research areas
  • Research on the plant improvement technology based on plant omics (genome, transcriptome, metabolome, etc.)
  • Analysis on the function of useful genes and development of molecular marker
  • Research on the improvement of storage of sweet potato and metabolic engineering of antioxidant material of pigment
  • Development and research of original technology that produces plant-based bio rubber instead of petrochemistry
  • Cooperative research with China and Kazakhstan for global green technology cooperation based on plant
  • Decoding plant genome and making information resources
    • We participated in the Korea-China-Japan consortium to decode sweet potato genome (6X, 2.4Gb) completely and analyzed transcriptome for each part of sweet potato and at the environmental stress level. Based on the analysis we established information resources.
    • The major gene resource 41 system of cabbage was decoded, gene mutation was analyzed and basic genome map was established and standard genome sets were secured.
    • The standard genome information of native oriental melon was decoded and strawberry genome information was decoded and other genome information was secured to make a DB
  • Development of complex environmental stress tolerant plant and finding characteristics
    • Under the adjustment of oxidation stress induction SWPA2 promoter, AtNDPK2 gene, IbOrange gene induced transformation sweet potato, alfalfa and poplar were developed and inspected regarding tolerance to drying, high salinity and oxidation stress
  • Development of transformed sweet potato which has strengthened pigment antioxidant material
    • Transformed sweet potato culture cell which has high concent of ß-Carotene by deterring the expression of ß-Carotene hydroxylase (CHY-ß) or lycopene ε-cyclase (LCY-ε) was developed. In addition, IbOrange gene which involves in the accumulation of carotenoid was adopted to purple sweet potato to develop transformed sweet potato that accumulates both anthocyanin and carotenoid at the same time.
  • Development of natural rubber production technology from Russian dandelion
    • The genome of latex tissue of Russian dandelion was analyzed and natural rubber bio synthesis circuit gene groups were separated and identified
    • The microorganism that induces rubber content in Russian dandelion and chemical treatment technology was developed and application for patent was completed.
  • Development of chloroplast transformation technology
    • The cancer found that there are various types of extrachromosome within chloroplast and executed utilization technology research successfully.
  • Development of large-scale growth of herbal plants
    • The technology to grow microtuber in large scale from cell suspension culture based on herbal medicine was developed
  • Development of plant improvement technology and molecular marker
    • The backcross selection marker, breed purity verification marker, system fixation verification marker and functional material content verification marker, which enable shortening of breeding period of cabbage and precise breeding, were developed and applied to the field and molecular marker to differentiate kind of oriental melon was developed.
