To clarify the involvement of seven Arabidopsis homologs of rat L-gulono-1,4-lactone (L-GulL) oxidase, AtGulLOs, in the biosynthesis of L-ascorbic acid (AsA), transgenic tobacco cells overexpressing the various AtGulLOs were generated. Under treatment with L-GulL, the levels of total AsA in three transgenic tobacco cell lines, overexpressing AtGulLO2, 3, or 5, were significantly increased as compared with those in control cells.
