Figure 6: δ13C values of CH4 produced by tobacco plants supplemented with 13C-MET.
From: Abiotic methanogenesis from organosulphur compounds under ambient conditions
Black squares, diamonds and triangles show values measured for plants when treated with 50 mM (leaves), 10 μM (leaves) and 30 μM (roots) 13C-labelled MET, respectively; white symbols are for the corresponding treatments with unlabelled MET.
