      Good question, I’m glad you have read my profile!!

      I know this because I have a plant that responds well to high sunlight. This gene is switched on when normal plants are in high light.

      I then removed the sugar transporting gene from this plant, and it can no longer respond to high sunlight.

      I have also measured the sugars in the chloroplast in both these plants, and you get almost no sugar in the chloroplasts of plants without the gene.

      So I can show that the gene transports sugars into the chloroplast, and that the gene is switched on in high light intensity.
