Opening up the communication channels: recent insights into plasmodesmal function

Curr Opin Plant Biol. 2000 Oct;3(5):394-9. doi: 10.1016/s1369-5266(00)00102-3.


The past year has seen significant advances in our understanding of the function and regulation of plasmodesmata. Notably, we have learned that plasmodesmata undergo dynamic changes during development and may participate in long-range communication through the transmission of RNA signals. Biochemical studies have enriched our understanding of a putative plasmodesmal receptor and of plant factors involved in viral cell-to-cell movement.
