Abstract

Carya illinoinensis is an important nut tree with high economic and ecological values. Here, we presented the complete chloroplast (cp) genome sequence of C. illinoinensis cv. wichita. The whole cp genome is 160,532 bp in length, displaying a typical quadripartite structure with a large single-copy (LSC) of 897,99 bp, a small single-copy (SSC) region of 18,751 bp, and a pair of inverted repeats (IRs) of 25,991 bp. A total of 128 genes were predicted to contain in the whole cp genome, including 83 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The GC contents of the cp genome is 36.19%. Phylogenomic analysis suggested Carya illinoinensis as a sister species of C. cathayensis, C. kweichowensis, and Annamocarya sinensis.

Keywords: Carya illinoinensis; chloroplast genome; phylogeny.
