- Understanding the impact of elevated CO₂ (eCO₂) in global agriculture is important given climate change projections. Breeding climate‐resilient crops depends on genetic variation within naturally varying populations. The effect of genetic variation in response to eCO₂ is poorly understood, especially in crop species. We describe the different ways in which Solanum lycopersicum and its wild relative S. pennellii respond to eCO₂, from cell anatomy, to the transcriptome, and metabolome. We further validate the importance of translational regulation as a potential mechanism for plants to adaptively respond to rising levels of atmospheric CO₂.
