“…Taraxacum officinale (Asteraceae) is a perennial rosetteforming plant, which originated in Europe. First reported in 1920, T. officinale is now found all over the Korean Peninsula (Ryu & Bae, 2012). Taraxacum platycarpum is a native plant in Korea, China and Japan (Korea National Arboretum, 2016;Mitsuyuki et al, 2014).…”

Inter‐ and intraspecific competitive abilities are significant determinants of invasive success and the ecological impact of non‐native plants. We tested two major hypotheses on the competitive ability of invasive species using invasive (Taraxacum officinale) and native (T. platycarpum) dandelions: differential interspecific competitive ability between invasive and native species and the kin recognition of invasive species. We collected seeds from two field sites where the two dandelion species occurred nearby. Plants were grown alone, with kin (plants from the same maternal genotype) or strangers (plants from different populations) of the same species, or with different species in a growth chamber, and the performance at the early developmental stage between species and treatments was compared. The invasive dandelions outcompeted the native dandelions when competing against each other, although no difference between species was detected without competition or with intraspecific competition. Populations of native species responded to interspecific competition differently. The effect of kinship on plant performance differed between the tested populations in both species. A population produced more biomass than the other populations when grown with a stranger, and this trend was manifested more in native species. Our results support the hypothesis that invasive plants have better competitive ability than native plants, which potentially contributes to the establishment and the range expansion of T. officinale in the introduced range. Although kin recognition is expected to evolve in invasive species, the competitive ability of populations rather than kinship seems to affect plant growth of invasive T. officinale under intraspecific competition.

“…A sample of C. ambigua and two specimens of C. juncea and C. canescens were also included in the analyses as putative parents. Fifteen ISSR primers (Dogan et al 2007, Escaravage et al 2011, Ryu and Bae 2012 were used to generate the data (Supplementary material Appendix 1 Table A2). ISSR PCR conditions optimized for Chondrilla species are described in detail elsewhere (Kashin et al 2017).…”

We studied genetic diversity in 54 populations of nine sexual and apomictic species of the genus Chondrilla (C. acantholepis, C. ambigua, C. brevirostris, C. canescens, C. graminea, C. juncea, C. laticoronata, C. latifolia and C. pauciflora) in SE European Russia and neighboring territories of NW Kazakhstan. We analysed the trnT-trnF region of plastid DNA and the internal transcribed spacer of ribosomal DNA (ITS1-5.8S-ITS2) using statistical parsimony, maximum likelihood and neighbor net methods. Two major evolutionary lineages, roughly corresponding to the two subgenera traditionally recognized in the region, were revealed. Within the first evolutionary lineage (subgenus Brachyrhynchus), the sexual diploid C. ambigua and its putatively hybrid apomictic derivatives C. brevirostris, C. laticoronata and C. pauciflora could be recognized. Their identity was also confirmed by analyses of ISSR markers. The second evolutionary lineage (subgenus Chondrilla) comprises C. juncea, C. acantholepis, C. canescens, C. graminea and C. latifolia in European Russia, but analyses of morphological variability and the genealogy of plastid and nuclear markers favor their treatment as the single facultatively apomictic species C. juncea. The results demonstrate that an apomictic mode of reproduction does not necessarily result in the formation of genetically separated microspecies.

-The morphological characteristics and genetic relationships among 32 germplasms of Zanthoxylum schinifolium and Zanthoxylum piperitum collected from two farms in Korea were investigated. The traits with the most variability were seed color, leaf size, and spine size. The intraspecific polymorphism of Z. schinifolium and Z. piperitum was 96.5% and 60.3%, respectively. The genetic diversity and Shannon's information index values ranged from 0.11 to 0.33 and 0.19 to 0.50, with average values of 0.26 and 0.42, respectively. Two ISSR primers (UBC861 and UBC862) were able to distinguish the different species. The genetic similarity matrix (GSM) revealed variability among the accessions ranging from 0.116 to 0.816. The intraspecific GSM for Z. schinifolium and Z. piperitum was 0.177-0.780 and 0.250-0.816, respectively. The GSM findings indicate that Z. schinifolium and Z. piperitum accessions have high genetic diversity and possess germplasms qualifying as good genetic resources for cross breeding. The clustering analysis separated Z. schinifolium and Z. piperitum into independent groups, and all accessions could be classified into three categories. Z. Schinifolium var. nermis belonged to independent groups. Comparison of the clusters based on morphological analysis with those based on ISSR data resulted in an unclear pattern of division among the accessions. The study findings indicate that Z. schinifolium and Z. piperitum accessions have genetic diversity, and ISSR markers were useful for identifying Z. schinifolium and Z. piperitum.
