The complete chloroplast genome sequence of Seguin chestnut (Castanea seguinii)

Abstract

Castanea seguinii is a Chinese chestnut, also called Seguin chestnut. It is cultivated for its edible nuts by rural people in subtropical regions and in southwestern China. We determined the complete chloroplast genome sequence for C. seguinii using Illumina sequencing data. The complete chloroplast sequence is 161,010 bp in length and contains a pair of 25,701 bp inverted repeats (IRs), a large single-copy (LSC) region of 90,560 bp, and a small single-copy (SSC) region of 19,048 bp. It contains 132 genes, including 103 protein-coding genes, eight ribosomal RNA genes (four RNA species), 46 transfer RNA genes, and one pseudogene (ycf1). The overall GC content of the whole genome is 36.7%. Phylogenetic analysis based on 20 chloroplast genomes indicates that C. seguinii is closely related to Chinese chestnut (C. mollissima).
