LSC) region of 90,531 bp, and a small single-copy (SSC) region of 18,998 bp. It contains 132 genes, including 102 protein-coding genes, eight ribosomal RNA genes (four RNA species), 46 transfer RNA genes, and two pseudogenes (ycf1 and ndhK). The overall GC content of the whole genome is 36.7%. Phylogenetic analysis based on 21 chloroplast genomes indicates that C. henryi is closely related to Chinese chestnut (C. mollissima) in Fagaceae.
