Rhim, Tae-Jin ;
Korean Journal of Plant Resources, volume 26, issue 2, 2013, Pages 149~158
DOI : 10.7732/kjpr.2013.26.2.149
The objective of this study was to investigate the antioxidative capacity of ethanol extracts from Sanguisorbae officinalis L. root (Sanguisorbae radix) in vitro. The concentration of Sanguisorbae radix extract at which DPPH radical scavenging activity was inhibited by 50% was 0.33 mg/mL, which was similar to
-tocopherol (0.40 mg/mL), as compared to 100% by pyrogallol as a reference. Total antioxidant status was examined by total antioxidant capacity against ABTS radical reactions. Total antioxidant capacities of Sanguisorbae radix extract were significantly (p<0.05) higher than those of
-tocopherol. Superoxide scavenging activities of Sanguisorbae radix extract were significantly (p<0.05) higher than those of catechin. Oxygen radical absorbance capacities of Sanguisorbae radix extract were significantly (p<0.05) higher than those of ascorbic acid. Cupric reducing antioxidant capacities of Sanguisorbae radix extract were significantly (p<0.05) higher than those of
-tocopherol. Sanguisorbae radix extract prevented supercoiled DNA strand breakage induced by hydroxyl radical and peroxyl radical. Total phenolic contents of Sanguisorbae radix extract at concentrations of 0.5 and 5 mg/mL were 0.50 and 3.33 mM gallic acid equivalents, respectively. Sanguisorbae radix extract at concentration of 0.01, 0.1 and 0.5 mg/mL inhibited 0.2 mM tert-butyl hydroperoxide-induced cytotoxicity by 33.8, 79.1 and 96.9%, respectively, in HepG2 cell culture system. Thus, strong antioxidant and cytotoxicity-ihnibiting effects of Sanguisorbae radix extract seem to be due to, at least in part, the prevention from free radicals-induced oxidation as well as high levels in total phenolic contents.

DOI : 10.7732/kjpr.2013.26.2.159
The study was conducted to determine the content of phenolics and flavonoids, antioxidant activity and antioxidant enzyme activity for the extract from 7 days old sprouts of cowpea (cv. "Seowon"), mungbean (cv. "Owool") and soybean (cv. "Pungsannamulkong"). Sprout length and weight of soybean sprouts were higher than those of cowpea and mungbean sprouts. Total phenolics content [mg ferulic acid equivalents (FAE)
DW] was highest in soybean sprout extracts (82.2 mg
), followed by cowpea (32.2 mg
) and mungbean (24.5 mg
) sprout extracts (p < 0.05). The result of total flavonoid level [mg rutin equivalents
DW] had same tendency to the total phenolics, showing lower amounts. The antioxidant activity of the methanol extracts from all the plant dose-dependently increased. DPPH (1,1-diphenyl-2-picryl hydrazyl radical) free radical scavenging activity was higher in cowpea (44%) and mungbean (42%) sprouts than in soybean sprouts (25%). Among antioxidant enzymes, APX and POX activities were highest in cowpea sprouts and CAT and SOD activities in soybean sprouts. The results showed that total phenolics content (
= 0.5320 ~ 0.9032) and total flavonoids level (
= 0.4672 ~ 0.9380) were highly correlated with antioxidant or with antioxidant enzyme activity, and that the level and activity of biologically active substances were different depending on plant species.

DOI : 10.7732/kjpr.2013.26.2.169
We investigated the effect of extracts(
) from 31 folk plants in Ulleung Island on nitric oxide(NO) production in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. Actinidia arguta(leaf, twig), Hovenia dulcis(leaf), Camellia japonica(leaf, twig), Sambucus sieboldiana var. pendula(leaf, twig) and Fallopia sachalinensis(root) showed significant NO inhibition activity(42%~88% NO inhibition rate). Of them, we selected 3 samples(A. arguta, H. dulcis and C. japonica) showing more than 50% NO inhibition activity and little effect on cell viability. We found that the extracts suppressed the NO and prostaglandin
produced by LPS-activated RAW264.7 cells in dose-dependent manners.

DOI : 10.7732/kjpr.2013.26.2.271
Morphology of Korean Scrophularia species were reviewed to clarify taxonomic characters, their variations and taxon delimitation. Habitats, root forms, foliaceous types, glandular trichomes on stems and leaves, flowering seasons, calyx shapes, corolla colors and shapes, as well as ovary basal shapes are diagnostic characters to classify series in this genus. From the result, 1) S. alata is distinguished from its closely related species S. takesimensis by lengths of stem ribs, widths of petioles, and types of corolla lobes; 2) S. buergeriana is characterized by spike-like inflorescences, short peduncles and pedicels, and yellowish green corollas; 3) lanceolate-shaped leaves and calyces, and axillary-like cyme inflorescences delimitate S. koraiensis easily from the other taxa; 4) smaller leaves discriminate S. kakudensis var. microphylla from S. kakudensis var. kakudensis, and 5) S. cephalantha is distinguished from S. kakudensis by broadly ovate to sub-orbicular shaped leaves, earlier flowering seasons, and smaller numbered flowers on shorter inflorescences. In conclusion, the Korean Scrophularia is classified as 7 taxa, 6 species and 1 variety in 2 series. Keys to the series and taxa are provided.

Kwon, Soo Jeong ; Cho, Kab Yeon ; Kim, Hag Hyun ;
Korean Journal of Plant Resources, volume 26, issue 2, 2013, Pages 284~288
DOI : 10.7732/kjpr.2013.26.2.284
This study aimed to get the basic data on the breeding of good varieties in Hypericum patulum Thunberg. The optimum materials, concentration and soaking time were examined to identify the effective approach to induce tetraploid plant by colchicine treatment to cultivate the varieties. For the seed germination rate of seed by colchicine treatment, the higher colchicine concentration was and the longer soaking time was, the more the germination rate decreased. While individuals were germinated in 16 test groups except control group (no treatment group), all the plants were diploid and no tetraploid was induced. For the plant regeneration rate by colchicine treatment on the explant of Hypericum patulum Thunberg that was under in vitro culture, the higher the colchicine concentration increased, the ress the regeneration rate. While total 147 individuals were regenerated in all treatment, when the explant was soaking treatment in more than 0.05% for over 6 hours, tetraploid could be obtained. In the soaking treatment of 0.05% for over 6 hours, tetraploid could be obtained. In particular, for the soaking treatment in 0.05% for 12 hours, 8 tetraploids were induced, which was about 47.1% of the number of plant regenerated. In accordance with the observation on doubling of DNA contents in leaf in order to identify polyploidy, the peak DNA content of G1 phase was 94.5 for diploid and 192.5 for tetraploid. It confirmed doubling of DNA content. Furthermore, the number of chloroplasts per guard cell depending on polyploid was around 10 in diploid and 17 to 19 in tetraploid, which were around 1.7 to 1.9 times as much as diploid.

DOI : 10.7732/kjpr.2013.26.2.289
Surveys were conducted to study nationwide distribution and identify habitats and host plants of Cuscuta pentagona Engelm. as a parasite. The major habitat types were arable land near agricultural waterways (54.3%), open field near roadside (41.3%) and artificial grassland (4.3%). The investigated host plants of Cuscuta pentagona consist of total 130 taxa: 10 varieties, 1 subspecies, 119 species, 95 genera, and 37 families. Among them, 30 taxa were alien plants. As for the useful plants, there were 59 taxa of edible ones (45.4%), 54 taxa of medicinal ones (41.5%), 13 taxa of ornamental ones (10%), 13 taxa of industrial ones (10%), and 9 taxa of pasture ones (6.9%). On arable land, it caused damage particularly to the growth of agricultural crops such as Oryza sativa L. (Rice) and fruits such as Malus pumila Mill. (Apple) etc. Its growth and distribution may cause economic loss for crops because of the close location of the arable land.

Korean Journal of Plant Resources, volume 26, issue 2, 2013, Pages 303~309
DOI : 10.7732/kjpr.2013.26.2.303
This study was performed to clarify the effect of medium compositions and plant growth regulators on the shoot, root formation and growth of 'Jarang' grape for mass propagation of virus-free plant. The formation and growth of shoot were considerably favorable in half-concentration of MS medium. However, the formation of adventitious root per explants (avg. 2.1) was effective in higher concentration (two times) of MS medium. For sucrose concentration, 1% for the shoot formation, 3% for the adventitious root formation and 1% for the growth were observed as yield significant results. With the addition of 0.05% of activated carbon, the shoot growth was improved, and it was effective for the adventitious root formation and growth as well. A pH of 6.8 in the medium was the most suitable for mass propagation; the results showed significant enhancement in the number of nodes and the length of the shoot, 3.9 and 1.3 cm, respectively. The shoot growth was the most vigorous in BA 1.0 mg/L due to the impact of the growth regulator on the mass propagation in it. Consequently, 16.9 shoots per explant were formed in NAA 1.0 mg/L so good results were obtained.

DOI : 10.7732/kjpr.2013.26.2.310
The genetic diversity and structure of eight populations of Coreanomecon hylomeconoides Nakai, an endemic Korean plant, were investigated using 50 ISSR loci from eight primers. The average percentage of polymorphic loci was 47.3%. The Shannon's index (SI=0.218) and gene diversity (h=0.142) were relatively lower than those of other long-lived perennials. The Sancheong (SI=0.233, h=0153), Gwangyang (SI=0.263, h=0.171), and Suncheon (SI=0.241, h=0.159) populations showed greater genetic diversity than the Namhae and Gwangju populations, which are on the edge of the distribution. Analysis of molecular variance (AMOVA) showed that 18% of the total variation could be attributed to differences among populations, and 82% to differences within populations, indicating moderate gene flow among adjacent populations. These results were supported by value of Nm (2.184). The UPGMA conducted using the genetic distance and Bayesian cluster analysis showed a remarkable geographic trend structured into east and west regions. Overall, the results indicate that the Sancheong and Gwangyang populations, which had a large population size and higher degree of genetic diversity, should be the focus of in situ conservation.

Ryu, Jaihyunk ; Kim, En-Hwan ; So, Hyun-Su ; Chung, Mi-Young ; Song, Won-Seob ; Bae, Chang-Hyu ;
Korean Journal of Plant Resources, volume 26, issue 2, 2013, Pages 320~327
DOI : 10.7732/kjpr.2013.26.2.320
This study was carried out to address an efficient in vitro regeneration system from seed-derived callus of Phragmites communis, and to evaluate genetic variations of the regenerants using ISSR markers. Shoot regeneration via calli was greatly influenced by N6 medium compared with MS medium, and plant regeneration frequency was 90% in N6 supplemented with BA 0.25 mg/L and BA 0.5 mg/L. According to ISSR analysis of the thirty regenerants, out of 94 loci detected overall, 16 were identified to be polymorphic with a rate (PR) of 17.0%. The mean gene diversity (h) of different in vitro condition was 0.03 and ranged from 0.008 for N6 with BA 5 mg/L, to 0.040 for MS with IAA 0.1 mg/L+kinetin 2 mg/L. The results indicate that the regenerants have a low genetic variation, and ISSR analysis is effective to detect genetic variation of regenerants.

The National Agrobiodiversity Center is the nodal agency assigned as the National Agricultural Genebank of the Rural Development Administration. Its main role is to collect, conserve, evaluate and distribute plant genetic resources. As of 2010, NAC has distributed a total of 380,981 accessions in the last 20 years (1991-2010) or an average of about 19,000 accessions per year. To meet customers' demands for germplasm and derive quality improvements, a mail survey in 2011 was conducted among the genetic resource users in 2010. Most of the clients obtained information on the germplasm conserved in the national genebank from the NAC website or NAC staff, and they sought specific traits in the samples. Most users received the materials within 15 days, and wanted useful data together with genetic resource. Korean landrace was the most frequently requested accessions. According to the survey results, it is supposed that useful genetic resources should be preferentially collected and their characterization/evaluation should be strengthened to enhance the utilization of genetic resources.
