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

Free radical biology & medicine, 28(2), 183-192 (2001-04-03)
This study investigated the ability of the yeast Saccharomyces cerevisiae to synthesize ascorbate and its 5-carbon analogue erythroascorbate from a variety of precursors, and their importance as antioxidants in this organism. Studies of ascorbate and analogues in micro-organisms have been
