Abstract

A paraquat inducible protein is supposed to play a role in the resistance of horseweed Conyza canadensis (L.) Cronq., which presumably functions by carrying paraquat to a metabolically inactive compartment. Here we studied the effect of transporter inhibitors (CCCP, DCCD, TPP and vanadate) on the decrease of functional activity caused by paraquat in order to reveal the possible roles of different types of transporters in the resistance mechanism. Results presented here imply the participation of not directly energized antiporters in paraquat sequestration.
