This review  pretends  to  illustrate a very interesting phenomenon  in  nature: the  secondary loss of the  photosynthetic function and its effects in chloroplast and mitochondrial  DNA. Here it is described how plastid  DNA has been reduced loosing those genes which encode for photosynthetic proteins. An example of the  mitochondrial DNA of a colouress alga is also explained. An hypothesis is proposed where the  number o f mitochondrial genes is maintained in  this  colourless organisms due to the energetic demand  on the organelle.

ABSTRACTOrganic biological hybrid systems, accessible by covalent functionalization of photosynthetic proteins with molecular antennas, represent a promising novelty to enhance natural photosynthesis. In this paper, we present the successful bioconjugation of a commercial fluorophore, fluorescein isothiocyanate (FITC), to the photosynthetic reaction center RC from the bacterium Rhodobacter sphaeroides strain R26. The resulting hybrid outperforms the pristine protein in hole-electron couple generation yield, exclusively at wavelengths where the fluorophore absorbs while the protein does not.
