http://pakbs.org/pjbot/papers/1680767412.pdf WebPreviously, we characterized the first dedicated enzyme in the crocin biosynthetic pathway, carotenoid cleavage dioxygenase2 (CsCCD2), which cleaves zeaxanthin to yield crocetin dialdehyde. In this work, we identified six putative aldehyde dehydrogenase ( ALDH) genes expressed in C. sativus stigmas.
