The enormous scope of the subject matter encompassed in the title
demands a departure from the usual form of review. Instead of a meticulous compilation of the recent pertinent literature, a current concept of
the regulation of the rate of respiration and of energy coupling in
metabolism will be presented, and a select, but it is hoped, representative body of plant physiological data will be evaluated within the framework of that concept.
This being the first treatment of the present topic predominantly plant
physiological in purview, the choice of papers will not be limited to
current material, although so much as is pertinent will be emphasized in
each section. Some of the work to be discussed has been previously reviewed in other contexts, but it is felt that the purpose served by bringing together a wide variety of observations within the framework of a
unifying interpretation may justify their reappraisal. Particular attention will be given those experimental objects—Avena coleoptiles, pea
sections, roots of the Gramineae, disks of storage organs—which have in
