“…Random amplified polymorphic DNA (RAPD) is a useful method to determine several genetic parameters of rare and endangered plants, as it requires low amounts of plant tissue (Trindade et al, 2012) and obtains DNA fingerprints without accessing genome sequence information (Liu et al, 2012;Rodrigues et al, 2013). Despite its vulnerable status and scattered distribution, no investigation has been undertaken on G. microrrhynchum using molecular markers, except for the study by Chang et al (2005) using allozymes. In the present study, we used RAPD to evaluate the genetic variation within and among populations of G. microrrhynchum.…”

“…(Berberidaceae) is a perennial herb that is distributed throughout Manchuria, Northeast China, and the Korean Peninsula, where it is restricted to the high-altitude Baekdudaegan [about 1000 m above mean sea level (AMSL)] mountain range, which constitutes the species' southern limit (Lee et al, 2011). G. microrrhynchum is facing a high risk of extinction because of its small number of regional groups and habitat destruction and fragmentation (Chang et al, 2005). It is designated a rare plant by the Korean Forest Service and rated as vulnerable in the Rare Plants in Korea Data Book because of concerns about habitat destruction caused by climate change (Chang et al, 2005;Korean National Arboretum, 2012).…”

Conservation implications of the genetic diversity of Gymnospermium microrrhynchum in Korea

ABSTRACT. Gymnospermium microrrhynchum (Berberidaceae) is an ephemeral perennial herb with a limited distributional range in the Baekdudaegan mountain areas of the Korean Peninsula, and is designated a rare plant by the Korean Forest Service. Information about its genetic variation and structure is important for developing successful conservation strategies. To investigate the genetic variation within and among seven G. microrrhynchum populations, random amplified polymorphic DNA data were obtained for 207 individuals. The populations exhibited relatively low genetic diversity: the percentage of polymorphic bands (PPB) ranged from 32.1 to 66.7% (mean = 51.4%) and Nei's gene diversity (H E ) ranged from 0.116 to 0.248 (mean = 0.188). However, genetic diversity at the species level was relatively high (PPB = 98.7%, H E = 0.349). An analysis of molecular variance revealed high differentiation among populations (F ST = 0.6818), but the low gene flow value (N m = 0.117) suggests a low level of gene exchange occurs among populations. Principal coordinates analysis revealed that individuals were separated according to population. The high level of genetic differentiation and restricted gene flow among G. microrrhynchum populations, which resulted from their isolation in alpine areas after the Ice Age, indicates that it is essential to protect and manage all populations, rather than focus on specific populations, in order to maintain the genetic diversity of this species.

“…In general, population size and within-population genetic diversity shows a positive relationship (Chang et al, 2005;Frankham et al, 2002), however, population PS showed high genetic diversity although it has a small population size. On the other hand, population IG showed high genetic diversity with the largest population size.…”

Abstract. Paliurus ramosissimus (Rhamnaceae) is a deciduous shrub found on the seashore of Jeju Island, located at the southern tip of the Korean peninsula, and has been designated a rare plant species by the Korea Forest Service. Random amplified polymorphic DNA was used to investigate the genetic variation within and among P. ramosissimus populations on Jeju Island. Populations of P. ramosissimus showed a relatively low genetic diversity. The percentage of polymorphic bands (PPB) ranged from 33.3% to 63.6% (average = 51.4%), Shannon's information index (I) ranged from 0.213 to 0.352 (average = 0.316), and Nei's gene diversity (H) ranged from 0.149 to 0.239 (average = 0.218). Analysis of molecular variance and Nei's gene differentiation coefficient showed low genetic differentiation among populations (Φst = 0.207 and Gst = 0.186). The level of gene flow was sufficient to counter population divergence due to genetic drift (Nm = 0.109). Population genetic information obtained from this study could provide a valuable baseline for conservation and management plans for this species; P. ramosissimus on Jeju Island have to be protected through in situ conservation. The populations Pyo-sun and Il-gwua with high genetic diversity have conservation priority. In particular, Pyo-sun population protection must be the highest priority, as this population was revealed to have a high genetic diversity despite its small size.

“…Populations of this species ranging in size from 100 to 1,200 individuals are distributed patchily. The species was classified as "Regionally Vulnerable" on the recent proposition for the Korea Red List of vascular plants (Chang et al, 2001). This herbaceous perennial consists of rosette with its radical leaves arising from single deep root on open bare rocks and has 10-40 small green umbels.…”
