Identification and Characterization of Pleiotropic Drug Resistance(PDR)transporters in Salix purpurea and their Roles in Response to Various Heavy Metal Stresses

Pleiotropic Drug Resistance(PDR)transporters belonging to the ABCG subfamily of ATP-binding cassette(ABC)transporters are identified to involve in heavy metal tolerance.Willow is an ideal candidate for the phytoremediation of heavy metals due to its large biomass,high tolerance,and extraordinary accumulation of heavy metals.However,the definitive phylogeny and heavy metal transport mechanisms of the PDR family in willow remain unknown.Here,21 PDR genes in Sa…查看全部>>
