New Phytologist, Volume 249, Issue 5, Page 2386-2401, March 2026.
Summary Many plants maximize photosynthesis by using a CO2‐concentrating mechanism (CCM). Based on physiology, the freshwater plant Ottelia alismoides has three CCMs: C4 metabolism (NAD‐malic enzyme (NAD‐ME) subtype) and bicarbonate‐use during the day plus crassulacean acid metabolism (CAM) at night and lacks Kranz anatomy. Here, we combined a range of
