Aphids are generally considered as a major pest of corn. Thus, yield losses due to aphid infection can be considerable. Rhopalosiphum padi - the birdcherry oct aphid seems to be prevalent aphid species on maize in Korea. Aphid resistance of 91 Fls was assessed at two locations in Korea. In studies of combining ability for aphid resistance to different locations, GCA mean square was 4.48 times grater than that of SCA mean square. Thus, additive gene action was more important than that of non-additive gene action to aphid resistance. In two locations, inbreds 2, 4, 5 and 10 had negative GCA effects for aphid resistance.

In order to uncover gene regulatory networks clustering of co-expressing genes was performed using a rice micorarray dataset of 155 gene expression omnibus sample (GSM) plates in NCBI, generating a total of 1660 clusters. One cluster with 85 co-expressing genes was measured with the correlation coefficient between pairs, resulting in an average r value of 0.66 with a range of -0.08 to 0.98. This result might support the notion that genes included in each cluster play common functional role(s). We also retrieved 23 Affymetrix GeneChip spots IDs corresponding to each of candidate genes related to abiotic stresses obtained from the P1antQTL-GE database and subsequently detected 23 clusters including co-expressing genes with each of the genes. Expression profiles of co-expressing genes revealed some degree of tissue-specific expression patterns, probably reflecting the existence of, at least partial, parallel versions of stress-related networks with evolutionary process, such as subfuntionalization. The finding that several cis-elements related to abiotic stresses was detected by differences in frequency between co-expressing genes and randomly selected genes. Clustering, expression profiles, and putative cis-acting regulatory elements of co-expressing genes related to abiotic stresses may provide clues to shed further light on the gene regulatory network of stress-responsive pathway.

dlm mutants controlling disease lesion mimic leaf trait may be useful in basic research of disease hypersensitive response and programmed cell death in soybean. The study on genetic relationship between dlm trait and other morphological C trait, position of dlm allele on classical linkage group, and a molecular marker linked to dlm allele was little reported. Two populations [T173 (ffDlmDlm) x T363 (FFdlmdlm), T363 (dlmdlmY9Y9) x T135 (DlmDlmy9y9)] were made to find independent assortment or linkage between dlm locus and f locus or between dlm locus and y9 locus. The segregation ratios of 3 : 1 were observed in the F2 population and the Chi-square values suggested that the disease lesion mimic leaf, fasciation stem, and chlorophyll-deficient leaf traits were controlled by a single recessive gene. Segregation ratios of 78 Dlm_F_: 19 Dlm_ff: 17 dlmdlmF_ : 3 dlmdlmff based on F2 phenotype showed that dlm allele was inherited independently with the f allele controlling fasciation stem trait in soybean. Also, segregation ratios of from 149 Dlm_Y9_: 41 Dlm_y9y9: 38 dlmdlmY9_ : 5 dlmdlmy9y9 based on F2 phenotype confirmed that dlm allele was inherited independently with the y9 allele controlling chlorophyll- deficient leaf trait in soybean. From these results, dlm allele would not be located on linkage group 11 (molecular linkage group: D1b+W) and linkage group 14 (molecular linkage group: E) in soybean. This results will helpful to attempt to position the Dlm locus on the soybean molecular linkage map.

An indica rice cultivar, Milyang23 is a semidwarf plant type with long and slender grains, whereas a temperate japonica rice cultivar, Stejaree45 is a japonica cultivar with short and bold grains. Genetic analysis was carried out to determine the number of quantitative trait loci (QTL), chromosome location, gene action, and effects of QTLS controlling grain length, width, thickness, and shape. The grain traits averages in the recombinant inbred lines (RILs) were near the mid-parent value, but the standard deviations in the RILs were more than those of the parents. A linkage map based on 138 simple sequence repeat (SSR) markers from 12 linkage groups was constructed using the 143 RILs as the base population. The map, spanning 1208 cM of the rice genome with an average interval length of 12.9 cM, was used for QTL analysis. A total of 13 QTLS for grain quality traits were identified. The phenotypic variation accounted for by each QTL ranged from 4.2% to 10.4%, with an average of 6.7%. Among the 13 QTLS, only one QTL accounted for more than 10% of the total phenotypic variation. Each of the traits studied was governed by one or two major QTLs that accounted for the large proportion of the total phenotypic variation. Several minor QTLS explain a small proportion of the total phenotypic variance.

The effects of the transferred green rice leafhopper (GRH) resistant gene on yield and grain quality were analyzed by using 7 near-isogenic lines (NILs) with introgressed GRH resistance gene in rice cultivar "Ilpumbyeo". The genotype analysis using SSR markers indicated that all NILs were recovered more than 95% as compared with recurrent parent "Ilpumbyeo". All NILs showed no significant differences compared to recurrent parent for grain yield. No significant differences were observed between NILs and their recurrent parent for physicochemical traits (protein content, amylose content and alkali spreading value) and eating quality. But there were significant differences for appearance of brown and milled rice and pasting properties between some NILs and their recurrent parent. It means that these grain appearance and pasting traits of NILs were very similar or more improved compared to recurrent parent "Ilpumbyeo". Thus, it could be possible to develop GRH resistant variety with high ,quality in segregating populations.

Genetic diversity and relationship among the accessions of cultivated types of Perilla frutescens and their weedy types were studied with 11 microsatellite markers. A total of 101 alleles were detected with an average allele number of 9.2 per locus among 70 Perilla accessions. Number of alleles per locus ranged from two for KWPE-39 to 21 for KWPE-53 and gene diversity for each locus was varied from 0.479 to 0.918 with an average of 0.715. The average gene diversity value was 0.626, 0.657, 0.509 and 0.524 for cultivated and weedy types of var. frutescens, and cultivated and weedy types of var. crispa, respectively. The weedy type accessions of var. frutescens and var. crispa showed more variation than corresponding cultivated type accessions. As for the cultivated type of var. frutescens, the accessions from China showed higher microsatellite diversity than those of Korea and Japan. An UPGMA phylogenetic tree revealed three major groups which were congruent with their morphological characters and geographical distribution patterns except for a few odd accessions. Although the wild ancestral species of cultivated types of P. frutescens has not yet been identified, our results may provide some evidence for the origin and the diffusion route of cultivated type of var. frutescens in East Asia. Cultivated Perilla crop might be originated in China, and its diffusion might be from China to Japan via Korea and the weedy types of Perilla crop are the key taxon in understanding the origin of cultivated type of both var. frutescens and of var. crispa.

This cultivar has a determinate growth habit, white flower, grayish brown pubescence, yellow seed coat, yellow hilum, lanceolate leaflet shape and small seed size (10.9 grams per 100 seeds). The maturity date of "Pungwon" is seven days earlier than that of the check variety, "Pungsan". It has a good seed quality for soybean-sprout. The soybean-sprouts grown from "Pungwon" have high isoflavone (5,935 μg/g) and amino acid (160 mg/g) contents. This cultivar has resistance to soybean mosaic virus (SMV), necrotic symptom (SMV-N), and other most troublesome soybean diseases which are bacterial pustule and black root rot. Especially, "Pungwon" has useful characteristics, such as lodging and shattering resistance. The average yield of "Pungwon" was 3.04 ton per hectare, about 7 % higher than the check variety, "Pungsan" at the regional yield trials (RYT) for double cropping.
