Abstract
RAYA-PEREZ, J. C. and AGUIRRE-MANCILLA, C. L.. Appearance and evolution of C4 photosynthesis. Rev. Chapingo ser. cienc. for. ambient [online]. 2008, vol.14, n.1, pp.45-50. ISSN 2007-4018.
The photosynthesis type C4 had its origin 7-5 millions years ago in several genera of plants. The atmospheric diminution of CO2 concentration leads to a concentrative mechanism. Some studies of genes and enzymes than participate in this pathway shown several changes than have occurred in DNA and proteins in order to adapt them for a new function, CO2 concentrating mechanism. This mechanism avoid Rubisco's oxygenase function.
