and there are potentially a range of different genetic mechanisms to choose from. Many of the proteins used in the C4 pathway are taken from C3 plants

So geneticists are painstakingly comparing the genetic code of the two leaf types to find out what makes a C4 leaf a C4 leaf.

If they do find the genetic code for C4, and it works in rice, Langdale says it will be fairly simple to convert other crops, such as wheat, barley and rapeseed (canola).

But what is certain is that the survivors of these menagerie experiments in the human garden will produce a genetic legacy.

There is huge opposition to genetically modified crops in many countries, with some groups citing safety concerns and others ethical, arguing that the developing world should not be used as a laboratory to test such crops.

#Scientists Crack the Genetic Code of Wheat Wheat is the worlds oldest and most important crops.

British scientists have decoded the genetic sequence of wheat one of the worlds oldest and most important crops a development they hope could help breed better strains of the global food staple.

Although the genetic sequence being published Friday remains a rough draft, and additional strains of wheat need to be analyzed for the work to be truly useful,

Other crops have had their genetic codes unscrambled within the past few years rice in 2005, corn in 2009,

The reason for the delay in analyzing wheats genetic code, Hall said, was that the code is so massive far larger than corn

Although the code may yet see use by genetic engineers hoping to craft pesticide-resistant strains of wheat,

Once they know which genetic markers to look for Hall said, new forms of wheat could be rolled out far faster.
