Thiamine metabolism genes in diatoms are not regulated by thiamine despite the presence of predicted riboswitches

Marcel Llavero Pasquina, Katrin Geisler, Andre Holzer, Payam Mehrshahi, Gonzalo I. Mendoza‐Ochoa, Shelby Newsad, Matthew P. Davey, Alison Gail Smith

The paper investigates whether predicted TPP riboswitches in diatoms regulate thiamine metabolism genes, finding they are not responsive to thiamine or its precursor.

Genetic transformation of the dinoflagellate chloroplast

Isabel C. Nimmo, Adrian C. Barbrook, Imen Lassadi, Jit Ern Chen, Katrin Geisler, Alison Gail Smith, Manuel Aranda, Saul Purton, Ross F. Waller, R. Ellen R. Nisbet, Christopher J. Howe

The paper demonstrates stable genetic transformation of dinoflagellate chloroplasts using a plasmid-like fragmented chloroplast genome, showing long-term expression and maintenance of introduced genes.
