    Volatilization of Mercury by Algae (1975)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 33 (1975), S. 0 
    Details
    ISSN: 1399-3054
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: The presence of Chlorella cells in a medium containing HgCl2 causes a rapid decrease of the mercury content in the algal suspension. The rate of decrease depends on the inoculum concentration. The presence of Hg in the medium induces a lag in the growth, whose length depends on the initial concentration of Hg and of the inoculum. Binding and/or uptake of mercury by the cells is not dependent on temperature. The mercury content per cell declines somewhat at the time at which the culture resumes growth at a rate similar to that of the controls without mercury.

    Germination, Utilization of Storage Materials and Potential for Cyanide Release in Cultivated and Wild Sorghum (1979)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 47 (1979), S. 0 
    Details
    ISSN: 1399-3054
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Sorghum halepense germinates only after storage and its germination is impeded by its glumes. On germination its metabolism is more rapid than is S. bicolor, as indicated by loss of dry weight, starch and protein and formation of soluble protein and soluble sugars. Fresh weight formation is also more rapid in S. halepense. A method for determining the potential for cyanide liberation is described. S. halepense builds up the potential rapidly and apparently maintains it after germination. This process is also slower in S. bicolor. The results show that the cultivated species is slower in all the processes leading to germination than the wild one.

    Light-Induced Hg Volatilization and O2 Evolution in Chlorella and the Effect of DCMU and Methylamine (1978)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 42 (1978), S. 0 
    Details
    ISSN: 1399-3054
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: The rate of volatilization of Hg2+ as metallic Hg is accelerated by illumination of Chlorella cells. In the presence of the uncoupler methylamine the rate of volatilization in the light is greatly but transiently increased. DCMU (3-(3,4-dichlorophenyl)-1,1-dimethyl urea) prevented the light response. In the presence of Hg2+, O2 evolution by the cells was not completely inhibited by DCMU. Hg2+ appears to prevent DCMU reaching its binding site. Light seems to increase the amount of or leakage from the cells of a metabolite capable of reducing Hg2+ to Hg°.

    Respiration and Utilization of Storage Materials in Wild and Cultivated Pea Seeds during Germination (1976)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 38 (1976), S. 0 
    Details
    ISSN: 1399-3054

    Topics: Biology
    Notes: Breakdown of storage materials, oxygen uptake, respiratory control and ADP/O ratios in the cotyledons of the garden pea P. sativum and in the wild pea P. elatius were compared. Starch and protein degradation was slower in P. elatius than in P. sativum. Embryo growth began later in the wild pea. However, in the garden pea the mitochondria were uncoupled after about 48 h of germination, while in P. elatius the ability to carry out oxidative phosphorylation was maintained for 4 days. The respiratory control ratio was higher in the wild pea at all stages of germination and a steady level of oxygen uptake was maintained in the cotyledons for at least 3 days.The findings are discussed in relation to the ecological requirements for germination in the two species.

    Reduction of Mercury Chloride by Chlorella: Evidence for a Reducing Factor (1977)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 40 (1977), S. 0 
    Details
    ISSN: 1399-3054
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Evidence is brought for the presence of low molecular weight, heat stable, mercury reducing factors in Chlorella cells. Some of the properties of these factors, which appears to be normal metabolities, are described. These factors are also present in the medium in which the cells grow. The reduced mercury, Hg0, is volatilized from the culture medium more rapidly than Hg+2. The resultant decrease in the Hg concentration appears to be the main reason for the recovery of the cells from Hg stress. No resistance to Hg developed in cells emerging from the stress.

    Nitrite activation of nitrate reductase in higher plants (1978)
    Springer
    Planta 138 (1978), S. 205-209

    ISSN: 1432-2048
    Keywords: Hordeum Nitrite ; Nitrate reductase

    Topics: Biology
    Notes: Abstract Comparative studies of nitrate-activated nitrate reductase (NR-NO2) and nitrate-induced nitrate reductase (NR-NO3) (EC 1.6.6.2) indicate that the enzymes differ in structure, heat stability, and pH dependence, but have the same cofactor requirment. NR-NO2 developes in barley (Hordeum vulgare L. var. Dvir) seedlings as NR-NO3 disappears. A transition from the active to the inactive form of nitrate reductase takes place. Nitrite seems to activate the inactive form of the enzyme.
