The complete chloroplast genome sequence of Ulmus parvifolia (Ulmaceae).

Ulmus parvifolia Jacq is a kind of landscape tree endemic to East Asia. In this study, the complete chloroplast genome of U. parvifolia was sequenced. The genome was 159,259 bp in length, with a large single-copy (LSC) region of 88,451 bp, a small single-copy (SSC) region of 19,598 bp, and two inverted repeat (IR) regions of 25,605 bp, each. The genome consisted of 121 genes, including 77 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. The phylogenetic results indicated that Ulmus is not monophyletic and U. parvifolia constitute a well-supported clade sister to U. Sect. Ulmus. The complete chloroplast genome of U. parvifolia will provide important information for phylogenetic and evolutionary studies in Ulmaceae, as well as the other closely related families.
