Changes in gene expression in chlorophyll biosynthesis of the glu1-2 mutant leaves. Schematic representation of chlorophyll biosynthesis and the genes showing different expression levels in glu1-2 leaves. Gene IDs indicated in blue are upregulated whereas those indicated in red are downregulated. Enzymes: (1) glutamate-tRNA ligase, (2) glutamyl-tRNA reductase, (3) glutamate-1-semialdehyde 2,1-aminomutase, (4) porphobilinogen synthase, (5) hydroxymethylbilane synthase, (6) uroporphyrinogen-III synthase, (7) uroporphyrinogen decarboxylase, (8) coproporphyrinogen oxidase, (9) protoporphyrinogen oxidase, (10) magnesium chelatase, (11) magnesium protoporphyrin IX methyltransferase, (12) magnesium protoporphyrin IX monomethyl ester cyclase, (13) 3,8-divinyl protochlorophyllide 8-vinyl reductase, (14) protochlorophyllide oxidoreductase, (15) chlorophyll synthase, (16) geranylgeranyl reductase, (17) chlorophyllide a oxygenase, (18) chlorophyllide b reductase, (19) 7-hydroxy chlorophyllide a reductase, (20) ferrochelatase. Reduced acceptors and cofactors are omitted from the figure. The detailed data of the genes depicted in this figure and the affected genes in glu1-2 roots are presented in Additional file 6.
