Alignment of NtFAD2–1a, NtFAD2–1b, NtFAD2–2a, NtFAD2–2b, AtFAD2, and OsFAD2 protein sequences. Multiple sequence alignment was performed using DNAMAN 8.0. Black and gray shading indicate conserved and similar amino acids, respectively. Open boxes represent H boxes, while the transmembrane α-helices (TM) and endoplasmic reticulum (ER) localization signal are underlined
