Genetic engineering of carotenoid formation in tomato
The health promoting and aesthetic qualities of carotenoids have triggered considerable interest in enhancing their levels in crop plants, particularly in fruits and vegetables. One of the main crops of choice is the tomato, since it is readily available in both fresh and processed produce. There are several reports of the use of genetic engineering to increase levels of lycopene and \(\upbeta\)-carotene in ripe fruit. This review will highlight the strategies used to achieve these goals by comparing the use of different genes from plants and microorganisms as well as the choice of promoters.
