  1. Comparison of fatty acids profiles (%) of HR E1.5 hairy roots with Echium asperrimum roots, E. acanthocarpum seeds and leaves, and transgenic Arabidopsis seeds expressing the E. plantagineum Δ6-desaturase gene. n-6 and n-3 Δ6-Desaturation Indexes were calculated as 18:3n-6/(18:3n-6+18:2n-6) and 18:4n-3/(18:4n-3+18:3n-3) respectively. Double Bond Indexes (DBI) were calculated as [(% 18:1) +2*(% 18:2) +3*(% 18:3) +4*(18:4)]/100. Numbers within brackets indicate reference number.
