Plant bioenergetics

Ozone has been shown to initiate many physiological and biochemical changes in sensitive plant species. Decreases in photosynthesis and increases and decreases in respiration have occurred in response to ozonation. The bioenergetic status of mitochondria and chloroplasts is disturbed by ozone. Decreases in oxidative- and photo- phosphorylation have been reported as have increases in adenosine triphosphate and total adenylate content of plant tissue. The variable physiological responses appear to be related to the stage of symptom development at the time of analysis and to the mode of ozone exposure, viz. in vivo and in vitro.

The occurrence, translocation, anabolism, and catabolism of carbohydrates related to the bioenergetics of plants have been reviewed (141). The energy sources stored for growth in living cells within woody tissue include mono- and oligosaccharides. The mono- and oligosaccharides are usually determined together in saps and in extracts of various tissues. They are most often extracted with hot 80% ethanol 75% methanol, water, aqueous acetone, and other concentrations of ethanol have also been used.
