Fig. 2: Example time series showing the 13C-labeling dynamics of leaf isoprene and methanol in the light under constant environmental conditions including optimal conditions for photosynthesis (1200 µmol m−2 s−1 PAR, 32 °C leaf temperature, and 900–1000 ppm reference 13CO2).

Note the rapid and near complete 13C-labeling of isoprene emissions, and the comparably slower and incomplete labeling of 13C-methanol emissions.
