The complete chloroplast genome of Lindera pulcherrima var. hemsleyana (Lauraceae).

ABSTRACT: Lindera pulcherrima var. hemsleyana is an evergreen tree of the genus Lindera with important medicinal value. The complete chloroplast genome of L. pulcherrima var. hemsleyana is 152,710 bp in length, containing a LSC region of 93,751 bp, a SSC region of 18,813 bp, and a pair of inverted repeats (IRA and IRB) of 20,073 bp each. The genome encoded 128 genes, including 83 protein-coding genes, 8 ribosomal RNA genes, 36 transfer RNA genes, and one pseudogene (ycf1). Most of these genes occurred in a single copy, whereas 15 genes occurred in double copies, including all rRNA, 6 tRNA, and 5 protein-coding genes. The GC content of the whole genome, LSC, SSC, and IR regions is 39.2%, 38.0%, 33.9%, and 44.4%, respectively. A total of 90 SSRs were discovered, the numbers of mono-, di-, tri-, tetra-, penta-, and hexa-nucleotides SSRs were 66, 10, 4, 8, 1, and 1, respectively. Phylogenetic analysis of cp genomes from 24 species of Lauraceae revealed that cp genomes of L. pulcherrima var. hemsleyana, L. pulcherrima var. attenuata, and L. pulcherrima formed a monophyletic clade with 100% bootstrap value.
