Book Description
Molecular and ecophysiological responses of Populus euphratica (Oliv.) and Arabidopsis thaliana (L.) to salt stress
Author: Eric Aart Ottow
Publisher: Cuvillier Verlag
ISBN: 3736913796
Category : Science
Languages : de
Pages : 153
Book Description
Populus euphratica (Oliv.) is capable of growth in saline environments. However, little is known on the molecular and ecophysiological traits of its salt resistance. The aim of the present investigation was to gain new insights into the strategies of P. euphratica to cope with elevated NaCl concentrations. Laboratory experiments with young P. euphratica plants revealed that Na + was primarily accumulated in leaves and roots while the stems were less affected. Severe salt stress caused a complete die-back of the salt-sensitive poplar hybrid Populus x canescens but did not injure P. euphratica despite accumulation of nearly 4% Na + in its leaves. X-ray microanalyses showed that apoplastic rather than vacuolar salt accumulation was the primary strategy to protect the cytosol against Na + toxicity. The ability to cope with salinity was also associated with the maintenance of cytosolic K + concentrations. Salt exposure induced development of leaf succulence due to an increase in cell number and cell volume, thus contributing to Na + resistance by dilution the salt concentration.

Biology of Populus and Its Implications for Management and Conservation
Author: National Research Council Canada
Publisher: NRC Research Press
ISBN: 9780660165066
Category : Nature
Languages : en
Pages : 560
Book Description
"Poplar is increasingly recognized as an excellent model tree for the study of tree growth and its underlying physiology and genetics. By studying trees of the genus Populus (poplars, cottonwoods, aspens), which in their native ecosystems play a major role in the re-colonization of sites after disturbances, new insights have been gained into plantation culture and the development of improved cultivars. Of the 20 chapters in this publication, editored by an international group of researchers, one section deals with systematics, genetics, genetic manipulation and biotic interactions of Populus, while the other deals with stress response and the physiology of growth and productivity" --

Water and Solute Permeability of Plant Cuticles
Author: Lukas Schreiber
Publisher: Springer Science & Business Media
ISBN: 3540689451
Category : Science
Languages : en
Pages : 306
Book Description
Transport properties of plant cuticles are important for different ?elds of modern plant sciences. Ecologists and physiologists are interested in water losses to the environment via the cuticle. Penetration of plant protecting agents and nutrients into leaves and fruits is relevant for research in agriculture and plant protection. Ecotoxicologists need to know the amounts of environmental xenobiotics which accumulate in leaves and other primary plant organs from the environment. For all of these studies suitable methods should be used, and a sound theoretical basis helps to formulate testable hypotheses and to interpret experimental data. Unnecessary experiments and experiments which yield ambiguous results can be avoided. In this monograph, we have analysed on a molecular basis the movement of molecules across plant cuticles. Based on current knowledge of chemistry and str- ture of cuticles, we have characterised the aqueous and lipophilic pathways, the nature and mechanisms of mass transport and the factors controlling the rate of movement. We have focused on structure–property relationships for penetrant tra- port, which can explain why water and solute permeabilities of cuticles differ widely among plant species. Based on this knowledge, mechanisms of adaptation to en- ronmental factors can be better understood, and rates of cuticular penetration can be optimised by plant physiologists and pesticide chemists.

Salt Stress in Plants
Author: Parvaiz Ahmad
Publisher: Springer Science & Business Media
ISBN: 1461461081
Category : Science
Languages : en
Pages : 518
Book Description
Environmental conditions and changes, irrespective of source, cause a variety of stresses, one of the most prevalent of which is salt stress. Excess amount of salt in the soil adversely affects plant growth and development, and impairs production. Nearly 20% of the world’s cultivated area and nearly half of the world’s irrigated lands are affected by salinity. Processes such as seed germination, seedling growth and vigour, vegetative growth, flowering and fruit set are adversely affected by high salt concentration, ultimately causing diminished economic yield and also quality of produce. Most plants cannot tolerate salt-stress. High salt concentrations decrease the osmotic potential of soil solution, creating a water stress in plants and severe ion toxicity. The interactions of salts with mineral nutrition may result in nutrient imbalances and deficiencies. The consequence of all these can ultimately lead to plant death as a result of growth arrest and molecular damage. To achieve salt-tolerance, the foremost task is either to prevent or alleviate the damage, or to re-establish homeostatic conditions in the new stressful environment. Barring a few exceptions, the conventional breeding techniques have been unsuccessful in transferring the salt-tolerance trait to the target species. A host of genes encoding different structural and regulatory proteins have been used over the past 5–6 years for the development of a range of abiotic stress-tolerant plants. It has been shown that using regulatory genes is a more effective approach for developing stress-tolerant plants. Thus, understanding the molecular basis will be helpful in developing selection strategies for improving salinity tolerance. This book will shed light on the effect of salt stress on plants development, proteomics, genomics, genetic engineering, and plant adaptations, among other topics. The book will cover around 25 chapters with contributors from all over the world.
