| The blue light response of guard cells is mediated by the chloroplastic carotenoid, zeaxanthin. |
| Cataract patients also tend to be deficient in vitamin A and the carotenes, lutein and zeaxanthin. |
| During this interaction, energy is dissipated via a charge exchange mechanism in which the zeaxanthin gives up an electron to the chlorophyll. |
| Obviously, in their case, zeaxanthin cannot be an important factor in energy dissipation. |
| The recombinant protein was assayed for cleavage activity towards zeaxanthin. |
| The first major breakthrough in understanding the molecular genetics of ABA biosynthesis involved the cloning of zeaxanthin epoxidase. |
