Fig. 1 in Fluoroacetate distribution, response to fluoridation, and synthesis in juvenile Gastrolobium bilobum plants

Fig. 1. Pattern of fluoroacetate accumulation in juvenile Gastrolobium bilobum plants. (A) Plants at the stage used in experiments. The red line demarcates upper leaves from lower leaves. (B) Fluoroacetate (Facetate) levels in upper and lower leaves of eight to ten plants irrigated without or with supplemental sodium fluoride. Each data point is for leaves from a single plant. Mean values are marked by horizontal bars (± standard error) and shown above each set of points. Asterisks indicate means that differ significantly from each other: *, P> 0.05; **, P> 0.01 (pairwise t-tests). FW, fresh weight. (C) Positive correlation between fluoroacetate levels in upper and lower leaves of the same plants. R2 significant at P <0.05*, <0.01**. (D) Fluoroacetate levels in leaf, stem, and root material from plants given supplemental sodium fluoride. Data are for three independent samples, each consisting of organs from 12 pooled plants. Mean values are marked by horizontal bars (± standard error) and shown above each set of points. Means marked with the same letter are not significantly different from each other (P> 0.05, one-way ANOVA, Tukey HSD).
