Photoacclimation and photoinhibition in Ulva rotundata as influenced by nitrogen availability
Clonal tissue of the marine chlorophyte macroalga, Ulva rotundata Blid., was transferred from 100 to 1700 μmol photons · m−2 · s−1 under limiting (1.5 μM NH4+maximum, N/P=2) and sufficient (15 μM… Expand
Relationship between Photosynthesis and Respiration: The Effect of Carbohydrate Status on the Rate of CO(2) Production by Respiration in Darkened and Illuminated Wheat Leaves.
The rate of dark CO(2) efflux from mature wheat (Triticum aestivum cv Gabo) leaves at the end of the night is less than that found after a period of photosynthesis. After photosynthesis, the dark… Expand
Simultaneous measurements of oxygen effects on net photosynthesis and glycolate metabolism in C3 and C4 species of Atriplex
Glycine Decarboxylation in Mitochondria Isolated from Spinach Leaves
Mitochondria isolated from spinach leaves contain at least two glycine decarboxylating systems. One system is stimulated by ADP and evidently couples to the electron transport chain. The other… Expand
Ion Absorption in Atriplex Leaf Tissue II. Secretion of Ions to Epidermal Bladders
The epidermal bladders of several Atriplex species contain high concentrations of ions. Chloride was secreted from the solution or the lamina to the bladders, against a concentration gradient.… Expand

Recent experiments which demonstrate the limited and complementary photosynthetic capacity of mesophyll and bundle sheath chloroplasts in the leaves of C4 plants emphasize the role of structural… Expand
Symplastic Transport of Metabolites During C4-Photosynthesis
The C4 dicarboxylic acid pathway of photosynthetic carbon metabolism is a major elaboration of the photosynthetic carbon reduction cycle (PCR-cycle) which has stimulated a great deal of new research… Expand

Abstract When cultures of the photosynthetic bacterium, Chromatium vinosum , capable of photosynthesizing glycolate at about 10 μmol/mg of bacteriochlorophyll/h were exposed to atmospheres enriched… Expand
Structural Properties and Ribulosebisphosphate Carboxylase and Oxygenase Activity of Fraction-1 Protein from the Marine Alga Halimeda cylindracea (Chlorophyta)
Ribulosebisphosphate carboxylase/oxygenase activity was detected in Halimeda cylindracea and Chaetomorpha crassa. In H. cylindracea carboxylase activity (72-250 micromoles CO2 fixed per hour per… Expand
Localization and properties of ribulose diphosphate carboxylase from castor bean endosperm.
A substantial portion of the ribulose 1,5-diphosphate carboxylase activity in the endosperm of germinating castor beans (Ricinus communis var. Hale) is recovered in the proplastid fraction. The… Expand
