Table 1 Summary of omega-3 FAD genes cloned from cotton

*Gene nomenclature includes the first three letters of the plant genus and species, followed by the gene name, and ending with the genome designation (A for G. herbaceum or the A subgenome of G. hirsutum, or D for G. raimondii or the D subgenome of G. hirsutum). The FAD3-2 gene is duplicated in both G. herbaceum and G. hirsutum, and the paralogs are designated FAD3-2.1 and FAD3-2.2. The coding sequence of FAD3-2.2 contains multiple in-frame stop codons and a frame-shift mutation and thus is likely a pseudogene. The single FAD3-2 gene within G. raimondii is designated FAD3-2.1 for clarity to indicate that it is more similar to the FAD3-2.1 sequence in the A genome-containing species. GenBank accession numbers are provided in Additional file 4.
