isolation and analysis of a naturally occuring tomato zeaxanthin epoxidase mutant, high-pigment 3 or hp3, that accumulates 30% more carotenoids in the mature fruit than the wild-type, and higher concentrations of carotenoids and chlorophyll in leaves and the pericarp of green fruit, leaves of the mutant lack violaxanthin and neoxanthin, and flowers contain only minute quantities of these xanthophylls, the abscisic acid content is reduced by 75%, which leads to enlargement of the plastid compartment size, probably by increasing plastid division, thus enabling greater biosynthesis and a higher storage capacity of the pigments, phenotype, overview |

seed dormancy is impaired in mutants of conversion of zeaxanthin into violaxanthin by zeaxanthin epoxidase, seed dormancy is restored by the introduction of the Arabidopsis thaliana ZEP gene under the control of promoters inducing expression during later stages of seed development compared to wild type Nicotiana plumbaginifolia ZEP, and in dry and imbibed seeds, alterations in the timing and level of ZEP expression do not highly affect the temporal regulation of ABA accumulation in transgenic seeds, despite notable perturbations in xanthophyll accumulation, overview |

transgenic Arabidopsis thaliana plants overexpressing the AtZEP gene exhibit more vigorous growth under high salt and drought treatments than wild-type plants. In addition to enhanced de novo abscisic acid biosynthesis, they also exhibit much higher expression of the endogenous stress-responsive genes RD29A and Rab18 than wild-type plants under salt stress, and the stomatal aperture of the AtZEP-overexpressing plants is smaller than wild-type plants after exposure to light, overview |
