General Information | Comment | Organism |
---|---|---|
physiological function | an Arabidopsis thalina that accumulates tocotrienols and homogentisate by co-expression of Arabidopsis thaliana hydroxyphenylpyruvate dioxygenase and Escherichia coli bi-functional chorismate mutase/prephenate dehydrogenase loses tocotrienol production when crossed into the vte2-1 HPT null mutant. Hydroxyphenylpyruvate dioxygenase/TyrA-induced tocotrienol production requires HPT and occurs upon enrichment of geranylgeranyl diphosphaterelative to phytyl diphosphate in prenyl diphosphate pools | Arabidopsis thaliana |
