Silencing suppressor, symptom 1 Plant–Virus Interactions 13 determinant, Avr determinant) are being explored and characterized. Increased efforts will be made toward understanding differences in interactions of viruses with different cell/tissue types. This latter objective will be aided by the continual development of new techniques; for example, laser capture microscopy/microdissection that will allow genomic, proteomic, and metabolomic analysis of individual virus-infected cells (107). As virologists sort out the mechanisms that lead to symptom development and activation of plant defenses, increasingly there will be a shift toward the host side of the host–virus interaction.
The systemic spread of plant viruses proceeds in several distinct stages. First, the virus (in the form of virions or nucleic acid protein complexes) moves intracellularly from the sites of replication to plasmodesmata (PD), which are unique intercellular membranous channels that span cell walls linking the cytoplasm of contiguous cells. The virus then transverses the PD to spread intercellularly (cellto-cell movement). Virus systemic movement between organs (long-distance movement) occurs through vascular tissue, usually phloem sieve tubes.
