히로야수 야마구치 교수의 연구실은 주로 고분자 및 분자 인식을 기반으로 한 자가조립 시스템을 연구하며, 특히 아조벤젠 유도체와 시클로덱스트린 간의 광반응성 상호작용을 활용한 광조절형 젤 재료 개발에 초점을 맞추고 있습니다. 또한 식물의 돌연변이 육종을 위한 이온 비임의 기술과 방사선 조사 조건이 식물의 유전자 및 형질에 미치는 영향에 대해서도 심층적인 연구를 수행하고 있습니다. 이는 나노소재 개발과 식물 유전자 변형 기술의 융합적 응용을 목표로 하고 있습니다.

The formation of effective and precise linkages in bottom-up or top-down processes is important for the development of self-assembled materials. Self-assembly through molecular recognition events is a powerful tool for producing functionalized materials. Photoresponsive molecular recognition systems can permit the creation of photoregulated self-assembled macroscopic objects. Here we demonstrate that macroscopic gel assembly can be highly regulated through photoisomerization of an azobenzene moi
We investigated the usefulness of ion beams for mutation breeding in rice (Oryza sativa L.) by comparing the efficiency (i.e., the ratio of desirable mutations to plant damage such as lethality and sterility), mutation rate, spectrum, and optimum dose to that of gamma rays. Rice seeds were irradiated with carbon ions (mean linear energy transfer = 76 and 107 keV/μm), helium ions (9 keV/μm), and gamma rays, and their survival and fertility were examined in the M1 generation. The frequency of chlo
We investigated the effect of total irradiation dose and dose rate on flower color mutation and nuclear DNA content as an index of radiation damage in chrysanthemum. Chrysanthemum morifolium cv. ‘Taihei’ plants grown by in vitro culture were gamma-irradiated with a total dose of 15, 30 and 60 Gy at a rate of 0.5, 1, 2 and 5 Gy/h. Leaf explants cut from the irradiated plants were tissue cultured, and the regeneration rates and frequency of flower color mutation were investigated. Nuclear DNA cont

Ornamental plants that have a rich variety of flower colors and shapes are highly prized in the commercial flower market, and therefore, mutant cultivars that produce different types of flowers while retaining their growth habits are in demand. Furthermore, mutation breeding is well suited for ornamental plants because many species can be easily vegetatively propagated, facilitating the production of spontaneous and induced mutants. The use of ion beams in mutation breeding has rapidly expanded
