The complete chloroplast genome of fragrant plantain lily (Hosta ventricosa)

Abstract

Fragrant plantain lily (Hosta ventricosa) is an ornamental plant and widely cultivated in China due to its environmental adaptability. Here, the complete chloroplast genome of the H. ventricosa has been constructed from the Illumina sequencing data. The circular cp genome is 155,322 bp in size, and comprises a pair of inverted repeat (IR) regions of 24,912 bp each, a large single-copy (LSC) region of 84,113 bp, and a small single-copy (SSC) region of 20,782 bp. The total GC content is 38.0%, while the corresponding values of the LSC, SSC, and IR region are 36.2%, 32.5%, and 43.4%, respectively. The chloroplast genome contains 135 genes, including 88 protein-coding genes, 8 ribosomal RNA genes, and 39 transfer RNA genes. The neighbor-joining phylogenetic analysis showed a strong sister relationship with Hosta capitata in Hosta. Our findings provide a foundation for further investigation of chloroplast genome evolution in ornamental plant Hosta.
