Key Findings
2.3h shift in stomatal opening under 800ppm CO2
TOC1 transcription factor mediates the shift
Circadian adaptation to future CO2 levels
Original Abstract
We show that stomatal opening follows a modified circadian rhythm under 800ppm CO2, with peak aperture shifting 2.3 hours earlier. The transcription factor TOC1 mediates this shift, providing a mechanism for how plants may adapt gas exchange patterns under future atmospheric conditions.

Species Mentioned
Arabidopsis (rockcress) is a genus of small flowering plants in the cabbage and mustard family, Brassicaceae. Arabidopsis species are native to temperate and subarctic Eurasia and North America, North Africa, and the mountains of eastern tropical Africa. This genus is of great interest since it c...
