Lack of embryonic axis control in Pisum cotyledon mitochondria

Respiratory control ratio (RCR), ADP: O and oxygen uptake by isolated mitochondria from cotyledons of the genus Pisum were studied. It is shown that in P. sativum the embryonic axis has a slight effect on the behaviour of the mitochondria in the cotyledons, accelerating their degeneration. The induc...

Summary:Respiratory control ratio (RCR), ADP: O and oxygen uptake by isolated mitochondria from cotyledons of the genus Pisum were studied. It is shown that in P. sativum the embryonic axis has a slight effect on the behaviour of the mitochondria in the cotyledons, accelerating their degeneration. The inducing factor is transferred within 1 hr from the onset of imbibition from the axis to the cotyledon. In P. elatius the embryonic axis completely lacked an effect on the mitochondria in the cotyledons. Mitochondria in P. elatius seemed to be highly organized and not leaky.
