Abstract
The genetic basis for susceptibility or nonsusceptibility
of plants to viruses is understood poorly. Two
selectable tobacco etch virus (TEV) strains were developed for
identification of Arabidopsis thaliana mutants with either
gain-of-susceptibility or loss-of-susceptibility phenotypes.
These strains conferred a conditional-survival phenotype to
Arabidopsis based on systemic expression of herbicide resistance
or proherbicide sensitivity genes, thereby facilitating
mass selections and screens for Arabidopsis mutants that
enhance or suppress TEV replication, cell-to-cell movement,
or long-distance movement. A multicomponent mechanism
that restricts systemic invasion of TEV was identified through
isolation of gain-of-susceptibility mutants with alterations at
two loci.
