The complete chloroplast genome sequence of the medicinal plant Fagopyrum dibotrys (Polygonaceae)

Abstract

Chloroplast (cp) genome sequences become a useful popular tool for population and phylogeny in recent reports. Here, the complete chloroplast genome of the Fagopyrum dibotrys has been reconstructed from the whole-genome Illumina sequencing data. The circular genome is 159,325 bp in size, and comprises a pair of inverted repeat (IR) regions of 67,788 bp each, a large single-copy (LSC) region of 84,593 bp, and a small single-copy (SSC) region of 6,944 bp. The total Guanine and Cytosine (GC) content is 38.0%, while the corresponding values of the LSC, SSC, and IR region are 36.3%, 34.5%, and 40.2%, respectively. The chloroplast genome contains 131 genes, including 94 protein-coding genes, eight ribosomal RNA genes, and 29 transfer RNA genes. The Maximum-Likelihood Phylogenetic analysis showed a strong sister relationship with F. tataricum in Polygonaceae. Our findings provide a foundation for further investigation of cp genome evolution in F. dibotrys and other higher plants.
