A cDNA sequence, designated CtFAD2-1 and putatively encoding a delta-12 fatty acid desaturase, was isolated from total RNA of immature normal-type safflower (Carthamus tinctorius L.) seeds using a PCR approach. The deduced amino acid sequence showed three histidine boxes characteristic of all membrane-bound desaturase and a C-terminal endoplasmic reticulum(More)
The endoplasmic reticulum (ER)-associated oleate desaturase (FAD2) is the key enzyme responsible for the production of linoleic acid in plants. In safflower, a seed-type FAD2 gene (CtFAD2-1) has been isolated previously. In this study, two different cDNA sequences, designated CtFAD2-2 and CtFAD2-3, encoding two microsomal oleate desaturases have been(More)
