To review the latest trends and developments of genetic modification

Some examples of developments of GM foods:

Crop-> Tomato
Genetic Modification->Genetically modified tomatoes contain four times the normal quantity of lycopene, a carotenoid.
Benefits->The carotenoids are powerful antioxidantswhich has the ability to lower the risk of heart disease and certain types of cancer.

Crop-> Broccoli
Genetic Modification-> Production of anti-oxidants and anti-carcinogens such as glucosinolate through genetic modification.
Benefits-> Antioxidants and anti-carcinogens prevent or slow down the aging of human cells.

Crop-> Golden rice
Genetic Modification-> Insertion of a gene from narcissus, another from a bacteria and a third conferring resistance to hygromycine (an antibiotic used in the selection of transgenic plants) into rice so that it produces beta-carotene, the precursor to vitamin A.
Benefits-> This rice could help prevent vitamin A deficiencies, which can cause diarrhea, measles, eye diseases and other health problems.

Crop-> Potato
Genetic Modification->Modification of potato to produce more starch.
Benefits->By producing more starch, it decreases fat absorption of the deep fried potato.

Latest news/ reports:

Addition of human genes into the rice
10 March 2007
US Department of Agriculture (USDA) started on three types of the rice to be planted over 1300 hectares in Kansason 28th feb 2007. Developed by Ventria Bioscience of Sacramento, California, the rice varieties have been given genes that either make the human breast milk proteins lactoferrin and lysozyme or the human blood protein albumin. The rice will make human proteins useful for treating infant diarrhoea in the developing world. Ventria plans to extract the albumin for industrial use in cell cultures, while the milk proteins are destined for rehydration drinks used to treat infants with diarrhoea. Trials on 140 children in Peru show the proteins give children a better chance of overcoming the condition and help them recover more than a day faster.
