The complete chloroplast genome sequence and phylogenetic analysis of Ilex 'Beryl', a hybrid of Ilex cornuta × Ilex latifolia (Aquifoliaceae).

Ilex 'Beryl' is an ornamental and ecological tree widespread in southeastern China. In this study, the complete chloroplast (cp) genome of Ilex 'Beryl' was assembled and characterized to investigate its phylogenetic relationship. The entire cp genome of 'Beryl' was a typical quadripartite structure with 157,575 bp in length, including a large single-copy (LSC) region of 87,080 bp and a small single-copy (SSC) region of 18,427 bp, which were separated by a pair of inverted repeats (IRs) of 52,068 bp. There are 135 genes annotated, including 90 protein-coding genes, eight rRNA genes and 37 tRNA genes. Phylogenetic analysis based on whole cp genome sequences showed that 'Beryl' is closest to I. 'Emily Bruner' and I. 'tall boy'.
