    Abstract Hikers passing through nature easily recognize that the vegetation on limestone (calcareous soils) and silicate (acidic soils) is very different. This is not so much the case with trees but with herbs, particularly in grasslands. These differences in the vegetation on both soil types, referred to as the lime–silicate question, were recognized as early as the 18th century. Even so, fairly little is known about why this occurs. The current paucity of information exists mainly because the determinants that govern the formation of plant communities on either lime or acid soils mainly reside below-ground, in the root-surface area, and these complex below-ground interactions are almost impossible to explore through experimental approaches and direct measurements. Element availability or toxicity and interactions with microorganisms are both equally important. The calcium cation, for example, is not only an essential growth component but can be severely toxic to plants in unbalanced concentrations. Plants also vary in their ability to acquire iron and phosphorus. Aluminium toxicity affects plant growth, particularly in acid soils, and acid-tolerant plants have acquired the capability to cope with high levels of Al in soils. Mainly saprophytic fungi serve to degrade litter in acid soils and liberate nutrients for plant growth. In calcareous soils, bacteria and small animals, such as earthworms and their inhabitant bacteria, are the main decomposers of litter and contribute significantly to the fertility of the soils. Arbuscular mycorrhizal fungi (AMF) have a particularly significant role in calcareous soils, where they are believed to determine the competitiveness of plants in lime meadows. Physical factors also impact the different composition of plant communities in acid and calcareous soils.

    Abstract The properties of the ferredoxin-catalysed cyclic photophosphorylation in lyophilised and lysozyme treated Anacystis nidulans with rates up to 80 μmoles ATP/h/mg chlorophyll are described. The concentration of ferredoxin needed for the saturation of the ferredoxin-catalysed cyclic photophosphorylation is about 6 — 8 times higher than for NADP-reduction. In contrast to the ferredoxin-catalysed cyclic photophosphorylation in spinach chloroplasts the reaction in Anacystis is relatively intensive to the “poising“ of the system and is not affected by antimycin A. Whilst under aerobic conditions in broken chloroplasts ferredoxin catalyses a pseudocyclic photophosphorylation in which H₂O₂ is a component, in Anacystis on addition of ferredoxin ATP is only formed on the cyclic pathway even in air. In chloroplasts as well as in Anacystis disulfo-disalicylidenpropandiamin (DSPD) inhibits only the ferredoxin-catalysed cyclic photophosphorylations and the NADP-reductions, but not the ferredoxin stimulated ATP-formations under aerobic conditions. Evidence is presented once more that ferredoxin is the cofactor of cyclic photophosphorylation in vivo.

    Abstract Among heavy metal plants (the metallophytes), facultative species can live both in soils contaminated by an excess of heavy metals and in non-affected sites. In contrast, obligate metallophytes are restricted to polluted areas. Metallophytes offer a fascinating biology, due to the fact that species have developed different strategies to cope with the adverse conditions of heavy metal soils. The literature distinguishes between hyperaccumulating, accumulating, tolerant and excluding metallophytes, but the borderline between these categories is blurred. Due to the fact that heavy metal soils are dry, nutrient limited and are not uniform but have a patchy distribution in many instances, drought-tolerant or low nutrient demanding species are often regarded as metallophytes in the literature. In only a few cases, the concentrations of heavy metals in soils are so toxic that only a few specifically adapted plants, the genuine metallophytes, can cope with these adverse soil conditions. Current molecular biological studies focus on the genetically amenable and hyperaccumulating Arabidopsis halleri and Noccaea (Thlaspi) caerulescens of the Brassicaceae. Armeria maritima ssp. halleri utilizes glands for the excretion of heavy metals and is, therefore, a heavy metal excluder. The two endemic zinc violets of Western Europe, Viola lutea ssp. calaminaria of the Aachen-Liège area and Viola lutea ssp. westfalica of the Pb-Cu-ditch of Blankenrode, Eastern Westphalia, as well as Viola tricolor ecotypes of Eastern Europe, keep their cells free of excess heavy metals by arbuscular mycorrhizal fungi which bind heavy metals. The Caryophyllaceae, Silene vulgaris f. humilis and Minuartia verna, apparently discard leaves when overloaded with heavy metals. All Central European metallophytes have close relatives that grow in areas outside of heavy metal soils, mainly in the Alps, and have, therefore, been considered as relicts of the glacial epoch in the past. However, the current literature favours the idea that hyperaccumulation of heavy metals serves plants as deterrent against attack by feeding animals (termed elemental defense hypothesis). The capability to hyperaccumulate heavy metals in A. halleri and N. caerulescens is achieved by duplications and alterations of the cis-regulatory properties of genes coding for heavy metal transporting/excreting proteins. Several metallophytes have developed ecotypes with a varying content of such heavy metal transporters as an adaption to the specific toxicity of a heavy metal site.
