Increased Bundle Sheath Leakiness of CO2 During Photosynthetic Induction Shows a Lack of Coordination between the C4 and C3 Cycles

Long, S.P., Wang, Y., Stutz, S.S. Sept. 7, 2022. “Increased Bundle Sheath Leakiness of CO₂ During Photosynthetic Induction Shows a Lack of Coordination between the C₄ and C₃ Cycles.” University of Illinois Urbana-Champaign. DOI: 10.13012/B2IDB-1181155_V1.

We developed a new application of isotopic gas exchange which couples a tunable diode laser absorption spectroscope (TDL) with a leaf gas exchange system, analyzing leakiness through induction of C₄ photosynthesis on dark to high-light transitions. The youngest fully expanded leaf was measured on 40-45 day-old maize (B73) and sorghum (Tx430). Detail definition of each variable in raw Li-6400XT and Li-6800 (in “Original_data_AND_Data_processing_code.zip”) is summarized in: https://www.licor.com/env/support/LI-6800/topics/symbols.html#const
