Main Research Areas (1982-2005)

Adaptation of cyanobacteria to their environment

  • Adaptation of Synechococcus elongatus PCC 7942, Thermosynechococcus elongatus BP-1, and Synechocystis sp. PCC 6803 to iron deficiency and to oxidative stress

L-Arginine metabolism in cyanobacteria

  • Characterization and functional analysis of an L-amino acid oxidase with high specificity for basic L-amino acids (L-arginine being the best substrate) in Synechococcus elongatus PCC 6301/PCC 7942,
  • Cyanophycin synthesis in Synechocystis sp. PCC 6803: Comparative analysis of cyanophycin synthesis in Synechocystis sp. PCC 6803 wild type and a PsbO-free mutant
  • Characterization of a small photosystem II peptide with a low L-arginine metabolising activity in tobacco and Synechocystis sp. PCC 6803

Redox regulation

  • Charcterisation of the histidine kinase Slr1759 having a complex domain structure in Synechocystis sp. PCC 6803.

Production of cyanophycin in plants
