1.14.14.158 gene LeLUT1, DNA and amino acid sequence determination and analysis, quantitative RT-PCR expression analysis, expression of gene LeLUT1-GFP fusion protein in chloroplasts of Arabidopsis thaliana mesophyll protoplasts, quantitative real-time PCR expression analysis Solanum lycopersicum

Protein Variants

EC Number Protein Variants Comment Organism
1.14.14.158 additional information 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 Solanum lycopersicum
