Complete chloroplast genome sequence and phylogenetic analysis of Ilex viridis Champ. ex Benth

Abstract

Ilex viridis Champ. ex Benth. is domestic to southern China. In the present work, the complete chloroplast (cp) genome sequence of Ilex viridis was assembled and characterized by high-throughput sequencing analyses. The chloroplast genome was 157,701 bp in length, consisting of large single-copy (LSC) and small single-copy (SSC) regions of 87,177 bp and 18,394 bp, respectively, which were separated by a pair of 26,065 bp inverted repeat (IR) regions. The genome was predicted to contain 134 genes, including 89 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The overall GC content of the genome is 37.7%. The phylogenetic tree reconstructed using 13 chloroplast genomes reveals that I. viridis is mostly related to Ilex szechwanensis.
