As a boy, I read Sinclair Lewis's Arrowsmithand dreamed of doing research of potential benefit to society. I describe the paths of my scientific career that followed. Several distinguished scientists served as my mentors and I present their profiles. Much of my career was in a small department at a small institution where independent researchers collaborated informally. I describe the unique method of carrying on research there. My curiosity about glycolate metabolism led to unraveling the… Expand
Affixing the O to Rubisco: discovering the source of photorespiratory glycolate and its regulation
  • W. Ogren

  • 2004
The source of glycolate in photorespiration and its control, a particularly active and controversial research topic in the 1970s, was resolved in large part by several discoveries and observationsExpand
List of biography and history published mostly in Photosynthesis Research, 1988–2008
As an outgoing Editor of the Historical Corner of Photosynthesis Research, I present here the following list of papers of historical interest for the benefit of all. The first paper I published was:Expand
Why small fluxes matter: the case and approaches for improving measurements of photosynthesis and (photo)respiration.
TLDR
Modified methods are highlighted that are increasingly important when leaves are stressed or when fluxes are inferred at scales larger than the leaf, especially fluxes from photorespiratory CO2, CO2 in the transpiration stream, and through the leaf epidermis and cuticle. Expand
Evidence for a Role for NAD(P)H Dehydrogenase in Concentration of CO2 in the Bundle Sheath Cell of Zea mays1[OPEN]
TLDR
The properties of Zea mays leaves containing Mu and Ds insertions into nuclear gene exons encoding the critical o- and n-subunits of NDH, respectively were examined and photorespiration was generally elevated in maize mutant compared to normal leaves. Expand
High Glycolate Oxidase Activity Is Required for Survival of Maize in Normal Air1[OA]
TLDR
It is shown that C4 photosynthesis in maize is dependent on photorespiration throughout seedling development and support the view that the carbon oxidation pathway evolved to prevent accumulation of toxic glycolate. Expand
Wavelength modulated cavity enhanced absorption spectroscopy of ammonia at 1994 nm
We describe the sensitive detection of ammonia by wavelength modulated cavity enhanced infrared tunable diode laser absorption spectroscopy at 1994 nm. The spectrometer can measure a fractionalExpand

This is about a young man who wished to go to sea like his father and finished up, instead, in photosynthesis. It describes how he served his apprenticeship in England and the United States and howExpand
THE RELATION OF GLYCOLIC ACID SYNTHESIS TO THE PRIMARY PHOTOSYNTHETIC CARBOXYLATION REACTION IN LEAVES.
  • I. Zelitch
  • Biology, Medicine
  • The Journal of biological chemistry
  • 1965
TLDR
Measurements of specific activity provide evidence that glycolic acid is synthesized in the light from COZ by reactions that are largely separate from those of the photosynthetic cycle, especially at concentrations of CO2 close to those normally found in air. Expand
The relationship of glycolic acid to respiration and photosynthesis in tobacco leaves.
  • I. Zelitch
  • Medicine, Chemistry
  • The Journal of biological chemistry
  • 1959
TLDR
It has been concluded that a substantial part of the respiration of mature leaves in sunlight takes place by means of this glycolic acid oxidase. Expand
The role of glycolic acid oxidase in the respiration of leaves.
  • I. Zelitch
  • Biology, Medicine
  • The Journal of biological chemistry
  • 1958
TLDR
It is found that, when excised green leaves are permitted to take up a-hydroxysulfonates by the technique which has been commonly used in biochemical studies in this laboratory, the concentration of glycolic acid rapidly increases to more than 10 times the normal level, suggesting that a large part of the respiration of green leaves in sunlight takes place through gly colic acid oxidase system.

Chance, luck and photosynthesis research: An inside story
A major theme in my career has been photophosphorylation; especially contributions to the early work on chemiosmosis, and later involvement in CF1 activation and function. A second theme has beenExpand
The C4-pathway of photosynthesis. Evidence for an intermediate pool of carbon dioxide and the identity of the donor C4-dicarboxylic acid
TLDR
The kinetics of labelling of the major CO(2) pool and of depletion of label during a ;chase' was consistent with this pool being derived from the C-4 of malate and being the precursor of theC-1 of 3-phosphoglycerate. Expand
The effect of glycidate, an inhibitor of glycolate synthesis, on photorespiration and net photosynthesis.
  • I. Zelitch
  • Biology, Medicine
  • Archives of biochemistry and biophysics
  • 1974
TLDR
The demonstration of increases in net photosynthesis of 40–50% when glycolate synthesis (and photorespiration) is blocked with glycidate indicates in an independent manner that the biochemical or genetic control of photOREspiration should permit large increases in plant productivity in plant species possessing rapid rates of photoreSpiration. Expand
Increased rate of net photosynthetic carbon dioxide uptake caused by the inhibition of glycolate oxidase.
TLDR
The use of an inhibitor of the oxidation of glycolate, the substrate for photorespiration, changed tobacco so that it behaved photosynthetically like maize, and may limit the net CO(2) uptake in many plant species. Expand
The C 4 -pathway of photosynthesis. Evidence for an intermediate pool of carbon dioxide and the identity of the donor C 4 -dicarboxylic acid.
  • M. Hatch
  • Medicine
  • The Biochemical journal
  • 1971
TLDR
The kinetics of labelling of the major CO(2) pool and of depletion of label during a ;chase' was consistent with this pool being derived from the C-4 of malate and being the precursor of the C of 3-phosphoglycerate. Expand
Questions about the complexity of chloroplast ribulose-1,5-bisphosphate carboxylase/oxygenase
TLDR
The complexity of chloroplast Rubisco in land plants cannot be completely addressed with the existing model organisms, and attempts to engineer or discover a better Rubisco may be futile if one cannot transfer the better enzyme to a compatible host. Expand
