The complete chloroplast genome of fragrant plantain lily

Fragrant plantain lily (Hosta ventricosa) is an ornamental plant and widely cultivated in China due to its environmental adaptability. In a new study, 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.

The findings provide a foundation for further investigation of chloroplast genome evolution in ornamental plant Hosta.
