Abstract—Multidrug transporters are a class of secondary transporters and important transmembrane transporters which belong to facilitator superfamily (MFS). Multidrug transporters play critical roles in plant defense against various toxin stresses by exporting toxin outside the cell to reduce the accumulation of toxin compounds in body. In this article, structural features and mechanisms of MFS multidrug transporters responsed to plant stresses are described in details , such as defending against the infection of pathogen, exporting toxic compounds and transporting the heavy metal and so on. And then, the molecular modulation mechanism of plants MFS multidrug transporters is preliminarily discussed and the important roles of these transporters are defineds responsed to sresses in plants.

Index Terms—MFS, Multidrug Transporters, Plant.
