Figure 3. An overview of GmFAD3A alleles and mutations found in low linolenic acid soybean lines. Schematic diagram of GmFAD3A alleles found in the low linolenic acid soybean lines A5, J18, M5, CX1512-44, C1640, and PI 361088B. Exons are indicated by black boxes and introns by horizontal lines. To the right of the gene schematics is a list of the amount (g linolenic acid kg^–1 of oil) of linolenic acid levels in seeds of the various lines. Also indicated is whether a rapid molecular assay has been published to test for the presence of that particular allele. Relevant references for each line or mutant are also listed.
