| Ferredoxin-NADP+ Oxidoreductase of C. paradoxa Nucleus Encoded, but Cyanobacterial Gene Transfer from Symbiont to Host, an Evolutionary Mechanism Originating New Species  | | | | Abstract
| The nucleus encoded cyanoplast ("cyanellar") ferredoxin-N A D P+ -oxidoreductase (F N R) o f Cyanophora paradoxa, characterized by an N-terminal amino acid sequence, is compared with hom ologous sequences o f other photoautotrophic organisms. The high degree o f similari ty to the cyanobacterial sequences indicates a cyanobacterial origin. This could be a first direct demonstration o f an intertaxonic combination; a gene transfer from an original endocytobiont (cyanobacterium) to the nucleus o f its host, one o f the most important demands o f the Endo-symbiosis Theory, an evolutionary mechanism leading to the origin o f a new species. | | | |
