physiological function | double mutants lacking both plastidial isoforms gapcp1 and gapcp2 display a drastic phenotype of arrested root development, dwarfism, and sterility. In spite of their low gene expression level, GAPCp down-regulation leads to altered gene expression and to drastic changes in the sugar and amino acid balance of the plant. GAPCps are important for the synthesis of serine in roots. Serine supplementation to the growth medium rescues root developmental arrest and restores normal levels of carbohydrates and sugar biosynthetic activities in gapcp double mutants | Arabidopsis thaliana |
