Potential ecological roles offlavonoidsfromStellerachamaejasme

摘要

StellerachamaejasmeL. (Thymelaeaceae), a perennial weed, distributes widely in the grasslands of Russia, Mongoliaand China. The plant synthesizes various secondary metabolites including a group offlavonoids. To our knowledge,flavonoids play importantroles in the interactions between plants and the environment. So, what are the benefits toS.chamaejasmefrom producing theseflavonoids? Here, we discuss the potential ecological role offlavonoids fromS.chamaejasmein protecting the plant from insects and other herbivores, as well as pathogens and competing plantspecies, and new data are provided on the phytotoxicity offlavonoids fromS.chamaejasmetowardPoaannuaL.
