Answer: Golden rice and Bt cotton (also Flavr Savr tomato).

  • Golden rice: transgenic rice carrying genes for β-carotene (provitamin A) synthesis in the grain; used to fight vitamin A deficiency.
  • Bt cotton: carries the cry gene of Bacillus thuringiensis, whose toxin kills bollworms, so less insecticide is needed and yield increases.
  • Flavr Savr tomato: the activity of the fruit-softening enzyme polygalacturonase is blocked, giving delayed ripening and longer shelf life.
