Figure 11
Changes in gene expression in the photorespiratory cycle of the glu1-2 mutant leaves. Schematic representation of the photorespiratory cycle and indication of the genes that show different expression levels in glu1-2 leaves compared to wild-type leaves. Gene IDs indicated in blue are upregulated whereas those indicated in red are downregulated in the glu1-2 mutant. Genes involved in the Calvin cycle have been omitted from this figure (see Figure 10 for this purpose). Enzymes: (1) ribulose-1,5-biphosphate carboxylase/oxygenase, (2) phosphoglycolate phosphatase, (3) glycolate oxidase, (4) glutamate:glyoxylate aminotransferase, (5) glycine decarboxylase complex, (6) serine hydroxymethyltransferase, (7) serine:glyoxylate aminotransferase, (8) hydroxypyruvate reductase, (9) glycerate kinase, (10) mitochondrial malate dehydrogenase, (11) peroxisomal malate dehydrogenase, (12) glutamine synthetase 2, (14 and 15) chloroplast dicarboxylate transporter 1 and 2, (16) mitochondrial dicarboxylate carriers. Black boxes indicate putative transporters. The detailed data of the genes depicted in this figure and the affected genes in glu1-2 roots are presented in Table 4. Abbreviations used: OAA: oxaloacetate; RuBP: ribulose-1,5-biphosphate; THF: tetradydrofolate.
