The complete chloroplast genome of Ulmus mianzhuensis with insights into structural variations, adaptive evolution, and phylogenetic relationships of Ulmus (Ulmaceae).

ABSTRACT:

Background

Ulmus mianzhuensis is an endemic tree species in China with high ornamental and economic value. Currently, little is known regarding its genomic architecture, phylogenetic position, or adaptive evolution. Here, we sequenced the complete chloroplast genome (cp genome) of U. mianzhuensis and further compared the variations in gene organization and structure within Ulmus species to define their genomic evolution, then reconstructed the phylogenomic relationship of 31 related Ulmus species to explore the systematic position of U. mianzhuensis and the utility of cp genome for resolving phylogenetics among Ulmus species.

Results

Our results revealed that all the Ulmus species exhibited a typical quadripartite structure, with a large single copy (LSC) region of 87,170 -
