l galactose/oryza sativa

Ascorbic acid (AsA) biosynthesis and its implications for stress tolerance and plant development were investigated in a set of rice knock-out (KO) mutants for AsA biosynthetic genes and their wild-types. KO of two isoforms of GDP-D-mannose epimerase (OsGME) reduced the foliar AsA level by 20-30%,

A biotechnological approach was adopted for increasing foliar ascorbate levels as a strategy to adapt a widely grown high yielding rice variety to multiple abiotic stresses. The variety IR64 (Oryza sativa L. ssp. indica) was engineered to express the ascorbate biosynthesis gene GDP-L-galactose

Effects of zinc (Zn) deficiency on shoot metabolites were investigated in contrasting rice (Oryza sativa L.) genotypes with special focus on ascorbic acid (AsA) biosynthesis, recycling, and catabolism. The genotypes IR74 (sensitive) and RIL46 (tolerant) were subjected to -Zn and control treatments
