Secondary loss of photosynthesis: the case of some colourless algae and some parasites
AbstractThis 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.
