Disease relevance of C05434

Further introduction of the lycopene cyclase gene from E. uredovora (crtY) or the higher plant Capsicum annuum (Icy) resulted in the production of a bicyclic carotenoid, 7,8-dihydro-beta-carotene, via monocyclic beta-zeacarotene. zeta-Carotene was also found to be cyclized to bicyclic 7,8,7',8'-tetrahydro-beta-carotene by the Erwinia cyclase [1].

High impact information on C05434

Increased amounts of beta-zeacarotene and gamma-carotene were realized in the PD-1 parent and in the F1 hybrid [2].
