Table I. Comparison of FA composition and total FA content at mature seed stage between tt2 mutant lines and their respective wild types.

Values are expressed in μg mg⁻¹ seed DW (in roman) and mol/% (in boldface). Data reported are mean values of five independent experiments (five biological repeats) ± se. Arrows indicate the significant differences (P ≤ 0.05).
