abstract：:Two 9-cis-epoxycarotenoid dioxygenase (NCED) cDNAs have been cloned from a petal library of Gentiana lutea. Both cDNAs carry a putative transit sequence for chloroplast import and differ mainly in their length and the 5'-flanking regions. GlNCED1 was evolutionary closely related to Arabidopsis thaliana NCED6 whereas G...
