이 교수의 연구실은 식물의 대사 조절, 특히 항산화 물질인 플라보노이드, 이소플라보노이드, 폴리페놀 등 2차 대사산물의 생합성과 조절 메커니즘을 중심으로 연구를 진행하고 있습니다. 빛 조건, 유전자 변형, 환경 스트레스 등이 식물의 색소 형성과 생리적 기능에 미치는 영향을 분석하며, 식품 및 화장품 산업에 활용 가능한 기능성 식물 자원의 개발을 목표로 하고 있습니다. 특히 콩, 사질초, 사과, 편백나무 등 다양한 식물에서 대사체 분석과 유전자 발현 분석을 융합한 연구를 수행하고 있습니다.

The development of soybean with high antioxidant activities for use in the food and cosmetics industries is a target of breeding programs. In soybean, antioxidants are associated with seed color, although the metabolic basis for seed coloration remains incompletely understood. We selected six γ-ray-induced mutant lines that exhibited black, partially black, brown, partially brown, or yellowish-white pigmentation in the seed coat. Antioxidant activity and contents of anthocyanins, flavan-3-ols, a
Red and blue artificial light sources are commonly used as photosynthetic lighting in smart farm facilities, and they can affect the metabolisms of various primary and secondary metabolites. Although the soybean plant contains major flavonoids such as isoflavone and flavonol, using light factors to produce specific flavonoids from this plant remains difficult because the regulation of light-responded flavonoids is poorly understood. In this study, metabolic profiling of soybean seedlings in resp
Abstract: Phenolics in dry Artemisia princeps Pampanini, an herbal plant traditionally consumed as food ingredients in Korea was extracted, fractionated, and quantified as well as evaluated for its neuroprotection for PC‐12 cells. Whole extract had 5,852 mg gallic acid equivalents/100 g of total phenolics and 6,274 mg and 9,698 mg vitamin C equivalents/100 g of antioxidant capacities assayed by DPPH and ABTS radicals, respectively. The fraction extracted with n ‐butanol had the highest levels of
Artificial pigmentation of apple fruits has been intensely evaluated to generate less pigmented red apples, which are profitable because of the changes in fruit quality. In this study, we analyzed the diversity of flavonoids and the patterns of flavonoid metabolic gene expression under light irradiation with or without methyl jasmonate (MeJA) treatment in immature (S1) and color-turning (S2) staged 'Fuji' apples. Further, we assessed the metabolic regulation at the gene level between anthocyanin
ABSTRACT Evaluation of salt tolerance in herbaceous perennials was performed with mature potted plants under greenhouse conditions. Six herbaceous perennial species were evaluated for their tolerance to aqueous solutions of various sodium chloride (NaCl) concentrations over a 21 day period by measuring growth, water transpiration, and leaf nutrient content. Potential exists for utilization of these species in somewhat challenging saline environments along roadsides and in urban landscapes. Speci
