L-Ascorbic acid and L-galactose are sources for oxalic acid and calcium oxalate in Pistia stratiotes
TLDR
Results demonstrate a biosynthetic role for AsA as precursor of OxA and its crystalline deposition product, CaOx, in idioblast cells of P. stratiotes and support the recent discovery of Wheeler, Jones and Smirnoff that L-galactose is a key intermediate in the conversion of D-glucose to AsA in plants.About:

CALCIUM OXALATE IN PLANTS: Formation and Function
TL;DR: Using a variety of approaches, researchers have begun to unravel the exquisite control mechanisms exerted by cells specialized for CaOx formation that include the machinery for uptake and accumulation of Ca, oxalic acid biosynthetic pathways, and regulation of crystal growth.
Journal ArticleDOI
Ascorbic acid in plants: biosynthesis and function.
TL;DR: Ascorbate-deficient vtc 1 mutants of Arabidopsis thaliana have been found to have a higher susceptibility to ozone and UV-B radiation, and the rapid response of ascorbates peroxidase expression to (photo)-oxidative stress.
Journal ArticleDOI
BIOSYNTHESIS OF ASCORBIC ACID IN PLANTS: A Renaissance.
TL;DR: The description in 1996 of an Arabidopsis thaliana mutant deficient in ascorbic acid prompted renewed research effort in this area, and subsequently in 1998 a new pathway was discovered that is backed by strong biochemical and molecular genetic evidence.
Journal ArticleDOI
Advances in our understanding of calcium oxalate crystal formation and function in plants
TL;DR: A number of mutants defective in different aspects of calcium oxalate crystal formation have been isolated Cellular and biochemical characterizations of the various mutants have revealed mutations affecting crystal nucleation, morphology, distribution, and/or amount such mutants will be useful tools in continued efforts to decipher the pathways of crystal formation and function in plants.
Journal ArticleDOI
Ascorbic acid metabolism and functions: A comparison of plants and mammals
TL;DR: Ascorbate status influences gene expression in plants and mammals but at present there is little evidence that it acts as a specific signalling molecule and the possibility that dehydroascorbylation is a regulatory post‐translational protein modification could be explored.

The biosynthetic pathway of vitamin C in higher plants
TL;DR: The definition of this biosynthetic pathway should allow engineering of plants for increased ascorbate production, thus increasing their nutritional value and stress tolerance.
Journal ArticleDOI
Calcium oxalate crystals in plants
TL;DR: The purpose of this review is to present an overview of plant crystal idioblasts and Ca oxalate crystals and to include the most recent literature.
Book
Oxalic acid in biology and medicine
TL;DR: The author’s intention is clearly to bring together the many wide-spread aspects of past and present research on oxalic acid and he succeeds in doing so while giving an interesting and readable account of the subject.
Journal ArticleDOI
Genetic evidence for the role of GDP-mannose in plant ascorbic acid (vitamin C) biosynthesis.
TL;DR: By using a combination of biochemical, molecular, and genetic techniques, it is demonstrated that the VTC1 locus encodes a GDP-mannose pyrophosphorylase (mannose-1-P guanyltransferase).
Journal ArticleDOI
Biosynthesis and metabolism of ascorbic acid in plants and of analogs of ascorbic acid in fungi
TL;DR: An attempt is made to draw attention to l -ascorbic acid biosynthesis and metabolism in plants and to structurally similar compounds in fungi.
