课题组简介：

本课题组是“浙江省药用植物种质改良与质量控制技术重点实验室”等省市平台的核心团队，主要从事药用植物疗效品质形成的环境调控机制等方面的研究工作。近年来，重点以杭白菊、银杏、长春花等为材料解析紫外光（UV-B）等逆境因子诱导活性组分积累的分子机制，旨在阐明逆境胁迫促进药用植物品质形成（优质药材道地性形成）的信号转导机制，并以此为基础研制开发促进药用植物活性组分积累的新型分子逆境仿生调控技术，为解决制约优质药材生产的瓶颈问题、推动产业创新升级提供技术支撑。同时开展杭白菊、银杏、长春花等药用植物活性组分生物合成途径解析及枇杷等果蔬保鲜新技术等研究工作。

课题组成员主持研究国家自然科学基金项目9项、其它省部级项目十余项。揭示了CmUVR8等信号通路在介导UV-B等逆境因子诱导药用植物活性组分合成中的作用，解析了以MT等为关键节点调控逆境胁迫促进杭白菊活性组分积累的信号机制，建立以PC-410为靶点在不依赖逆境的情况下促进药用植物疗效品质形成的分子逆境仿生调控新技术，在药用植物资源学研究领域形成了明显的特色和优势。研究成果获得浙江省科技进步奖和省高校科技成果一等奖。在“Industrial Crops and Products”、 “Plant Cell & Environment”、 “Plant Physiology”以及“中国科学”等国内外本学科主流刊物发表相关研究论文70余篇。
