In higher plants, the terminal step of L-ascorbic acid (AsA) biosynthesis is catalyzed by the enzyme L-galactono-1,4-lactone dehydrogenase (EC 1.3.2.3, GalLDH). We generated AsA-deficient transgenic tobacco BY-2 cell lines by antisense expression of the GalLDH cDNA that was amplified from

Journal of experimental botany, 62(10), 3647-3657 (2011-03-23)
Ascorbate (AsA) is a redox buffer and enzyme cofactor with various proposed functions in stress responses and growth. The aim was to identify genes whose transcript levels respond to changes in leaf AsA. The AsA-deficient Arabidopsis mutant vtc2-1 was incubated
J Leipner et al.
Planta, 210(6), 964-969 (2000-06-29)
Infiltrating detached maize (Zea mays L.) leaves with L-galactono-1,4-lactone (L-GAL) resulted in a 4-fold increase in the content of leaf ascorbate. Upon exposure to high irradiance (1000 mumol photons m-2 s-1) at 5 degrees C, L-GAL leaves de-epoxidized the xanthophyll-cycle
G L Wheeler et al.
Nature, 393(6683), 365-369 (1998-06-10)
Vitamin C (L-ascorbic acid) has important antioxidant and metabolic functions in both plants and animals, but humans, and a few other animal species, have lost the capacity to synthesize it. Plant-derived ascorbate is thus the major source of vitamin C
Joanna Maddison et al.
Planta, 214(3), 383-391 (2002-02-22)
Leaf L-ascorbate content of an ozone (O3)-sensitive radish genotype (Raphanus sativus L. cv. Cherry Belle) was increased 2-fold by feeding hydroponically cultivated plants L-galactono- 1,4-lactone (GalL). Plants were grown in controlled-environment chambers ventilated with charcoal/Purafil-filtered air, and administered one of
