学科组简介
本学科组是我国率先从事陆生藻类、生物土壤结皮和空间生物学研究的科研团队，主要以荒漠、盐碱地、临近空间等特殊环境中的藻类为研究对象，研究它们的多样性、生理代谢、适应进化、空间生态生命支持系统构建、经济产物等方面的特征及形成机理。已建立测定藻类固沙能力的标准方法，开辟利用藻类进行退化土壤生态系统综合治理的新技术；构建的空间生命支持系统在近地轨道实现了20多天稳定运行，并执行了十多次的中外空间飞行计划。目前承担的科研任务主要有国家重点研发计划、国际合作专项、中国科学院战略性先导科技专项(A类)、国家载人航天工程项目、国家自然科学基金等。相关成果已获国家授权发明专利数11项，省部级自然科学二等奖1项，科技进步三等奖2项。发表科研论文两百多篇(SCI源刊160多)，参编专著3部。
研究方向有：
1) 运用高通量测序、多组学等大数据手段，跨极干旱、干旱、半干旱到半湿润多个气候带，从群落组成、装配，藻类生长代谢、环境互作等方面研究自然生物结皮及人工诱导蓝藻结皮的生态环境效益及作用机理，以推动接种蓝藻的生态修复技术的革新。
2) 将分子生态学实验手段(高通量扩增子、比较基因组和转录组)与生物统计学方法相结合，综合评估环境胁迫条件下蓝藻细胞生理、分子调控与群落多样性及种间相作响应网络, 以期深入认识陆生蓝藻多样性及其维持生态系统功能的潜在机制。
3) 从微藻的碳固定、转化途径、高附加值产物积累、碳流分配调控等层面研究微藻在减排和经济利用方面的潜能。
4) 利用高通量测序、生物信息学、分子生物学等技术，研究藻类在多种胁迫(高温、高盐、强辐射等)下，信号传导和表观遗传方面的响应机制。
5) 以微藻、原生动物、鱼类、维管植物等构建不同封闭系统，研究各成员适应空间飞行环境的生长代谢和互作关系，及封闭系统的生态功能和稳定性，以期为宇航员提供氧气、食物等生态生保系统。
