    K J Oparka
    Unit of Cell Biology, Scottish Crop Research Institute, Invergowrie, Dundee, United Kingdom
    Cell 97:743-54. 1999
    ..Contrary to dogma that plasmodesmata have a size exclusion limit below 1 kDa, the data demonstrate that nonspecific "macromolecular trafficking" is a general feature of simple plasmodesmata in sink leaves...

    Nieves Medina Escobar
    Programme of Cell to Cell Communication, Scottish Crop Research Institute, Invergowrie, Dundee DD2 5DA, United Kingdom
    Plant Cell 15:1507-23. 2003
    ..This virus-based system represents a method for high-throughput functional genomic study of plant cell organelles and allows the identification of unique proteins that associate with specific subcompartments within organelles...
  3. ncbi request reprint Dynamic changes in the frequency and architecture of plasmodesmata during the sink-source transition in tobacco leaves
    I M Roberts
    Unit of Cell Biology, Scottish Crop Research Institute, Dundee

    Unit of Cell Biology, Scottish Crop Research Institute, Invergowrie, Dundee DD2 5DA, UK
    J Exp Bot 52:173-7. 2001
    ..Contrary to published data, these observations suggest the presence of a functional symplastic pathway between Cuscuta and its hosts, and demonstrate a considerable capacity for macromolecular exchange between plant species...
