Abstract

Cymbidium tracyanumvar 'huanghua' × Cymbidium fabericv 'huanghui' is a hybrid species with important ornamental value. In the research, Illumina high-throughput sequencing technologies was used to sequence the chloroplastic genome of Cymbidium tracyanumvar 'huanghua' × C. fabericv 'huanghui'. The genome features of Cymbidium tracyanumvar 'huanghua' × C. fabericv 'huanghui' and the phylogenetic relationships were reported and established. The total length of the complete chloroplast genome is 154,741 bp, consisting of a pair of inverse duplication regions 26,968 bp, a large single-copy region 84,410 bp and a small single-copy region 16,395 bp. The complete genome contains 73 protein-coding genes (PCGs), The entire genome contains 73 genes that encode proteins, 30 tRNA genes and 4 rRNA genes. The phylogenetic tree revealed that Cymbidium tracyanumvar 'huanghua' × C. fabericv 'huanghui' is more closely related to Cymbidium erythraeum.

Keywords: Cymbidium tracyanum var ‘huanghua’×Cymbidium faberi cv ‘huanghui’; Endangered species; chloroplast genome; phylogenetic analysis.
