We are expected to face the challenges of land use by 2050 because population will reach 9 billion while agricultural productivity losses are expected due to overuse of lands. How can we feed the next generations in a manner that respects our finite natural resources? Managing our resources in a sustainable way have only begun for selected crops. Much remains to be done to increase food yield. Cropping practices capable of sustainable production need to be elaborated, especially in fragile ecosystems. Typical applications will include the improvement and use of genetic resources; crop management and diversification; diffusion of improved varieties; development of cropping systems; sustainable cropping systems for areas prone to environmental degradation; use of agro-ecological data for crop production forecasting; and networks for regional coordination, and data exchange. The impetus behind this book is to bring attention to a cropping system that bears direct relevance to sustainable agriculture and food security. "Underutilized" crops are found in numerous agricultural ecosystems and often survive mainly in marginal areas. It is timely to review their status because, in recent decades, scientific and economic interests have emerged which focus on lesser-known cultivated species. Underutilized crops have a great potential to alleviate hunger directly, through increasing food production in challenging environments where major crops are severely limited. "Global Perspectives on Underutilized Crops" is therefore topical and highlights the unmet agricultural challenges that we face today. This book is an important resource for students and researchers of crop science and agricultural policy makers. © Springer International Publishing AG, part of Springer Nature 2018.

Application of farmyard manure (FYM) to such soils may increase or decrease their availability and retention time. Calcareous soils contaminated with 100, 200, and 400mg kg–1 Ni, Zn, and Pb as chloride salts were used, and farmyard manure added (40g kg–1 for 90 days) with moisture contents at field capacity. Soil samples were drawn at 30 day intervals, and metals extracted with (AB-DTPA) C14H23NO3O10. With FYM application of 400 mg kg–1, Ni availability increased from 179 (day 30) to 240 mg kg–1 (day 90); Zn from 163 (day 30) to 230 mg kg–1 (day 90), but, Pb decreased from 214 to 161 mg kg–1. FYM forms multi-dentate complex which greatly enhances the Ni and Zn solubility, and organic matter immobilizes Pb in the soil. © 2017 Vilnius Gediminas Technical University (VGTU) Press.Öğe Mangrove ecosystems of Asia: Status, challenges and management strategies(Springer New York, 2014) Faridah-Hanum I.; Latiff A.; Hakeem K.R.; Ozturk M.The book provides an up-to-date account of mangrove forests from Asia, together with restoration techniques, and the management requirements of these ecosystems to ensure their sustainability and conservation.

Mechanisms and Adaptations.(Elsevier Inc., 2015) Sabir M.; Waraich E.A.; Hakeem K.R.; Öztürk M.; Ahmad H.R.; Shahid M.Metal contamination of soils is ubiquitous around the globe. Metals accumulate in the soils to toxic levels that may lead to accumulation of metals in plants to unacceptable levels. Metal accumulation is a subject of serious concern due to the threat to plant growth, soil quality, animal and human health. Cleaning up of the soils to remove metals is a current necessity, but it is a challenging task. Different technologies being used nowadays are ex situ which ensues in destruction of soil structure thus leaving it non-useable with poor vegetative cover. Growing plants to clean up the soils is a cost-effective and environmentally friendly alternative. Phytoremediation seems attractive due to non-invasive and non-destructive technology which leaves the soil intact and biologically productive. Plants use different adaptive mechanisms to accumulate or exclude metals, thus maintaining their growth. Accumulation and tolerance of metals by the plants is a complex phenomenon. Movement of metals across the root membrane, loading and translocation of metals through the xylem and sequestration and detoxification of metals at cellular and whole plant levels are important mechanisms adopted by accumulator plants. Understanding the mechanism involved in phytoremediation is necessary to effectively use this technique for metal-contaminated soils. This chapter discusses different mechanisms adopted by plants for remediation of metal-contaminated soils. © 2015 Elsevier Inc.

Therefore, in addition to being a reference for the professional researchers, it is also of great interest to students and their professors. Considering immense significance of plants for all lives on Earth, the major focus of research in plant biology has been to: (a) select plants that best fit the purposes of human, (b) develop crop plants superior in quality, quantity and farming practices when compared to natural (wild) plants, and (c) explore strategies to help plants to adapt biotic and abiotic/environmental stress factors. Accordingly the development of novel techniques and their applications have increased significantly in recent years. In particular, large amount of biological data have emerged from multi-omics approaches aimed at addressing numerous aspects of the plant systems under biotic or abiotic stresses. However, even though the field is evolving at a rapid pace, information on the cross-talks and/or critical digestion of research outcomes in the context of plant bioinformatics is scarce. "Plant Bioinformatics: Decoding the Phyta" is aimed to bridge this gap. © Springer International Publishing AG 2017. All Rights Reserved.Öğe Plant responses and tolerance to high temperature stress: Role of exogenous phytoprotectants(Springer International Publishing, 2015) Nahar K.; Hasanuzzaman M.; Ahamed K.U.; Hakeem K.R.; Ozturk M.; Fujita M.Among the abiotic stresses high temperature stress is one of the most detrimental stresses threatening higher plant productivity and survival throughout the world. Each degree Celsius increase of average growing season temperature may decrease crop yield and affect plant distribution. On the other hand, global average temperatures are supposed to increase from 1.8 to 4.0 °C or higher by 2100 as compared to the 1980-2000 average. Plants are intimidated by adverse effects of high temperature stresses. Protein denaturation, inactivation of enzymes, production of reactive oxygen species, and disruption of membrane structure are some of the primary damage effects of high temperature that are also responsible for damage of ultrastructural cellular components. These anomalies hamper plant growth and development. Although higher plants develop their own defense strategies to overcome the high temperature stress effects, these often are not enough, therefore substantial damage is observed. The metabolism in plants is altered in response to high temperature stress. The antioxidants, secondary metabolites, hormones, osmoprotectants, and many other essential biomolecules are modulated, which help to defend against high temperature impacts. Moreover, numerous studies have proved that as protectants the exogenously applied hormones, osmoregulators, antioxidants, signaling molecules, polyamines, and trace elements confer high temperature stress tolerance in the organisms. This chapter presents the responses of plants to high temperature stress and evaluates the role of exogenous protectants under high temperature stress. © Springer International Publishing Switzerland 2015.Öğe Plants, pollutants and remediation(Springer Netherlands, 2016) Öztürk M.; Ashraf M.; Aksoy A.; Ahmad M.S.A.; Hakeem K.R.In the era of current industrial and civil development, everyone is expressing a deep concern about the problem of environmental pollution. The majority of the global community has a vested interest in supporting and sustaining any move for the protection of environment. In the greater part of the last century it was the fast pace of industrialization, galloping demand for energy and reckless exploitation of natural resources that were mainly responsible for creating the problem of environmental pollution. In the current scenario, high illiteracy rates of the developing nations leads to increasing environmental pollution. When it comes to the hazards of environmental pollution, there is only a very thin dividing line between different countries. One pollutes and the other suffers-there are no eventual winners without significant changes globally. Pollution is posing serious threats to all kinds of diversities on earth in particular plants. The plant world is of vital importance for our planet. It is a worldwide priority aimed at better meeting the needs for food, livelihoods and nature. To meet the food demand of fast-growing population, global food production will have to be doubled. The sustainability of food production depends on the sustainability of plant resources and using tolerant varieties to augment food production. This volume therefore covers discussions on the recent developments in this connection and the emerging role of plants as indicators, remediation, and such related issues as biodiversity conservation and the effects of on edible plants. It reviews issues concerning the future of plant life. Taking cognizance of this, several experts from different parts of the globe have contributed from their experience and knowledge to the critical issues of "Environmental Pollution," and the "Role of Plants in this connection". © Springer Science+Business Media Dordrecht 2015.Öğe Relevance of proteomic investigations in plant abiotic stress physiology(2012) Hakeem K.R.; Chandna R.; Ahmad P.; Iqbal M.; Ozturk M.Plant growth and productivity are influenced by various abiotic stresses. Stressful conditions may lead to delays in seed germination, reduced seedling growth, and decreased crop yields. Plants respond to environmental stresses via differential expression of a subset of genes, which results in changes in omic compositions, such as transcriptome, proteome, and metabolome. Since the development of modern biotechnology, various research projects have been carried out to understand the approaches that plants have adopted to overcome environmental stresses. Advancements in omics have made functional genomics easy to understand. Since the fundamentals of classical genomics were unable to clear up confusion related to the functional aspects of the metabolic processes taking place during stress conditions, new fields have been designed and are known as omics. Proteomics, the analysis of genomic complements of proteins, has caused a flurry of activity in the past few years. It defines protein functions in cells and explains how those protein functions respond to changing environmental conditions. The ability of crop plants to cope up with the variety of environmental stresses depends on a number of changes in their proteins, which may be up-and downregulated as a result of altered gene expression. Most of these molecules display an essential function, either in the regulation of the response (e.g., components of the signal transduction pathway), or in the adaptation process (e.g., enzymes involved in stress repair and degradation of damaged cellular contents), allowing plants to recover and survive the stress. Many of these proteins are constitutively expressed under normal conditions, but when under stress, they undergo a modification of their expression levels. This review will explain how proteomics can help in elucidating important plant processes in response to various abiotic stresses. © 2012 Mary Ann Liebert, Inc.Öğe Soil Remediation and Plants: Prospects and Challenges(Elsevier Inc., 2014) Hakeem K.R.; Sabir M.; öztürk M.; Mermut A.R.The soil is being contaminated continuously by a large number of pollutants. Among them, heavy metals are an exclusive group of toxicants because they are stable and difficult to disseminate into non-toxic forms. The ever-increasing concentrations of such pollutants in the soil are considered serious threats toward everyone's health and the environment. Many techniques are used to clean, eliminate, obliterate or sequester these hazardous pollutants from the soil. However, these techniques can be costly, labor intensive, and often disquieting. Phytoremediation is a simple, cost effective, environmental friendly and fast-emerging new technology for eliminating toxic heavy metals and other related soil pollutants. Soil Remediation and Plants provides a common platform for biologists, agricultural engineers, environmental scientists, and chemists, working with a common aim of finding sustainable solutions to various environmental issues. The book provides an overview of ecosystem approaches and phytotechnologies and their cumulative significance in relation to solving various environmental problems. Identifies the molecular mechanisms through which plants are able to remediate pollutants from the soil. Examines the challenges and possibilities towards the various phytoremediation candidates. Includes the latest research and ongoing progress in phytoremediation. © 2015 Elsevier Inc. All rights reserved.
