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
