Alteration of the respiration rate of WT and dek47-1.

	Respiration rate (nmol O2 min−1 g−1 fresh weight)
	Vt	Valt	Vcyt	Valt/Vt(%)	Vcyt/Vt(%)
WT	829.88 ± 70.25	196.46 ± 20.09	700.63 ± 67.55	16.69	84.32
dek47-1	102.56 ± 14.29***	56.23 ± 9.56*	48.60 ± 1.40***	62.20*	55.68**

Mitochondrial total respiration rate (V_t), the capacity of the cytochrome pathway (V_cyt), and the alternative pathway (V_alt) were indicated by O₂ consumption of the fresh maize kernels at 11 DAP. Data are mean values ± SEs from three independent biological samples. Asterisks indicate significant differences between means calculated with Student’s t-test.
