additional information | 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 | Solanum lycopersicum |
