Episode 440 - Turning off plants with a switch of a light

July 19, 2021

Turning off plants with a switch of a light. How can optogenetics be used to turn off photosynthesis. Stomata cells help a plant from feasting too much in times of famine. Stomata cells regulate how much photosynthesis plants undertake, but can they be regulated with light? How can Yeast be used to help plants fight back against fungus. Fungal infections can devastate crops and plants, but can we avoid dangerous fungicides? How can we protect plants from, fungi without damaging the environment? Can yeast grown proteins help stop fungal infections without killing all fungi?
