Host plasmodesmaHost cell junctionHost


The host plasmodesma (plural host plasmodesmata) is a plasma membrane-lined channel that crosses the cell wall between two adjacent host plant cells and which allows a cytoplasmic exchange between the cells. It provides passage of ions and small molecules, but also of macromolecules such as RNA or proteins. Host plasmodesmata are sheathed by a host plasma membrane that is simply an extension of the cell membrane of the adjoining cells.
