2.7.9.1	malfunction	the maize transposable elements Mutator and Ds are used to generate multiple mutant alleles of pyruvate orthophosphate dikinase (PPDK). Loss-of-function mutants are seedling lethal, even when plants are grown under 2% CO2, and they show very low capacity for CO2 assimilation, indicating C4 photosynthesis is essential in maize. Loss of PPDK results in downregulation of gene expression of enzymes of theC4 cycle, the Calvin cycle, and components of photochemistry. The loss of PPDK does not change Kranz anatomy, indicating that this metabolic defect in the C4 cycle does not impinge on the morphological differentiation of C4 characters. However, sugar metabolism and nitrogen utilization are altered in the mutants	Zea mays
