From the Ted Talk by Jill Farrant: How we can make crops survive without water

Unscramble the Blue Letters

In the study that I'm going to talk to you about, my collaborators used a drought-induced promoter, which we discovered in a rsreteriucon plant. The nice thing about this pmrteoor is that we do nothing. The plant itself senses dughrot. And we've used it to drive antioxidant genes from resurrection plants. Why antioxidant genes? Well, all stresses, particularly drought stress, results in the formation of free radicals, or rveatcie oxygen species, which are highly damaging and can cause crop dateh. What antioxidants do is stop that damage.

In the study that I'm going to talk to you about, my collaborators used a drought-induced promoter, which we discovered in a resurrection plant. The nice thing about this promoter is that we do nothing. The plant itself senses drought. And we've used it to drive antioxidant genes from resurrection plants. Why antioxidant genes? Well, all stresses, particularly drought stress, results in the formation of free radicals, or reactive oxygen species, which are highly damaging and can cause crop death. What antioxidants do is stop that damage.
