The present work reports changes in bioenergetic parameters and mitochondrial activities during the manifestation of two events of programmed cell death (PCD), linked to Abies alba somatic embryogenesis. PCD, evidenced by in situ nuclear DNA fragmentation (TUNEL assay), DNA laddering and cytochrome c release, was decreased in maturing embryogenic tissue with respect to the proliferation stage. In...
This report demonstrates that mitochondria isolated from thermogenic Arum spadices possess an ATP-sensitive potassium channel – responsible for electrical potential (ΔΨ) collapse and mitochondrial swelling – whose characteristics are similar to those previously described in pea and wheat mitochondria. In order to study the relationship between this KATP+ channel and the uncoupled respiration, linked...
The roles of mild uncoupling caused by free fatty acids (mediated by plant uncoupling mitochondrial protein (PUMP) and ATP/ADP carrier (AAC)) and non-coupled respiration (alternative oxidase (AO)) on H 2 O 2 formation by plant mitochondria were examined. Both laurate and oleate prevent H 2 O 2 formation dependent on the oxidation of succinate. Conversely, these free...
