The complete chloroplast genome of Cymbidium hookerianum (Orchidaceae): genome structure and basic analysis.

ABSTRACT: Cymbidium hookerianum Rchb.f. is an ornamental orchid with large flowers and delicate aroma. Here, we reported the complete chloroplast genome sequence of C. hookerianum. The total chloroplast genome cycle was 155,447 bp. It displayed a typical structure including one large single-copy (LSC, 84,186 bp) region, one small single-copy (SSC, 17,839 bp) region, and two inverted repeat (IRs, 26,711 bp). 124 genes (78 CDSs, 38 tRNAs, 8 rRNAs) were encoded by the cp genome. The average GC content of this sequence was 36.8%. The phylogenetic analysis revealed C. hookerianum and C. changningense are sisters. The groundwork of chloroplast genome would provide available reference for molecular taxonomy and breeding.

The genome contains 130 genes, namely 84 protein-coding genes, 38 tRNA genes and 8 rRNA genes. The maximum-likelihood phylogenetic tree has proved that C. longibracteatum should exist as an independent species in the genus Cymbidium, and it is most closely related to C. tortisepalum. This study provides valuable sequence resources for further study of C. longibracteatum.
