2.7.1.182 additional information generation of an RNAi line (vte5) from cv. Micro-Tom with a downregulation of 76% in under control conditions and reduced levels of alpha-tocopherol. Mutant vte5 has plastoquinone levels similar to those of the wild-type under combined stress, the strong phenotype can be attributed to the lack of alpha-tocopherol. Mutant vte5 plants accumulate free phytol in the leaf. Phenotype, overview Solanum lycopersicum

General Information

EC Number General Information Comment Organism
2.7.1.182 malfunction silenced mutant vte5 suffers strong photoinhibition and photobleaching when exposed to combined high-light and high-temperature stress, but neither stress alone produces a visible phenotype. Mutant vte5 has plastoquinone levels similar to those of the wild-type under combined stress, the strong phenotype can be attributed to the lack of alpha-tocopherol. Mutant vte5 plants accumulate free phytol in the leaf Solanum lycopersicum
2.7.1.182 physiological function essential role for phytol kinase and tocopherol in tolerance to combined light and temperature stress in tomato. Phytol kinase VTE5 acts in the biosynthetic pathway of tocopherols. VTE5 protects against combined high-light and high-temperature stress and does so by supporting alpha-tocopherol production Solanum lycopersicum
