Abstract excerpt
Arabidopsis thaliana contains two GDP-L-galactose phosphorylase genes, VTC2 and VTC5, which are critical for ascorbate (AsA) biosynthesis. We investigated the expression levels of both VTC2 and VTC5 genes in wild-type A. thaliana and the AsA deficient mutants during early seedling growth. Ascorbate accumulated to an equal extent in all genotypes up to 5 d post-germination (DPG). The transcript level of VTC2 was...
