Discovered mechanisms for plants to have four different genotypes

One of the first chemical reactions that children are known for is photosynthetic reactions, combining carbon dioxide, water and solar energy to produce organic compounds.

Many of the plants around the world have the most important humanity in the world, as plants have not developed the ability to incorporate these ingredients. Instead, they take their chloroplasts indirectly by "stealing" them from other organisms.

In some cases, this makes the algae have a diverse and different set of genes, the evolution equivalent to that of a 'turducken' (turducken is a seasonal dish including: a boneless chicken stuffed into one The bone-drawn duck, which is itself stuffed into a boneless turkey.

The chloroplast was originally developed from photosynthetic bacteria by primary symbiosis, in which a bacterium or other primitive nucleus plants are embedded deep inside by a typical nucleus host. The chloroplasts of red and green algae then came to reside in other host plants, plants that had no previous photosynthetic nuclei with secondary symbiosis. These events have contributed to the global diversity of photosynthetic organisms that play a very important role in regulating and maintaining the global carbon cycle.

In most organisms that are photosynthesized by this mechanism, the kernels from digested algae cells have disappeared, but in some cases it remains as a remaining organ known as a nucleomorph (the nucleus of symbiosis in maximum collapsed form). Such creatures have four different sets of genes.

To better understand secondary symbiosis and why nucleomorphs persist in some organisms, an international team of 73 researchers at 27 research institutions, including DOE JGI (US Department of Energy Joint Genome Institute), has sequenced and analyzed the genome and transcription of two small algae. The team led by John Archibald from Canada's Dalhousie University published their findings in the journal Nature today November 29, 2012. t
