A genetically modified tomato, or transgenic tomato, is a tomato that has had its genes modified, using genetic engineering. The first trial genetically modified food was a tomato engineered to have a longer shelf life (the Flavr Savr ), which was on the market briefly beginning on May 21, 1994. [ 1 ]
Due to the characteristics of the tomato, it was cheaper to produce than conventional tomato paste, resulting in the product being 20% cheaper. Between 1996 and 1999, 1.8 million cans, clearly labelled as genetically engineered, were sold in the major supermarket chains Sainsbury's and Safeway UK. At one point, the paste outsold normal tomato ...
The genetically modified organisms, including potato, tomato, and spinach are applied in the production of substances that stimulate the immune system to respond to specific pathogens. [15] With the help of recombinant DNA techniques, the genes encoded for viral or bacterial antigens could be genetically transcribed and translated into plant cells.
The tomato has a strong savoury umami flavor, and is an important ingredient in cuisines around the world. It is used in pizzas , pasta and other sauces , soups such as gazpacho , curries including dhansak and rogan josh , as juice, and in Bloody Mary cocktails .
The first genetically modified crop approved for sale in the U.S. was the FlavrSavr tomato, which had a longer shelf life. [51] First sold in 1994, FlavrSavr tomato production ceased in 1997. [111] It is no longer on the market. In November 2014, the USDA approved a GM potato that prevents bruising. [112] [113]
Genetically modifying plants is an important economic activity: in 2017, 89% of corn, 94% of soybeans, and 91% of cotton produced in the US were from genetically modified strains. [23] Since the introduction of GM crops, yields have increased by 22%, and profits have increased to farmers, especially in the developing world, by 68%.
It will hybridize with common domestic tomatoes. [9] There are annual, biennial, and perennial varieties. [10] Solanum pimpinellifolium is important in tomato breeding.. Its relatedness to tomatoes [11] and ability to freely cross with them has allowed it to be used for the introduction of disease resistance traits in tomato varieties, as well as in the study of the genetic control of tomato ...
Parthenocarpy is also desirable in fruit crops that may be difficult to pollinate or fertilize, such as fig, tomato and summer squash. In dioecious species, such as persimmon , parthenocarpy increases fruit production because staminate trees do not need to be planted to provide pollen.
