Changes in oxygen uptake of mitochondria from susceptible and resistant tomato roots infested by Meloidogyne incognita
AbstractMitochondria were isolated from susceptible and resistant tomato roots uninfested and infested by Meloidogyne incognita. Oxygen uptake of infested mitochondria was lower in resistant and higher in susceptible cultivar compared with that of uninfested mitochondria. Duroquinol, NADH, malate and succinate were used as oxidable substrates. Changes in alternative pathway respiration were also detected.
