A cDNA (SeFAD2) encoding a microsomal omega -6 desaturase was characterized in association with its temporal expression and changes in linoleic acid levels in sesame (S. indicum Dan-Baek) oilseeds. Much higher sequence identities of the SeFAD2 protein were found with microsomal omega -6 (71-81%) than with plastidial omega -6 desaturases (22-24%) and the sequences within the conserved histidine boxes were different from those of other plant histidine boxes examined.
