Abstract

Ilex × attenuata 'Fosteri' is an important ornamental plant widely distributed in mid-southern China and south-eastern United States. In this study, we assembled the complete chloroplast (cp) genome of I. attenuata by high-throughput sequencing and bioinformatics. The full length of cp genome was 157,833 bp with 37.63% overall GC content, which contained two inverted repeats (IR) of 26,093 bp separated by a large single-copy (LSC) and a small single copy (SSC) of 87,188 bp and 18,459 bp, respectively. The cp genome contained 135 genes, including 88 protein-coding genes, 8 rRNA genes and 39 tRNA genes. Phylogenetic tree showed that the close relationship of three species of Ilex (I. attenuata, I. viridis and I. szechwanensis) in the Aquifoliaceae family.

Keywords: Ilex × attenuata ‘Fosteri’; complete chloroplast genome; phylogenetic analysis.
