研究领域（Research Area）
Light is the most important environmental cue for plant growth and development.To cope with the changing light environments, plants have evolved the capacity to optimize their growth.Since 1970s, an increase in UV-B irradiation has occurred due to ozone depletion. From the historical point of view, UV-B light is regarded as a damaging stimulus to plants. Yet, currently advanced scientificinvestigation has revealed that plants benefit from UV-B irradiation in terms of photomorphogenicdevelopment, secondary metabolism, photoprotection, antioxidative response and resistance to pest anddisease attack. Beyond the area of plant researches, UV-B photobiology has advanced the tool development that allowsthe optical control of spatiotemporal signaling events in mammalian cells. These facts raise the possibilities that UV-B-mediated responses can be exploited to facilitate sustainable crop production, environmental conservation, and protein engineering in medical applications. Our lab aims to elucidate the molecular andbiochemical mechanisms of the UV-B light-mediated plant development. Combinatory approaches ofbiochemistry, molecular genetics, cell biology and computer science will be applied to investigate molecularframework of UV-B signaling cascade and crosstalk between UV-B light signal and other environmentalsignal pathways.
光是影响动植物生命活动最重要的环境因子。上世纪70年代以来，臭氧层空洞导致UV-B辐射增强，对自然环境与人类活动带来深远影响。最新研究发现，UV-B光在光形态建成、次级代谢、抗病虫害等方面有益于植物发育。同时，UV-B光遗传学工具可用于动植物细胞中的信号转导调控。针对UV-B光能源研究与利用的不足，本课题组综合利用生物化学、分子生物学、遗传学、细胞生物学、数学、信息学等交叉学科手段，探索UV-B光调控的植物生长发育，及其与其它环境信号的整合，对光能源在环境与农业中的科学应用具有重大的指导意义。
