    Notes: Low temperatures are known to restrict chloroplast development and prevent the attainment of photosynthetic competence in maize leaves. The responses of the photosynthetic apparatus of mature maize leaves grown at 14°C on transfer of the plants to 25°C are examined. The synthesis of thylakoid proteins increased immediately on transfer of leaves from 14 to 25°C, with a dramatic accumulation of thylakoid proteins and chlorophylls occurring after 3 d at 25°C. Thylakoid structure and organization also became similar to those observed in leaves grown at 25°C over this period. However, no comparable development of photosynthetic competence in photosystems I and II or in the rate of CO2 assimilation was observed on transfer of leaves from 14 to 25°C. Immunocytological analyses demonstrated heterogeneity in the distribution of a range of thylakoid proteins (cy tochrome f, the α and β subunits of the coupling factor, Dl of the photosytem II reaction centre, the 33kDa protein of the extrinsic oxygen-evolving complex of photosystem II, and subunit II of photosystem I between mesophyll cells in leaves grown at 14°C, and in the responses of individual proteins to transfer of the leaves to 25°C. Such heterogeneity between mcsophyll cells would account for the inability of the leaves to develop the expected degree of photosynthetic competence on transfer to 25°C. The effects of low growth temperatures on chloroplast biogenesis are complex, as are the changes induced by the transfer ofleaves grown at low temperatures to optimal growth temperature, and both these factors may limit the canopy development and photosynthetic productivity of crops in temperate regions.

    The antioxidant effects of thylakoid Vitamin E (α-tocopherol) (1992)
    Oxford, UK : Blackwell Publishing Ltd
    Plant, cell & environment 15 (1992), S. 0

    Topics: Biology
    Notes: Vitamin E (α-tocopherol) is essential for the prevention of photo-oxidative deterioration of biomembranes. The occurrence, relative biological activity and distribution of tocopherols in photosynthetic membranes is considered together with the possible biochemical and biophysical mechanisms by which tocopherols confer protection upon illuminated membranes. The common protective effects of Vitamin E in photo-synthetic membranes and in medically important light-induced diseases and conditions of the skin and eye in animal cell membranes are discussed. The importance of the Vitamin E-Vitamin C thylakoid antioxidant system is also examined, in terms of susceptibility to photo-oxidative damage under stress conditions including chilling, ageing and senescence, drought, atmospheric pollutants, herbicides and photosensitizing fungal toxins.

    Paralysis of skeletal muscle by butanedione monoxime, a chemical phosphatase (1988)

    Notes: Abstract The chemical phosphatase butanedione monoxime (BDM) reversibly inhibited twitches and tetanic contractions in bundles of rat soleus fibres in a dose-dependent manner (2–20 mM) but had no effect on the amplitude or time course of action potentials. In addition, BDM reversibly reduced the amplitude of potassium contractures demonstrating a depressant effect on contraction not mediated by action potentials. BDM had no effect on asymmetric charge movement but depressed calcium currents across the surface membrane in voltage-clamped fibres. The most significant effect of BDM on excitation-contraction coupling was a reduction in the amplitude of the calcium transient associated with contraction in aequorin-injected fibres. While these experiments do not eliminate the possibility of a direct effect of BDM on contractile filaments, reduction of calcium release from the sarcoplasmic reticulum, at least at low concentrations of BDM (below 2 mM), would seem to be the main mechanism for the inhibition of contractions in rat skeletal muscle.
