| Outline of Final Research Achievements |
Brown algae show multicellularity and possess cellular connections called plasmodesmata which enable exchange of molecules between the neighboring cells. Plasmadesmata take tubular structure with 10 - 20 nm in diameter, and vary appearance and distribution with the developmental stages. Some new findings concerning brown algal plasmodesmata were given in this study as follows; 1) plasmodesmata are divided into primary and secondary plasmodesmata as in land plants, 2) plasmodesmatal size exclusion limit are set between 20-40 kDa in multiseriate species, and 3) pit fields in which plasmodesmata concentrate one place on the cross wall pass molecules less than 10 kDa to the next cell.
