1.3.2.3 additional information homozygous Arabidopsis thaliana mutant (gldhRNAi3-11) plants with approximately 40% of the GLDH activity of wild-type controls are developed by RNA interference (three genotypes), and are viable under standard laboratory conditions. Mutant gldhRNAi3-11 plants show about 20% decrease in the contents of reduced ascorbic acid and total ascorbic acid.
