Abstract

In higher plants the direct cytoplasm to cytoplasm intercellular movement of water, nutrients, small signaling molecules, and, in certain cases, of macromolecules is via plasmodesmata (singular plasmodesma), highly specialized gatable cytoplasmic trans-wall channels that interconnect contiguous cells. In addition to their normal function, plasmodesmata are apparently exploited by plant viruses in order to spread from cell to cell. Since the cell wall which encases the plant protoplast constitutes an impermeable barrier, plant viruses have developed strategies which allow them to exploit the natural channels connecting contiguous cells, the plasmodesmata, as conduits for cell-to-cell spread.
