Agriculture and ecosystems are tipping toward collapse due to land use and climate extremes. Irreversible feedbacks in the land system can lock in food insecurity, biodiversity loss and a hot house world.
In order to sustain and improve cotton (Gossypium hirsutum) production in future climates with increasingly hot mean annual temperatures and more frequent and extreme heatwaves, developing climate-adapted cotton cultivars is required.
Many photosynthetic organisms employ a CO2 concentrating mechanism (CCM) to increase the rate of CO2 fixation via the Calvin cycle. CCMs catalyze ≈50% of global photosynthesis, yet it remains unclear which genes and proteins are necessary for a CCM to function.
