1) 独脚金内酯与植物信号分子karrikins是当前植物学领域的研究热点，它们在调控植物生长发育、植物与丛枝菌根真菌共生以及植物寄生中都具有关键作用。然而，独脚金内酯与karrikins调控这些生物学过程的机制仍有待于研究。研究组将以拟南芥和小麦为研究对象，结合遗传学、生物化学、分子生物学、多组学分析等手段，解析独脚金内酯与karrikins调控植物生长发育、共生和寄生的机制。
2) 小麦是我国第三大粮食作物，关系国家粮食安全。华北是我国小麦主产区，但长期以来水资源严重匮乏，干旱是制约该地区小麦生产的主要因素之一。然而，目前关于干旱如何影响小麦产量的机制还不清楚，研究组将采取新的策略深入挖掘和鉴定调控小麦干旱条件下高产、稳产的关键基因，进而培育优质抗旱小麦新品种，确保国家粮食安全。
