TL;DR: Experiments are described which show that lead becomes bound strongly to certain chemical substances involved in cell wall architecture, which appears to be linked with changes in the properties of the cell walls.
Abstract: In vitro studies of IAA-induced cell elongation in Triticum aestivum have demonstrated that lead causes a large reduction in elongation. Inhibition of elongation can be reduced by increasing the concentration of IAA, or by the addition of calcium. The inhibitory effect appears to be linked with changes in the properties of the cell walls. Experiments are described which show that lead becomes bound strongly to certain chemical substances involved in cell wall architecture.

TL;DR: The culture extracts of 21 micro-organisms were screened in vitro for anti-microbial activity against a range of test contaminants isolated from plant tissue cultures and extracts from Pseudomonas fluorescens Migula had the highest antibacterial activity.
Abstract: The culture extracts of 21 micro-organisms were screened in vitro for anti-microbial activity against a range of test contaminants isolated from plant tissue cultures. Extracts produced by Trichoderma viride Pers. (strain A) and Bacillus subtilis Ehrenberg (strain 2) had the highest antifungal activity and extracts from Pseudomonas fluorescens Migula (strain X) had the highest antibacterial activity. When extracts of these organisms were applied to Nicotiana tabacum L. cultures, they reduced the growth of accidental contaminants. In the case of B. subtilis and P. fluorescens strains, equivalent extracts did not reduce fresh weight yields of uncontaminated N. tabacum cultures over four growth passages.

TL;DR: Electron microprobe analyses support the hypothesis that in developing root steles specific accumulation of lead occurs in the protophloem cells, and the observed distributions of lead are discussed in relation to phloem and root-tip structure and function.

TL;DR: Investigation of the influence of a wide range of concentrations of lead on the growth and development of Raphanus sativus found root extension offered the most sensitive reflection of lead toxicity over a range of lead concentrations, although effects were also seen on the development of root hairs and secondary roots.

TL;DR: Phytoremediation uses plants to remove pollutants from the environment and the recent discovery that certain chelating agents greatly facilitate metal uptake by soil-grown plants can make this technology a commercial reality in the near future.

TL;DR: The effects of excess heavy metals and aluminium on those functions which will alter plant water relations are considered, and the importance of distinguishing between low water availability in mine and serpentine soils and toxicity effects in plants which may impair the regulation of a plant's water household is placed.
Abstract: High metal availability, arising from mining and industrial activities, disposal of sewage sludge or soil acidification, is an increasing problem in agriculture and forestry. Metal toxicity causes multiple direct and indirect effects in plants which concern practically all physiological functions. In this review we consider the effects of excess heavy metals and aluminium on those functions which will alter plant water relations. After a brief comment on the metal effects in cell walls and plasmalemma, and their consequences for cell expansion growth, the influences of high metal availability on the factors which regulate water entry and water exit in plants are considered. Emphasis is placed on the importance of distinguishing between low water availability in mine and serpentine soils and toxicity effects in plants which may impair the regulation of a plant's water household. Examples on water relations of both plants grown on metalliferous soil and hydroponics are discussed. The effects of met...

TL;DR: In this article, the effects of heavy metals on plant metabolism were investigated using the examples of cadmium and lead and the basic mechanisms providing for plant resistance to excess Cd and Pb are elucidated.
Abstract: Using the examples of cadmium and lead, the review considers the various toxic effects exerted by these heavy metals. Putative specific and nonspecific mechanisms of the toxic effects of the heavy metals and plant responses are discussed together with the issue of Cd and Pb accumulation in various plant organelles, cells, tissues, and organs. The basic mechanisms providing for plant resistance to excess Cd and Pb are elucidated. These data are used to schematically outline the changes in plant metabolism produced by these heavy metals.

TL;DR: In this paper, the authors investigated the growth performance of two populations of Silene dioica (Melandrium sylvestre), one from a copper mine and another from a non-mine soil.
Abstract: Nearly 60 years ago, Prat (1934) initiated the research of heavy metal resistance in plants when he was analysing the growth performance of two populations of Silene dioica (Melandrium sylvestre), one from a copper mine and one from a non-mine soil. He was able to demonstrate a heritable copper resistance in the mine population, relative to the non-mine population, which he explained as a result of evolution by natural selection. Nearly 20 years later Bradshaw (1952) and Baumeister (1954) started further research on ecological and physiological differentiation between plants from metal-enriched and noncontaminated habitats. The species chosen for study were predominantly Agrostis capillaris in the Bradshaw group (Jowett 1959; Gregory 1965; McNeilly 1965; Antonovics 1966) and Silene vulgaris in the Baumeister group (Broker 1962; Ernst 1964; Gries 1965; Riither 1966). In the late 1950s Duvigneaud (1958), while studying the vegetation on metalliferous soils in Central Africa, added to the above approaches a phytogeographic one and introduced the study of speciation processes in metallophytes. In the 1950s, the study of evolutionary and physiological aspects of metal resistance was hampered by the absence of convenient techniques for measuring metal concentrations in small plant samples. The techniques available for metal analysis were either timeconsuming, such as phase separation (Ernst 1964), or costly and only applicable for laboratory-raised plant material, i.e. radiolabelling (Turner & Gregory 1967; Peterson 1969). Only after applying atomic absorption spectrophotometry on wet-ashed plant material (Reilly 1967) did time and cost-effective metal analyses become possible.
