Background As universal energy currency, intracellular ATP (iATP) shortages in horticultural
crops during postharvest stresses and senescence. In addition to function as intracellular …

Mitochondria are a quantitatively relevant source of reactive oxygen species (ROS) in the
majority of cell types. Here we review the sources and metabolism of ROS in this organelle …

Mitochondrially generated reactive oxygen species are involved in a myriad of signaling and
damaging pathways in different tissues. In addition, mitochondria are an important target of …

The concept of hormesis in plants is critically reviewed, taking growth stimulation by low
concentrations of toxic trace elements as a reference. The importance of both non-adaptive …

Significance: The concept that vitamin C (l-ascorbic acid) is at the heart of the peroxide
processing and redox signaling hub in plants is well established, but our knowledge of the …

Plants are sessile organisms that often receive excessive amounts of light energy. This
excess energy can be exported from the chloroplasts and dissipated by the mitochondrial …

Plant mitochondria differ from their mammalian counterparts in many respects, which are
due to the unique and variable surroundings of plant mitochondria. In green leaves, plant …

Significance: Mitochondria are the energetic, metabolic, redox, and information signaling
centers of the cell. Substrate pressure, mitochondrial network dynamics, and cristae …

The electron transport chain in mitochondria of different organisms contains a mixture of
common and specialised components. The specialised enzymes form branches to the …

A general status of oxidative stress in plants caused by exposure to elevated metal
concentrations in the environment coincides with a constraint on mitochondrial electron …
