Abstract
|
|
|
|
The plasma membrane (PM) of eukaryotic cells is not only an outermost covering to contain and protect inner molecules required for cell viability but also a place where communications dynamically occur with adjacent cells and environments including pathogens. However the selective permeability limits the free translocation of information across the PM between cells. Therefore, eukaryotic cells have invented an elaborate machinery to safely export and import proteins and small molecules within a membrane-wrapped container called a vesicle. Upon infection, a host plant cell also actively interacts with a phytopathogen to achieve its goal, defense to frustrate the pathogen attempt. To understand communications between pathogens and plants, hence this review is mainly focused on molecular transport events that occur at the host PM during plant immune responses.
