Exposure of six day old rice (Oryza sativa) seedlings to salt or cadmium stress lead to an increase in the level of proline with a simultaneous decline in the mitochondrial electron transport activity. Mitochondrial electron transport inhibitors - rotenone, antimycin A or potassium cyanide also
Mitochondria isolated from the roots of barley (Hordeum vulgare L.) and rice (Oryza sativa L.) seedlings were capable of oxidizing external NADH and NADPH anaerobically in the presence of nitrite. The reaction was linked to ATP synthesis and nitric oxide (NO) was a measurable product. The rates of
