“…Previous data (Thoiron et al 1974) had already shown that the driving force term, log :;r. was very little modified during the process of recovery from the shock, while the conductance term. L. was very different at the beginning of recovery and after full recovery.…”

“…who have shown that an increased membranebound triphosphatase activity accompanies development of enhanced solute uptake in washed corn root tissue. However, if the effect of gas-shock was only on the proton pump, which energizes transport of the different substrates considered here, one would expect that the "driving force" parameter, log 7t:, of our thermodynamical analysis should change greatly during recovery; but we have seen that this is not the case (for more details, see Thoiron et al 1974). An alternative explanation would then be that gas-shock influences the periplasmic proteins participating in the absorption sys- Figure 1.…”

The resumption of solute uptake capacity lost after gas‐shock of Acer pseudoplatanus L. cell suspension cultures is severely inhibited by low temperatures (1°C) and by inhibitors of transcription and translation of protein synthesis such as 2‐mercapto‐1 (β‐4‐pyridethyl) benzimidazole (MPB, 40 μg ml−1), puromycin (around 100 μg ml−1) and actinomycin (100 μg ml−1). Cells that have already attained maximum uptake capacity loose it again after less than 1 h in 40 μg ml−1 MPB. Gel‐electrophoresis of the external media of the cells shows that the release of proteins into the solution is affected by shock. The results demonstrate that proteins are involved in the mechanism of solute uptake by the cells, so that these proteins are among the factors altered during shock and recovery, and are important for the understanding of the after‐effects of shock.

“…Ammonium uptake by the latter system appears to be membrane potential-driven rather than H + -coupled (Ludewig et al 2002). Thoiron et al (1974) studied the sulphate permeability of Acer pseudoplatanus cell suspension culture. Simonis et al (1974) and Jeanjean and Ducet (1974) examined phosphate uptake in Anacystis nidulans and Chlorella pyrenoidosa, respectively.…”

In the past 30 years enormous progress was made in plant membrane biology and transport physiology, a fact reflected in the appearance of textbooks. The first book dedicated to 'Membrane Transport in Plants' was published on the occasion of the 'International Workshop on Membrane Transport in Plants' held at the Nuclear Research Center, Jülich, Germany [Zimmermann and Dainty (eds) 1974] and was followed in 1976 by a related volume 'Transport in plants II' in the 'Encyclopedia of plant physiology' [Lüttge and Pitman (eds) 1976]. A broad spectrum of topics including thermodynamics of transport processes, water relations, primary reactions of photosynthesis, as well as more conventional aspects of membrane transport was presented. The aim of the editors of the first book was to bring advanced thermodynamical concepts to the attention of biologists and to show physical chemists and biophysicist what the more complex biological systems were like. To bundle known data on membrane transport in plants and relevant fields for mutual understanding, interdisciplinary research and clarification of problems were considered highly important for further progress in this scientific area of plant physiology. The present review will critically evaluate the progress in research in membrane transport in plants that was achieved during the past. How did 'Membrane Transport in Plants' progress within the 30 years between the publication of the first book about this topic (Zimmermann and Dainty 1974), a recent one with the same title (Blatt 2004), and today?
