Soy Beans

Soy beans, one of the most important global sources of protein and oil, is now the first major crop lagume species with a published complete draft genome sequence. As we talked about in class last week, food companies changed the genes of soybeans to increases in the plant's oil content to promote the use of soybean oil as a biofuel, make bigger crops, improved resistance to pests an diseases that currently claim large percentages of soybean crops, even to make improvement in the digestibility of soy beans by animals and humans.Yes, it seems like is good for us in many ways, but think about it, after that many genome sequences, are we eating the real soybeans, or the industury stuff made by the food companies?

Rices' different grown condition

Rice is one of the most important crops worldwise, as it feeds over half of the world's population. There are different tpes of rice, such as domesticated rice, which is an important supply of world's rice but genetically static and not able to change its growing conditions. So people plant rices which its genes changed.But not the change by people like we talked last week, their genes changed by theirselfs naturally. In Thailand, peoole compared the genetic variation among the same variety of rice grown in different fields and villages. The genetics of the rice population fits the isolation by distance model, much like a native plant species. The further apart fiels are, the more genetically distinct they are.A number of crops grown today have been genetically optimized to consistently gice a large yield.Seeds are purchased from asupplier and the plants are all genetically similar.
