Table I. Comparison of fatty acid composition of Arabidopsis mutant lines with the wild type

Data represent measurements of three to five homozygous lines (means ± se). Student’s t test was applied to the data; asterisks indicate that these values were statistically significantly different from the wild type (Col-0) at P < 0.05.
