Abstract
Zanthoxylum bungeanum var. pubescensis is a variety species of Z. bungeanum Maxim. that is characterized with small leaf plants and possess high resistant to cold stress among the genus Zanthoxylum. In the current study, the complete chloroplast genome sequences of two different leaf shapes were assembled. One type of leaflets is thin paper, and the color on both sides is obviously different after drying, and the fruit stalk is slender and elongated; the other type of leaflets are the thick paper, the leaf surface and fruit stalk are glabrous, the fruit stalk is thicker, and the lateral veins are recessed on the leaf surface and appear to be cracked. Their circular DNA lengths were all 158,565 bp. Both genomes were made up of a large single-copy (LSC), a small single-copy (SSC), and two inverted repeat (IRs) regions. Each genome encoded 132 genes, including 87 protein-coding, 37 tRNA, and 8 rRNA genes. Phylogenetic analysis indicated that both species were closely related to the congeneric Z. bungeanum.
