Figure 4From: Phosphate starvation of maize inhibits lateral root formation and alters gene expression in the lateral root primordium zoneModulation of genes encoding enzymes involved in auxin metabolism in response to low phosphate stress. Differentially modulated genes are indicated with an arrowhead. Biochemical and physiological pathways were classified according to the KEGG database (http://www.genome.jp/kegg/). aroK: shikimate kinase; aroA: 3-phosphoshikimate 1-carboxyvinyltransferase; aroC: chorismate synthase; TRP: anthranilate synthase/indole-3-glycerol phosphate synthase; trpD: anthranilate phosphoribosyltransferase; TRP1: anthranilate synthase/indole-3-glycerol phosphate synthase/phosphoribosylanthranilate isomerase; TRP3: anthranilate synthase/indole-3-glycerol phosphate synthase; trpA: tryptophan synthase alpha chain.Back to article page
