Increased oleic acid content in soybean mutant FAD2-1A mutant lines compared to FAD2-1A wild-type lines from field produced seeds in two years. Histograms represent the mean oleic acid content as a percentage of the seed oil for 25 individual seed samples representing five plants from each line listed on the x-axis. Error bars represent plus and minus one standard deviation of the mean. For each line, the FAD2-1A, FAD3A, and FAD3C genotypes are listed below the line name; lowercase letters represent the mutant case, and uppercase letters represent the wild-type case. Line 17D is the result of mutagenesis of line Williams 82, and contains an S117N missense mutation of FAD2-1A (bolded for comparison); M23 contains a genomic deletion of FAD2-1A [18]; 10–73 contains mutant alleles of FAD3A and FAD3C, which reduce linolenic acid levels but do not affect oleic acid levels [33]; KB05-7 is a derivative of a cross between 10–73 and M23 which combines mutant alleles of FAD2-1A, FAD3A, and FAD3C.
