Complete plastid genome of Lespedeza tricolor (Fabaceae), an endemic shrub in Korea.

ABSTRACT: Lespedeza tricolor is a species found in the southern province of Korea, thought to be endemic to Korea. The complete plastid genome of this legume was sequenced in this study. DNA from L. tricolor was extracted, sequenced, and assembled into the complete plastid genome. We used 18 species of the family Fabaceae and 77 protein-coding genes to perform phylogenetic analysis. The plastid genome is 149,038 bp in length, with large (82,495 bp) and small (18,889 bp) single-copy regions, separated by a pair of inverted repeat regions (23,827 bp). It contains 83 protein-coding genes, eight rRNAs, 37 tRNAs, and two pseudogenes (rpl22 and infA). Our phylogenetic analysis suggests that the genus Lespedeza is monophyletic and L. tricolor is closely related to L. maritima and L. buergeri. In this study, we identified the phylogenetic position of L. tricolor and provided the data that can be used in various ways in future studies.

Project description:Various plant species are endemic to the Korean Peninsula, but their evolutionary divergence and establishment are poorly understood. One of these, Lespedeza maritima, has been proposed as either a hybrid (L. cyrtobotrya × L. maximowiczii) or a synonym of L. thunbergii. A distinct taxon, L. uekii, has been proposed for inland populations. We investigated genetic diversity and structure in L. maritima and related taxa to resolve this. Genotypes of L. maritima (n = 244, including L. uekii) were determined using 12 microsatellite loci, then compared with those of related species. Genetic diversity within L. maritima was estimated, and Bayesian clustering analysis was used to represent its genetic structure and that of related taxa. Its distribution during the last glacial maximum (LGM) was predicted using ecological niche modelling (ENM). Neighbour-joining (NJ) analysis and principal coordinate analysis (PCoA) were used to investigate relationships among species. Bayesian tree based on nuclear ribosomal internal transcribed spacers (nrITS) was also reconstructed to show relationships and divergence time among species. Morphological features were examined using flower characteristics. In result, expected heterozygosity (H E) and allelic richness (A R) within L. maritima were higher in southern than northern populations. Bayesian clustering analysis largely assigned populations to two clusters (K = 2) (south vs. north). The ENM showed that L. maritima occurred around the East China Sea and Korean Strait land bridge during the LGM. Compared with other Lespedeza species, L. maritima was assigned to an independent cluster (K = 2-5), supported by the NJ, PCoA, Bayesian tree and morphological examination results. Lespedeza maritima and L. uekii were clustered to one clade on Bayesian tree. Given results, current L. maritima populations derive from post-LGM colonization away from southern refugia. The type L. uekii, which grows inland, is thought synonym of L. maritima. In addition, L. maritima is considered a distinct species, compared with related taxa.
