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 ]
This is a list of antioxidants naturally occurring in food. Vitamin C and vitamin E – which are ubiquitous among raw plant foods – are confirmed as dietary antioxidants, whereas vitamin A becomes an antioxidant following metabolism of provitamin A beta-carotene and cryptoxanthin.
Aside from tomatoes or tomato products like ketchup, it is found in watermelons, grapefruits, red guavas, and baked beans. [4] It has no vitamin A activity. [4]In plants, algae, and other photosynthetic organisms, lycopene is an intermediate in the biosynthesis of many carotenoids, including beta-carotene, which is responsible for yellow, orange, or red pigmentation, photosynthesis, and ...
Tomatoes also contain a beneficial compound called lycopene, which has antioxidant properties. Lycopene is more available when exposed to heat, like in cooked tomato products such as tomato sauce.
Tomato plants are vines, becoming decumbent, and can grow up to 3 m (9.8 ft); bush varieties are generally no more than 100 cm (3 ft 3 in) tall. They are tender perennials, often grown as annuals. [40] [41] Tomato plants are dicots. They grow as a series of branching stems, with a terminal bud at the tip that does the actual growing.
Fruits including tomatoes, tomatillos, eggplant/aubergine, bell peppers and chili peppers, all of which are closely related members of the Solanaceae.. The Solanaceae (/ ˌ s ɒ l ə ˈ n eɪ s i. iː,-ˌ aɪ /), [3] or the nightshades, is a family of flowering plants that ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of ...
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 ...
To address this, tomatoes intended for shipping are often picked while they are unripe, or "green", and then prompted to ripen just before delivery through the use of ethylene gas, which acts as a plant hormone. The downside to this approach is that the tomato does not complete its natural growing process, and the final flavor suffers as a result.
