SAT and OASTL enzyme activities in developing embryos of T₂ transgenic narrow leaf lupins and controls. Each bar represents the mean ±SE for T₂ embryos from one T₁ transgenic plant. Between two and five technical replicates were performed, with extracts from 1–5 independent subsamples of embryos for each T₁ plant. Symbols indicate the significance of the differences between each mean value and that of the wild-type control, cv Kalya (^#P <0.1; *P <0.05; **P <0.01). Kalya #1 and #2 and SSA #1 and # 2 represent measurements for pooled embryo extracts for two separate plants of either the non-transgenic control Kalya or a transgenic lupin line homozygous for the SSA transgene.
