种子生物学研究组成立于2019年11月，隶属于中国科学院西双版纳热带植物园热带植物资源可持续利用重点实验室。课题组依托云南丰富的植物种质资源，围绕我国热带、亚热带重要植物资源特别是稀有濒危植物种质资源的保育需要，利用分子生物学、遗传学、生物信息学及生物化学等学科知识与实验技术，开展种子生物学遗传基础及应用研究，挖掘并鉴定控制植物种子发育、休眠、萌发、储藏、营养品质及顽拗性形成相关重要功能基因或信号通路，从而为重要经济植物和典型热带植物保育提供重要知识和技术基础。
主要研究方向为：
(1)以水/陆稻和拟南芥为研究对象，通过正向遗传学及反向遗传学原理揭示植物种子发育、休眠、萌发、储藏、营养品质及其适应极端环境的分子机理及信号传导网络，为作物分子育种提供技术和理论指导。
(2)以热带植物为研究对象，开展热带植物种子顽拗性形成的分子机理研究，揭示顽拗性形成的内在原因，阐明顽拗型种子贮藏特性的分化、遗传和分子机制，为顽拗型种子的贮藏及长期保存提供理论依据。
Seed biology Group, affiliated to the Key Laboratory of Tropical Plant Resources and Sustainable Use of Xishuangbanna Tropical Botanical Garden (XTBG), Chinese Academy of Sciences, was set up in November 2019. Relying on the rich plant germplasm resources in Yunnan and the urgent conservation needs for the rare and endangered species in both tropical and subtropical regions, we use the discipline knowledge and experimental technologies associated with plant molecular biology, genetics, bioinformatics and biochemistry to carry out both fundamental and applied studies around specific scientific issues concerning seed biology.
The specific research fields are listed below:
(1) Using paddy/upland rice and Arabidopsis thaliana as research materials, decipher the regulatory mechanism and signaling network controlling seed development、dormancy、germination、storage and nutritional quality, and also decipher the regulatory mechanism of seeds upon diverse adversities such as cold, heat, drought and salinity;
(2) Using tropical plants as research materials, dig the key genes and decipher the regulatory mechanism and signaling network that control seed recalcitrance, and explore effective technologies that contributes to the preservation of tropical recalcitrant seeds.
