The physiological and molecular mechanisms of tolerance to osmotic and ionic components of salinity stress are reviewed at the cellular, ... Salt Tolerance Mechanisms of Plants. Change style powered by CSL. Heavy metal tolerance to plants represents the ability of particular plants to thrive under conditions that are characterized by excess of metal ions, which have toxic effect for other plants (Macnair et al. Trace metal elements are essential for plant growth but become toxic at high concentrations, while some non-essential elements, such as Cd and As, show toxicity even in traces. This book covers the evolution of heavy metal tolerance in groups of plants, fungi, and protists. Copper tolerance in normal populations of different plant species. The efficiency of intracellular chelation of heavy metal ions with the participation of organic acids is considered due to the importance of this strategy in hyperaccumulators and non-hyperaccumulators to improve metal tolerance in plants. Eva van Zelm, Yanxia Zhang, Christa Testerink Vol. This review summarizes various tolerance strategies of plants under heavy metal toxicity covering the role of metabolites (metabolomics), trace elements (ionomics), transcription factors (transcriptomics), various stress-inducible proteins (proteomics) as well as the role of plant hormones. Papers on the ecology of metal contaminated habitats and macroevolutionary, physiological, molecular and microevolutionary aspects are included in this book. Heavy metal stress is a major growth- and yield-limiting factor for plants. as those metals having a density greater than five, include about thirty-eight elements. BjDHNs Confer Heavy-metal Tolerance in Plants BjDHNs Confer Heavy-metal Tolerance in Plants Xu, Jin; Zhang, Yu; Wei, Wei; Han, Lu; Guan, Zi; Wang, Zi; Chai, Tuan 2007-09-22 00:00:00 Mol Biotechnol (2008) 38:91���98 DOI 10.1007/s12033-007-9005-8 RESEARCH Jin Xu Æ Yu Xiu Zhang Æ Wei Wei Æ Lu Han Æ Zi Qiu Guan Æ Zi Wang Æ Tuan Yao Chai Published online: 22 September ��� Castor plant is widely studied due to its tolerance to the effects of heavy metal contaminated soils, owing to its large biomass content and high accumulating capacity. This volume provides a synthesis of recent work on evolutionary aspects of metal tolerance in plants. 2000) . While accumulated metal ions are detoxified by phytochelatins, which are synthesized from glutathione in plants during their exposure to heavy metals. Stirling. The book discusses the physiological, genetic and molecular aspects of metal tolerances. The discovery of phytochelatins, 款���glutarnyl peptides, containing only glutamic acid, cysteine and glycine, in plants is described and evidence for their role in heavy metal tolerance is assessed. Thus, metal homeostasis is tightly regulated in plants. INTRODUCTION A heavy metal is toxic when relatively it is dense metal or metalloid that is noted for its potential toxicity, especially in environmental contexts. S. K. Yadav, ���Heavy metals toxicity in plants: an overview on the role of glutathione and phytochelatins in heavy metal stress tolerance of plants,��� South African Journal of Botany, vol. Plants have a range of potential mechanisms at the cellular level that might be involved in the detoxification and thus tolerance to heavy metal stress. Boca Raton, FL: CRC Press. DNA synthesis, protein modi詮�cations, redox reactions in the chloroplast and the mitochondrion, sugar metabolism, and nitrogen 詮�xation. Heavy Metal Tolerance in Plants J .ANTONOVIOS Department of Biology. Author information: (1)Department of Biology, Graduate University of Chinese Academy of Sciences, Beijing, 100049, PR China. The tolerance of protoplasts prepared from plants grown without metal added was assayed after 24 h with increasing concentrations of Ni, Zn and Cd ().An absolute viability of 80% was routinely obtained in the control vessels after 24 h, and the viability of protoplasts in metal���containing vessels was normalized to the control mean for each experiment.
