Fig. 3 in Fluoroacetate distribution, response to fluoridation, and synthesis in juvenile Gastrolobium bilobum plants

Fig. 3. Labeling of metabolites in expanding and young expanded leaves fed with each of the three 13C-precursors tested, i.e., adenosine (ribose-13C), 13C -serine, 5 3 and 13C -acetate. (A) Isotope ratios (M 5/M 0 peak areas) of the adenosine metabolite inosine. (B) Isotope ratios (M 2/M 0 peak areas) of the serine metabolite 2 + + + + pyruvate. (C) Isotope ratios (M+2/M+0 peak areas) of the acetate metabolites glutamate and N-acetylarginine. Mean values are marked by horizontal bars (± standard error, n = 2 or 3). Asterisks indicate significant differences between a precursor-fed mean and the corresponding unlabeled control mean: *, P <0.05; **, P <0.01, ***, P <0.001 (pairwise t-tests, square root transformed data).
