Impact of MDH loss on respiratory rate of leaves and roots. A, Respiratory CO₂ production of lighted leaves in gas phase measured by the method of Laisk. Bars are means ± sd (n > 3), and asterisks indicate significant differences (P < 0.05) from the wild type (Wt). B, CO₂ production in darkened leaves in gas phase. Bars are means ± sd (n > 3), and asterisks indicate significant differences (P < 0.05) from the wild type. C, Root respiration as oxygen consumption rate in liquid phase. Bars are means ± se (n = 3). FW, Fresh weight. Plants were grown under short-day conditions.
