Complete chloroplast genome of ornamental orchids Eulophia flava

Abstract

Eulophia flava (Lindl.) Hook.f. (Orchidaceae) is a high value ornamental plant especially for cutting flowers in China. In this paper, we reported and characterized the complete chloroplast genome sequence of E. flava by assembling from short reads generated by Illumina sequencing. Total chloroplast genome size was 148,903 bp, including inverted repeats (IRs) of 26,651 bp, separated by a large single copy (LSC) and a small single copy (SSC) of 84,465 and 13,132 bp, respectively. A total of 119 genes, including 36 tRNA, 8 rRNA, and 75 protein-coding genes, were identified. The GC content of E. flava is 36.8%. Phylogenetic analysis using the maximum-likelihood algorithm showed that E. flava is sister to a clade with one species in the genus Eulophia.
