摘　　要：Tea(Camellia sinensis[L.]O.Kuntze.)is an important cash crop,which mainly uses tender shoots and young leaves for manufacturing.Due to the marketing characteristic that earlier made tea has higher price,the time of the breaking of winter dormancy buds in spring is extremely important in tea industry.Strigolactones are a group of carotenoids-derived metabolites which regulates bud outgrowth,shoot branching,tiller angle and environmental stress responses.The role of strigolactones in tea plant was briefly summarized in the current review,with an emphasis of the association of strigolactones on bud ecodormancy and shoot branching.The involvement of strigolactones on the biosynthesis of the tea characteristic metabolites flavonoids,caffeine and theanine were also discussed.Moreover,recent advances on the biosynthesis of strigolactones and its regulation by microRNAs and environmental stresses were also presented.This review provides a basis for future investigations underlying the mechanisms of strigolactones on bud winter dormancy and tea secondary metabolism.
