FIGURE 4.

Representative fatty acid profiles of transgenic GA7_mod-B Brassica napus events ranging from moderate to high levels of DHA. The bottleneck step is typically Δ6-desaturation, with other enzymatic steps tending to occur at high or very high efficiency. Bracketed values above the pathway describe the total EPA, DPA and DHA levels. Enzyme conversion efficiencies are shown in parentheses and the ω3 to ω6 ratio (all chain lengths) for each event is reported. (A,B) Representative events with low copy (1–3 copies), and (C) representative event with high copy (> 3 copies) of the T-DNA inserts.
