Selenium in plants by Elizabeth A.H. Pilon-Smits,Lenny H.E. Winkel,Zhi-Qing Lin Pdf

This book covers many facets of plant selenium (Se) accumulation: molecular genetics, biochemistry, physiology, and ecological and evolutionary aspects. Broader impacts and applications of plant Se accumulation also receive attention. Plant Se accumulation is very relevant for environmental and human health. Selenium is both essential at low levels and toxic at high levels, and both Se deficiency and toxicity are problems worldwide. Selenium can positively affect crop productivity and nutritional value. Plants may also be used to clean up excess environmental Se. Selenium in plants has profound ecological impact, and likely contributes to Se movement in ecosystems and global Se cycling.

Selenium Supplementation in Horticultural Crops by Alžbeta Hegedűsová,Ondrej Hegedűs,Silvia Jakabová,Alena Andrejiová,Miroslav Šlosár,Ivana Mezeyová,Marcel Golian Pdf

Selenium plays a significant role in preventing certain types of cancer and cardiovascular diseases. The level of Selenium in the human body depends on its concentration in food. In turn, the content in vegetable crops is a function of the soil-plant system. There are many countries in the world with low Selenium content in the soil. The average daily human intake is thus limited through food chain. Analysis of Selenium status suggests that fortification of the soil substrate with Sodium Selenate, and foliar application to agricultural crops are both effective means of Selenium enrichment. Our intention for this publication is to present the possibilities of augmenting Selenium content by biofortification of soils and plants through differentiated nutrition. In the first part of the monograph, the results of Selenium supplementation in model vegetation experiments are presented. The next part of the monograph presents the results of foliar supplementation of Selenium in field conditions. This book is an outstanding reference source for plant breeders and researchers engaged in biofortification of horticulture crops. It is also beneficial to agricultural companies and other stakeholders.

Selenium Contamination in Water by Pooja Devi,Pardeep Singh,Arindam Malakar,Daniel Snow Pdf

The contamination of environment and water resources by Selenium (Se) and its oxyanions from various sources are emerging contaminants of significant health and environmental concern. The primary sources include agricultural drainage water, mine drainage, residues from fossil fuels, thermoelectric power plants, oil refineries, and metal ores. Various methods and technologies have been developed which focus on the treatment of selenium-containing waters and wastewater. High concentrations of selenium in water cause various adverse impact to human health, such as carcinogenic, genotoxic, and cytotoxic effects. But in the lower concentrations, it is a useful constituent of the biological system. The range between toxicity and deficiency of selenium is minimal (40 to 400 μg per day), due to its dual nature. Selenium Contamination in Water contains the latest status and information on selenium’s origin, its chemistry and its toxicity to humans. The book represents a comprehensive and advanced reference book for students, researchers, practitioners, and policymakers in working in the field of metalloids, in particular selenium. A special emphasis is given on its geological distribution, monitoring techniques, and remedial technologies. As such, the authors critically analyze the various techniques used for the monitoring and removal of selenium from water. Featuring chapters arranged according to the major themes of the latest research, with specific case-studies from industrial experiences of selenium detection and removal, Selenium Contamination in Water will be particularly valued by researchers, practitioners, and policymakers in working in the field of metalloids including selenium.

Selenium and Nano-Selenium in Environmental Stress Management and Crop Quality Improvement by Mohammad Anwar Hossain,Golam Jalal Ahammed,Zsuzsanna Kolbert,Hassan El-Ramady,Tofazzal Islam,Michela Schiavon Pdf

Crop plants growing under field conditions are constantly exposed to various abiotic and biotic stress factors leading to decreased yield and quality of produce. In order to achieve sustainable development in agriculture and to increase agricultural production for feeding an increasing global population, it is necessary to use ecologically compatible and environmentally friendly strategies to decrease the adverse effects of stresses on the plant. Selenium is one of the critical elements from the biological contexts because it is essential for human health; however, it becomes toxic at high concentrations. It has been widely reported that selenium can promote plant growth and alleviate various stresses as well as increase the quantity and quality of the yield of many plant species. Nonetheless, at high concentrations, selenium causes phytotoxicity. In the last decade, nanotechnology has emerged as a prominent tool for enhancing agricultural productivity. The production and applications of nanoparticles (NPs) have greatly increased in many industries, such as energy production, healthcare, agriculture, and environmental protection. The application of NPs has attracted interest for their potential to alleviate abiotic and biotic stresses in a more rapid, cost-effective, and more sustainable way than conventional treatment technologies. Recently, research related to selenium-NPs-mediated abiotic stresses and nutritional improvements in plants has received considerable interest by the scientific community. While significant progress was made in selenium biochemistry in relation to stress tolerance, an in-depth understanding of the molecular mechanisms associated with the selenium- and nano-selenium-mediated stress tolerance and bio-fortification in plants is still lacking. Gaining a better knowledge of the regulatory and molecular mechanisms that control selenium uptake, assimilation, and tolerance in plants is therefore vital and necessary to develop modern crop varieties that are more resilient to environmental stress. This book provides a comprehensive overview of the latest understanding of the physiological, biochemical, and molecular basis of selenium- and nano-selenium-mediated environmental stress tolerance and crop quality improvements in plants. It helps researchers to develop strategies to enhance crop productivity under stressful conditions and to better utilize natural resources to ensure future food security and to reduce environmental contamination. Finally, this book is a valuable resource for promoting future research into plant stress tolerance, and a reference book for researchers working on developing plants tolerant to abiotic and biotic stressors as well as bio-fortification and phytoremediation.
