Changes in Mitochondrial Properties Associated with Chloroplast Development in Jack Bean (Canavalia ensiformis [L] DC.) 1

AUTOR(ES)
RESUMO

Procedures were developed to isolate actively respiring mitochondria from jack bean (Canavalia ensiformis [L.] DC.) leaves and cotyledons. Consistent respiratory control values of about 2 for succinate oxidation were obtained in preparations from etiolated cotyledons. Jack bean mitochondria oxidized malate with high respiratory control (2 to 5) and ADP/O (up to 2.8).
