Subcellular Immunolocalization of the Coat Protein of Two Potexviruses in InfectedChenopodium quinoa

The production of coat protein is necessary for cell-to-cell transport of potexviruses in plants. To investigate the role of coat protein in the movement process, the intracellular distribution of coat protein in tissues infected with either of two potexviruses was studied using immunocytochemical procedures. We report that coat protein antigens are associated with the plasmodesmata of infected cells.
