Peanut leaf transcriptomic dynamics reveals insights into the acclimation response to elevated carbon dioxide under semiarid conditions
The photosynthesis analysis showed that 1) The light reaction was the most upregulated pathway by elevated [CO<sub>2</sub>] during water stress, 2) Photorespiration was downregulated across all stages, 3) Sucrose synthesis genes were upregulated by elevated [CO<sub>2</sub>] before stress, 4) Starch synthesis genes were upregulated by elevated [CO<sub>2</sub>] under drought periods, and 5) CO<sub>2</sub> regulation of sucrose and starch degradation was critical under drought periods. Our findings provide valuable insights into the molecular basis underlying the photosynthetic acclimation response to elevated [CO<sub>2</sub>] in peanuts.
