About
Characteristic for diatoms are their ability to create hierarchically nano- and micropatterned siliceous frustules. Exactly how silica polymerization and nanopatterning takes place inside the silica deposition vesicle (SDV) of diatoms is still largely unknown. A previous transcriptome study from our lab revealed a family of previously uncharacterized diatom-specific transmembrane proteins related to Silicanin-1, the first protein to be localized in the SDV membrane. We hypothesized that the Silicanin family is associated with the SDV membrane and is likely involved in silica biomineralization of the diatom frustule. A possibility is that Silicanins interact with the cytoskeleton through adapter proteins. By knocking out members of the Silicanin family in the diatoms Phaeodactylum tricornutum and Thalassiosira pseudonana we can further investigate the role of Silicanins and look at the effects on frustule patterning and structure.
