Zeaxanthin is an important dietary carotenoid but its abundance in our food is low. In order to provide a better supply of zeaxanthin in a staple crop, two different potato (Solanum tuberosum L.) varieties were genetically modified. By transformation with sense and antisense constructs encoding zeaxanthin epoxidase, zeaxanthin conversion to violaxanthin was(More)
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 GlNCED2 showed highest homology to tomato(More)
Suberin is a biopolyester found in specialized plant tissues, both internal and external, with key frontier physiological functions. The information gathered so far from its monomer and oligomer composition, and in situ studies made by solid state techniques, haven't solved the enigma of how the suberin polyester is assembled as a macromolecule.
