Abstract excerpt
Plants have intercellular channels, plasmodesmata (PD), that span the cell wall to enable cell-to-cell transport of micro- and macromolecules. We identified an Arabidopsis thaliana embryo lethal mutant increased size exclusion limit 1 (ise1) that results in increased PD-mediated transport of fluorescent tracers. The ise1 mutants have a higher frequency of branched and twinned PD than wild-type embryos. Silencing...
