In response to salinity or drought stress, many plants accumulate glycine betaine, which is a regulator of osmosis. In plants, the last step in betaine synthesis is catalyzed by betaine aldehyde dehydrogenase (BADH), a nuclear-encoded chloroplastic enzyme. Based on the conserved oligo amino acid residues of the published BADH genes from other higher plant species, a cDNA sequence, designated CtBADH, was isolated from safflower (Carthamus tinctorius L.) using a polymerase chain reaction approach.

Devolopmental and growth temperature regulation of omega-3 fatty acid desaturase genes in safflower (Carthamus tinctorius L.)

L. - L. Guan, Wu, W., Hu, B., Li, D., Chen, J. - W., Hou, K., and Wang, L., Devolopmental and growth temperature regulation of omega-3 fatty acid desaturase genes in safflower (Carthamus tinctorius L.), vol. 13, pp. 6623-6637, 2014.

Three ω-3 fatty acid desaturase genes (CtFAD3, CtFAD7, and CtFAD8) were isolated from safflower (Carthamus tinctorius L.). Transcript analysis showed that the highest transcript levels were detected for CtFAD3 and the low transcript levels were detected for CtFAD7 and CtFAD8 in flowers. This result indicates that CtFAD3 enzyme activity is important for fatty acid desaturation in flowers.
