GM Tomatoes. Scientists in India have genetically modified tomatoes so that they can last for 45 days after harvesting. According to this press report, "India, the world's second-largest tomato grower, loses 35 to 40 percent of its crop to rotting before the product hits store shelves." The technique can also be applied to add shelf life to other fruits, including mangoes and bananas.
