“…In general, marginal populations of plant species exhibit significantly reduced within-population genetic variability and increased among-population differentiation relative to geographically central populations (reviewed in Eckert et al, 2008). This might be the consequence (Chang et al, 2016) and in Republic of Korea (12 open circles and four localities in a closed square) (Cheon et al, 2009; the present study), and the 10 sampled populations (closed circles) from four localities (a "locality" is a group of adjacent populations within an administrative boundary) in Yanggu County, Kangwon Province, Republic of Korea. HAN: Hanjeon Rural village; DOS: Dosa Rural village; DGR: Deokgok Rural village; YIM: Yimdang Rural village.…”

“…about three years and half after a fire affected the whole locality. Density of individuals in HAN locality was relatively high until 2009 (Cheon et al, 2009), when it started to decrease due to more shade conditions produced by the growth of broadleaved deciduous trees such as oaks and ashes (J. M. Chung, pers. comm.).…”

“…In North Korea (the Democratic People's Republic of Korea, hereafter the "DRPK"), about 11 localities are known in one city and four counties (Ra et al, 2005;Chang et al, 2016; Fig. 1), whereas in South Korea (the Republic of Korea, hereafter the "ROK"), up to 16 localities have been found to date in one city and four counties, all in Kangwon Province (Cheon et al, 2009, and the present study; Fig. 1).…”

“…It has been generally agreed that demographic and genetic information of endangered plant species is essential for formulating comprehensive conservation strategies (Falk & Holsinger, 1991;Hamrick & Godt, 1996). Although several short-term ecological and demographic surveys have been conducted for S. koreensis in ROK (Cheon et al, 2009;Oh et al, 2009), levels of genetic diversity at regional (e.g. ROK) or species levels are currently not well understood.…”

Low LeveLs of aLLozyme variation in the southern popuLations of the Korean endemic shrub Sophora koreenSiS (fabaceae): impLications for conservation.-We investigated allozyme variation of the rare shrub Sophora koreensis in Yanggu County (South Korea), at the southern margin of the species range. To gain insights into ecological processes at the landscape level, we studied two or three populations from four localities (in total, 10 populations) in a range of ca. 6 km. We found low levels of within-population genetic variation (%P = 13.6, A = 1.14, and H e = 0.026) and a moderate degree of among-population genetic differentiation (F ST = 0.203). The analysis of molecular variance (AMOVA) revealed a substantially higher percentage of variation among populations within localities (17%) than among localities (5%). There was no significant relationship between pairwise genetic divergence and logarithm of pairwise geographic distance (r = 0.032, P = 0.842). These results suggest limited gene flow between populations within localities, while indicating that the optimal strategy for the preservation of the genetic variation of S. koreensis is to conserve as many populations as possible.Key words: allozymes; conservation; genetic diversity; Korea; Sophora koreensis. Resumen bajos niveLes de variación isoenzimática en Las pobLaciones sureñas deL arbusto endémico de corea Sophora koreenSiS (Fabaceae): impLicaciones para su conservación.-Se investigó la variación isoenzimática del arbusto raro Sophora koreensis en el condado de Yanggu (Corea del Sur), en el extremo sur de su área de distribución. Para obtener información sobre los procesos ecológicos a nivel del paisaje, se estudiaron dos o tres poblaciones para cada una de las cuatro localidades (en total, 10 poblaciones) en un radio de unos 6 km. Se encontraron bajos niveles de variación genética intra-poblacional (%P = 13,6, A = 1,14 y H e = 0,026) y un grado moderado de diferenciación genética entre poblaciones (F ST = 0,203). El análisis de la varianza molecular (AMOVA) reveló un porcentaje sustancialmente mayor de variación entre poblaciones dentro cada una de las localidades (17%) que entre localidades (5%). No hubo una relación significativa entre la divergencia genética y el logaritmo de la distancia geográfica entre pares de poblaciones (r = 0,032, P = 0,842). Estos resultados sugieren un flujo genético limitado entre poblaciones dentro de las localidades, además de indicar que la mejor estrategia para la preservación de la diversidad genética de S. koreensis es la conservación del máximo número de poblaciones posible.Palabras clave: conservación; Corea; diversidad genética; isoenzimas; Sophora koreensis. INTRODUCTIONSophora koreensis Nakai (Fabaceae), endemic to the Korean Peninsula, is a deciduous broad-leaved small shrub (less than 1 m tall) narrowly distributed on lower mountain hillsides (altitude ca. 150-650 m above sea level). The species reproduces both sexually and vegetatively via rhizomes. Until recently it was included in its own genus, Echino...

“…A report claims that the southern boundary line of distribution needs to be extended further south because a large group of plants was recently found in Jiri Mountains (Longitude 127°27′-127°49′E, Latitude 35°13′-35°27′N) (Yakup.com). Before this discovery, it shows the characteristics naturally growing within the limited area in the north of Gangwon Province only (Sim et al 2006;Cheon et al 2009;Oh et al 2009). It is required to do research on proliferation and in situ and ex situ conservation systems, because of the high possibility of extinction caused by narrow spread of population and low number of individuals in every population.…”

To establish in vitro nodal culture conditions of Echinosophora koreensis Nakai, one of rare and endangered species famous for beautiful flowers in the Korean Peninsula, the influence of plant growth regulators (PGRs) on shooting and rooting from in vitro shoots was investigated. In shoot multiplication, addition of 6-benzylaminopurine (BA) to the half-strength Driver and Kuniyuki's media in the range of 2.22 to 8.88 μM induced 2.5 to 2.7 shoots per axillary bud; and addition of 2.27 μM thidiazuron (TDZ) produced 3.2 shoots, during 4 weeks of culture, while zeatin and isopentenyl adenine (2ip) were not effective on shoot multiplication as observed from several combination treatments of BA with other PGRs. Shoots established were smaller than 2 cm in length, in most of the treatments. while in BA 8.88 μM treatment more than 30% of shoots were longer than 2 cm and shorter than 4 cm. In rooting, naphthalene acetic acid (NAA) from 5.37 to 21.48 μM showed the rooting rate from 40.0 to 62.5%. Indole butyric acid (IBA) addition had little effect on rooting (＜10%), although some roots in IBA-containing media were longer than those in NAA. Micropropagation from axillary buds of nodular explants was applicable and promising to multiplication and conservation of Echinosophora koreensis Nakai.
