construction of the triple chy1chy2lut5 mutant, which is almost completely depleted in beta-xanthophylls. Quadruple chy1chy2lut2lut5 mutant, additionally carrying the lut2 mutation (affecting lycopene epsilon-cyclase) lacks lutein and shows a compensatory increase in beta-xanthophylls with respect to chy1chy2lut5 mutant.

construction of transgenic Nicotiana tabacum plants overexpressing LeLUT1, the transgenic plants have a higher lutein content, which is decreased in cold condition. Under chilling stress, the non-photochemical quenching values are higher in the transgenic plants than in the wild-type plants. Compared with the wild-type plants, the transgenic plants show lower levels of hydrogen peroxide, superoxide radical, relative electrical conductivity, and malondialdehyde content, and relatively higher values of maximal photochemical efficiency of photosystem II, oxidizable P700 of PSI, and net photosynthetic rate. The transgenic seedlings are less suppressed in growth and lose less cotyledon chlorophyll than the wild-type seedlings
