^aNT, non-transgenic; TF5 and TF6; transgenic IbFAD8 overexpression lines #5 and #6, respectively.

^bData are expressed as mole percentage for compositions based on peak areas obtained by gas chromatography (GC) analysis. Numbers in parentheses indicate content of each fatty acids (g/100 g). Values represent mean ± standard deviation (SD) of three independent replicates. *p < 0.05, **p < 0.01.
