Fig. 2. Amino acid alignment of a portion of the soybean and Arabidopsis FAD3 protein sequences. Identical amino acids are highlighted in black while similar amino acids are highlighted in gray. The wild-type and CX1512-44 GmFAD3C (CX1512-44C) alleles are shown from amino acid 103 to 152. A SNP in the coding sequence results in a G128E mutation (indicated above the alignment with an asterisk) for the CX1512-44 allele. Histidine-rich region 1b (Shanklin et al., 1994) is underlined.
