Gentiana arethusae Burkill is a perennial herb classified in the Gentianaceae. In this study, the complete chloroplast genome of G. arethusae was sequenced and analyzed. The chloroplast genome is 137,458 bp in length and encodes a total of 116 genes, including 71 protein-coding, 37 tRNA, and eight rRNA genes. The genome has a low GC content of 38.0%. Phylogenetic analysis of the genome of G. arethusae resolved it in a clade with Gentiana obconica and Gentiana veitchiorum. The complete chloroplast genome of G. arethusae will be helpful to study the genetic diversity and phylogenetics of the Gentianaceae., Competing Interests: No potential conflict of interest was reported by the author(s)., (© 2021 The Author(s).

Lilium amoenum E. H. Wilson ex Sealy is classified in Liliaceae, and it is an important ornamental plant with wonderful rose-red color and pleasant rose fragrance. In this study, we sequenced the complete chloroplast genome of L. amoenum by Illumina Hiseq X Ten and PacBio RS technologies. The genome size of L. amoenum is 152,280 bp, and displays a typical quadripartite structure: one large single-copy (LSC, 81,977 bp), one small single-copy (SSC, 17,539 bp), and a pair of inverted repeat regions (IRs, 26,382 bp). The overall GC content was 37.0%. The complete genome contained 131 genes, including 85 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. Phylogenetic analysis showed that L. amoenum is closely related to L. taliense and L. bakerianum . The present study could afford crucial genetic information for further researches on the genus and related genera., Competing Interests: No potential conflict of interest was reported by the authors., (© 2021 The Author(s).

Lilium rosthornii is the perennial herbaceous bulbous plant belonging to the Lily of the Liliaceae, with high ornamental value and medicinal values. In this present study, we sequenced the complete chloroplast genome of Lilium rosthornii by Illumina Hiseq X Ten and PacBio RS technologies firstly. The genome size of L. rosthornii, was 152,242bp, with typical tetragonal structure: one large single-copy (LSC, 81,875 bp), one small single-copy (SSC, 17,553 bp), and a pair of inverted repeat regions (IRs, 26,407 bp). The overall GC content was 37.02%. The complete genome contained 131 genes, including 85 protein-coding genes, 38 tRNA genes, and eight rRNA genes. Phylogenetic analysis placed L. rosthornii under the family Liliaceae., Competing Interests: No potential conflict of interest was reported by the authors., (© 2021 The Author(s).

Lilium nepalense is a useful plant species not only for its showy flowers but also has high medicinal value. In this study, the whole chloroplast genome of L. nepalense was sequenced for the first time. The genome size of L. nepalense , was 152,956bp, with typical tetragonal structure: one large single copy (82,573 bp), one small single copy (17,527 bp), and a pair of inverted repeat regions (IRs, 26,428 bp). The overall GC content was 37.0%. The complete genome contained 131 genes, including 85 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. Phylogenetic analysis showed that L. nepalense was a close relationship between L. leucanthum and L. henryi . Phylogenetic analysis placed L. nepalense under the family Liliaceae., Competing Interests: No potential conflict of interest was reported by the authors., (© 2021 The Author(s).
