The complete chloroplast genome of Zelkova serrata and its phylogenetic position within Ulmaceae

Abstract

The complete chloroplast genome sequence of the Tertiary relict tree Zelkova serrata was reported in this study. The chloroplast genome is 158,875 bp in length with a typical angiosperm quantitative structure consisting of a large single copy (87,412 bp) and a small single copy (18,683 bp) separated by a pair of inverted repeat (26,390 bp). Genome annotation revealed a total of 129 genes comprising 84 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenomic analysis based on the whole plastomes indicated that Z. serrata and Z. schneideriana formed a well-supported monophyletic clade sister to genus Ulmus in Ulmaceae.
