Integration of Photosynthetic Carbon Metabolism During Stress

  • C. B. Osmond
Part of the Basic Life Sciences book series (BLSC, volume 14)

Abstract

By and large, studies of photosynthesis in response to stress have pursued the reductionist philosophies of biochemistry and biophysics, and have not sought to provide integrated accounts of photosynthetic processes in successful wild plants or among the successful products of pragmatic plant breeding. Integration of biochemical, physiological and ecological aspects of photosynthesis is essential if we are to further improve upon these successful experiments. Natural selection, which is responsible for the successful plants now found in what we regard as stress environments, acts not on isolated components (such as osmoregulation) which may respond to random mutations, but upon whole integrated physiological processes which are products of the total genetic potential of the organism. Waddington (1972) reminds us that “it remains true enough to say the ultimate units, the pebbles in the concrete or genes in the organism, have been produced by random processes, (but) this is almost irrelevant to the engineering of a bridge and, in many cases, not much more relevant to the anatomical or physiological construction of the organism.”
