Stomata from intact, attached leaves of Arabidopsis illuminated with blue, red, and green light in a growth chamber, increases and decreases their aperture in response to light.
Find the CORRECT statements from the above graph.
i) Stomatal aperture increases when the green light is turned off, and close when the green light is turned on again
ii) Stomata from the phototropin-less double mutant phot1/phot2 respond to blue light and open further when green light is turned off
iii) stomata from the zeaxanthin less mutant npq1 do not respond to blue light and least effect to opening of the stomata further when green light is turned off
iv) the npq1 mutant and phot1/phot2 double mutant response indicate that the green reversal of the blue-light response requires zeaxanthin but also phototropin
