Abstract

Lysimachia congestiflora Hemsl. is a perennial herb of Primulaceae. It is mainly distributed in the provinces to the south of the Changjiang River and south of Shanxi, Gansu province and Taiwan. It is a plant that combines medicinal, ornamental, and economic values. To date no study has been carried out on the genome of L. congestiflora. Here, we report and characterize the complete plastid genome sequence of L. congestiflora in order to provide genomic resources useful for promoting its conservation. The complete chloroplast genome of L. congestiflora is 154,505 bp in length with a typical quadripartite structure, consisting of a large single-copy region (LSC, 84,606 bp), a single-copy region (SSC, 17,961 bp), and a pair of inverted repeats (IRs, 25,969 bp). There are 114 annotated genes, including 80 unique protein-coding genes, 4 unique ribosomal RNA genes, and 30 transfer RNA genes. To investigate the evolution status of L. congestiflora, as well as Primulaceae, we constructed a phylogenetic tree with L. congestiflora and other 11 species based on their complete chloroplast genomes. According to the phylogenetic topologies, L. congestiflora was closely related to L. coreana.
