Construction and characterization of a phycobiliprotein-less mutant of Synechocystis sp. PCC 6803

  • Ghada Ajlani
  • Claudie Vernotte


A mutant strain of the cyanobacterium Synechocystis PCC 6803, called PAL, (PC-, ΔapcAB, ΔapcE), lacking phycocyanin, allophycocyanin and the core-membrane linker (Lcm), was constructed. The strain was characterized by absorption and fluorescence spectroscopy. The mutant compensates for the absence of the major PS II antenna by increasing its PS II / PS I ratio. It is stable and grows well albeit more slowly than wild type.
