Salt tolerance in soybean [Glycine max (L.) Merr.] is controlled by major quantitative trait loci (QTL) or single gene(s). Among soybean germplasm, wild soybean plant introduction PI 483463 was reported to have a single dominant gene for salt tolerance. The objective of this study was to genetically map the QTL in a recombinant inbred line (RIL) population(More)
In this study, gamma rays were used to irradiate embryogenic calli induced from cotyledon explants of Panax ginseng Meyer. After the embryogenic calli were irradiated, they were transferred to adventitious roots using an induction medium; next, mutated adventitious root (MAR) lines with a high frequency of adventitious root formations were selected. Two MAR(More)
Ionizing radiation directly and indirectly affects gene expression within the plant genome. To access the antioxidant response of rice to different types of ionizing radiation, rice seeds were exposed to gamma-ray, cosmic-ray and ion beam radiation. Exposure to ionizing radiation dramatically decreased the shoot length in all plants but not the root length(More)
Increasing the amount of oleic acid in soybean oil would reduce the need for hydrogenation, a process that creates unhealthy trans fatty acids. A previous study mapped six oleic acid quantitative trait loci (QTLs) from N00-3350 (~550 g kg−1 oleic acid) on soybean chromosomes (Gm) 5, 17, 18, and 19, which corresponds to linkage groups (LG) A1, D2, G, and L,(More)
Ionizing radiation (IR) affects gene expression from plant genomes. To monitor the genome-wide transcriptional changes induced by three types of IR, we used the rice Affymetrix GeneChip microarray to identify genes that are up- or down-regulated by gamma rays (GAs), cosmic rays (CRs) and ion beams (IBs). The overall expression patterns in rice seedlings(More)
Asian soybean rust (ASR), caused by Phakopsora pachyrhizi Syd., has the potential to become a serious threat to soybean, Glycine max L. Merr., production in the USA. A novel rust resistance gene, Rpp?(Hyuuga), from the Japanese soybean cultivar Hyuuga has been identified and mapped to soybean chromosome 6 (Gm06). Our objectives were to fine-map the(More)
Plant physiological and biochemical processes are significantly affected by gamma irradiation stress. In addition, gamma-ray (GA) differentially affects gene expression across the whole genome. In this study, we identified radio marker genes (RMGs) responding only to GA stress compared with six abiotic stresses (chilling, cold, anoxia, heat, drought and(More)
The QTLs controlling alpha-linolenic acid concentration from wild soybean were mapped on nine soybean chromosomes with various phenotypic variations. New QTLs for alpha-linolenic acid were detected in wild soybean. Alpha-linolenic acid (ALA) is a polyunsaturated fatty acid desired in human and animal diets. Some wild soybean (Glycine soja) genotypes are(More)
About 171 Calanthe species have been reported worldwide. However, only four species and two natural hybrids are known to grow naturally in South Korea. Classification studies of Calanthe orchids using molecular markers have been relatively limited. Therefore, the objectives of this study are to analyze the genetic diversity and relationships of four(More)
In Korea, chrysanthemum is the second-most popular cutflower next to roses and can be divided into two main groups: spray and standard types according to their usage. The standard-type chrysanthemums are often used for condolence, and the important traits of this type include lack of branching and a long flowering period. This study was performed to compare(More)
