MYB proteins are a superfamily of transcription factors (TF) that play regulatory roles in developmental processes and resistance mechanism in plants. We identified 130 and 109 genes in the MYB superfamily from an analysis of the complete Arabidopsis and rice genome sequence. Although microarray based transcriptome analysis approach allows the investigation of the biological networks of MYB TF in DNA level, the underling mechanisms related to their functional role is not fully understood. In this work, we performed meta-analysis of public microarray data that analyzed with Arabidopsis and rice using co-expression analysis. A phylogenetic comparison of the members of this superfamily were performed with Sorghum bicolour to suggested that MYB super family underwent a rapid expansion their evolutionary times. We identified conserved expression pairs which play important role in transcription. Our comprehensive analysis of this huge transcription factor of Arabidopsis and rice may shed further light on the possible biological roles of the MYB TF in various plants.

Achyrantes japonica (AJ) has been used to treat edema and arthritis in the traditional Korean medicine. Toelucidate the anti-inflammatory and anti-nociceptive effects of ethanol extract of AJ, the carrageenan-induced pawedema using a plethysmometer and thermal hypersensitivity using the plantar test were measured. Ibuprofen was used asa control drug. Treatment with AJ (200㎎/kg p.o.) significantly reduced paw edema, compared to the carrageenan -treated rats. In the plantar test, the thermal withdrawal latency in AJ - treated group was significantly increased than thecarrageenan - treated group. The results indicate that AJ could have be the anti-inflammatory and anti-nociceptive prop-erties.

Rapid extension of genomic database leads to the remarkable advance of functional genomics. This study proposes a novel methodology of functional analysis using 5-methyltrytophan (5 MT) mutant together with their 2-DE analysis and public microarray database. A total of 24 proteins was changed in 5 MT mutant and four remarkably different expressed proteins were identified. Among them, three spots were converted to Affymetrix probe. A total of 155 microarray samples from Gene Expression Omnibus (GEO) in NCBI was retrieved and followed by constructing gene co-expression networks over a broad range of biological issues through Self-Organising Tree Algorithm. Three co-expressing gene clusters were retrieved and each functional categorization with differential expression pattern was exhibited from 5 MT resistance mutant rice. It was indicated new co-expression networks in the mutant. This study suggests that on investigating possibility which correspond 2-DE to microarray database with their full potential.

A new standard rose cultivar 'White Christmas' was bred from the cross between red standard cultivar 'Red Queen' and pink standard cultivar 'Vivaldi' at the National Horticulture Research Institute. The cross was made in 2001 and `White Christmas' was finally selected in 2006 after investigating characteristics for three years from 2003 to 2006. 'White Christmas', a white standard cultivar grows vigorously and has good flower shape. The major characteristics of this cultivar are 123.8 stems/m2/year in yield, 82.3 cm in length of cut flower, 11.0 cm in flower diameter, 60.1 in petal number, and 12.2 days in vase life. This cultivar can be propagated by both cutting and grafting. The consumer's preference of this cultivar is relatively higher than that of control cultivar, 'Tineke'.

A new standard rose cultivar 'Magic Pink' was bred from the cross between light yellow standard cultivar 'Medeo' and pink standard cultivar 'Veronica' at the National Horticulture Research Institute. The cross was made in 2001 and 'Magic Pink' was finally selected in 2006 after investigating characteristics for three years from 2003 to 2006. 'Magic Pink', a pink standard cultivar grows vigorously and has fashionable flower color. The major characteristics of this cultivar are 184.8 stems/m2/year in yield, 63.0cm in length of cut flower, 7.2 cm in flower diameter, 28.5 in petal number, and 10.4 days in vase life. This cultivar can be propagated by both cutting and grafting. The consumer's preference of this cultivar is relatively higher than that of control cultivar, 'Noblesse'.

A new black seed coat soybean variety, “Socheong” was developed at the Yeongnam Agricultural Research Institute (YARI) in 2006. The goal to breed the black seed coat soybean is to develop the cultivar with high yield, lodging tolerance, resistant to disease such as soybean mosaic virus (SMV), and bacterial pustule and seed size. Socheong was selected from the cross between Milyang 78, which was late maturing, susceptible to lodging and SMV and with large seed size and green cotyledon, and Peking which was tolerant to lodging and with small seed size. The preliminary, advanced and regional yield trials for evaluation and selection of this variety were carried out from 2002 to 2006. It has determinate growth habit, white flower, brown pubescence, brown pod color, black seed coat, green cotyledon, elongated flattened seed shape, oval leaf shape and small seed size (15.7 grams per 100 seeds), and it was 3 days later in maturity than the check cultivar Cheongjakong. Socheong was higher, in the seed quality of sucrose and total sugar contents (6.8 and 8.2%) and isoflavone contents (1,754 ㎍/g) than the check cultivar. Futhermore, it has good characteristics for mechanical harvest, such as lodging tolerance, pod shattering and stem diameter. It also has been identified to have resistance to soybean mosaic virus symptom which was the troublesome soybean diseases. The average yield of Socheong was 2.21 ton per hectare in the regional yield trials carried out in four locations of Korea among seven locations from 2004 to 2006, which was 5 percent lower than the check cultivar Cheongjakong.

A new black seed coat soybean cultivar, “Heugmi” was developed at the Yeongnam Agricultural Research Institute (YARI) in 2006. The goal to breed the black seed coat soybean is to develop the cultivar with high yield, lodging tolerance, resistant to disease such as soybean mosaic virus (SMV), and bacterial pustule and seed size. Heugmi was selected from the cross between Milyang 78, which was late maturing, susceptible to lodging and SMV and with large seed size and green cotyledon, and Milyang 68, which was middle maturing, resistant to lodging and SMV and with middle seed size and yellow cotyledon. The preliminary, advanced and regional yield trials for evaluation and selection of this cultivar were carried out from 2001 to 2006. It has determinate growth habit, purple flower, brown pubescence, black pod color, black seed coat, green cotyledon, spherical seed shape, oval leaf shape and middle seed size (24.8 grams per 100 seeds), and it was 2 days earlier in maturity than the check cultivar Cheongjakong. Heugmi was better in the seed quality of crude protein contents, sucrose and total sugar contents than the check cultivar. It also has been identified to have resistance to SMV which was the troublesome soybean diseases. The average yield of Heugmi was 2.53 ton per hectare in the regional yield trials carried out in seven locations of Korea from 2004 to 2006, which was 8 percent higher than the check cultivar Cheongjakong.

The genetic diversity was evaluated using RAPD and ISSR among natural populations and Korean wheat cultivars (Triticum aestivum). Understanding the genetic diversity of putative parental and wild stocks would be useful in wheat breeding programs. Ninety three populations were evaluated with fifty RAPD and three ISSR primers. A total of 185 RAPD and ISSR polymorphism were produced. These markers were considered to estimate the genetic distance among accessions. The genetic similarity ranged from 0.41 to 0.86. The dendrogram were constructed by using the UPGMA clustering algorithm based on genetic similarity. The genetic diversity within and among accession was assessed through Principal Component Analysis (PCA) for statistics analysis. In cluster analysis, four groups were clustered and 17 accessions were not clustered. The PCA was corresponded well to the result. This study provides basic information about the genetic relationships for breeding purposes.
