A transgenic organism is a plant, animal, bacterium, or other living organism that has had a foreign gene added to it by means of genetic engineering. Transgenic plants can arise by natural movement of genes between species, by cross-pollination based hybridization between different plant species (which is a common event in flowering plant evolution), or by laboratory manipulations by artificial insertion of genes from another species. Methods used in traditional breeding that generate transgenic plants by non-recombinant methods are widely familiar to professional plant scientists, and serve important roles in securing a sustainable future for agriculture by protecting crops from pest and helping land and water to be used more efficiently.
There is worldwide interest in the biosafety issues related to transgenic crops because of issues such as increased pesticide use, increased crop and weed resistance to pesticides, gene flow to related plant species, negative effects on nontarget organisms, and reduced crop and ecosystem diversity. This book is intended to provide the basic information for a wide range of people involved in the release of transgenic crops. These will include scientists and researchers in the initial stage of developing transgenic products, industrialists, and decision makers. It will be of particular interest to plant scientists taking up biotechnological approaches to agricultural improvement for developing nations.

This specially formulated collection features 3 reviews of current topics and key research in sweetpotato. The first chapter examines the origin and dispersal of sweetpotato, considers in vitro germplasm storage in sweetpotato genebanks, and looks at the importance of managing sweetpotato crop wild relatives (CWR). The chapter also considers the specific issues associated with sweetpotato germplasm, as well as the application of next-generation sequencing to sweetpotato and its CWR. The second chapter reviews the development and application of genetic transformation and trait improvement to sweetpotato, including the development of sweetpotato plants which are resistant to disease and abiotic stress, and sweetpotatoes with improved starch quality and higher anthocyanin content. The final chapter examines the nutritional contribution made by OFSP (orange-fleshed sweetpotato) in poor rural communities in Malawi, Ghana, Nigeria and Burkina Faso; sustainable breeding and seed systems; and effective commercialisation and marketing to benefit the communities concerned. This chapter includes detailed case studies from Ghana and Malawi.

Transcription Factors for Abiotic Stress Tolerance in Plants highlights advances in the understanding of the regulatory network that impacts plant health and production, providing important insights for improving plant resistance. Plant production worldwide is suffering serious losses due to widespread abiotic stresses increasing as a result of global climate change. Frequently more than one abiotic stress can occur at once, for example extreme temperature and osmotic stress, which increases the complexity of these environmental stresses. Modern genetic engineering technologies are one of the promising tools for development of plants with efficient yields and resilience to abiotic stresses. Hence deciphering the molecular mechanisms and identifying the abiotic stress associated genes that control plant response to abiotic stresses is a vital requirement in developing plants with increased abiotic stress resilience. Addressing the various complexities of transcriptional regulation, this book includes chapters on cross talk and central regulation, regulatory networks, the role of DOF, WRKY and NAC transcription factors, zinc finger proteins, CRISPR/CAS9-based genome editing, C-Repeat (CRT) binding factors (CBFs)/Dehydration responsive element binding factors (DREBs) and factors impacting salt, cold and phosphorous stress levels, as well as transcriptional modulation of genes involved in nanomaterial-plant interactions. Transcription Factors for Abiotic Stress Tolerance in Plants provides a useful reference by unravelling the transcriptional regulatory networks in plants. Researchers and advanced students will find this book a valuable reference for understanding this vital area.

This volume continues the retrospective analyses of Volumes I and II, but goes beyond that in an attempt to understand how phenolic acids are partitioned in seedling-solution and seedling-microbe-soil-sand culture systems and how phenolic acid effects on seedlings may be related to the actual and/or conditional physicochemical properties (e.g., solubility, hydrophobicity, pKa, molecular structure and soil sorption/desorption) of simple phenolic acids. Specifically, it explores the quantitative partitioning (i.e., source-sink relationships) of benzoic and cinnamic acids in cucumber seedling-solution and cucumber seedling-microbe-soil-sand systems and how that partitioning may influence phenolic acid effects on cucumber seedlings. Regressions, correlations and conceptual and hypothetical models are used to achieve these objectives. Cucumber seedlings are used as a surrogate for phenolic acid sensitive herbaceous dicotyledonous weed seedlings. This volume was written specifically for researchers and their students interested in understanding how a range of simple phenolic acids and potentially other putative allelopathic compounds released from living plants and their litter and residues may modify soil chemistry, soil and rhizosphere microbial biology, seedling physiology and seedling growth. In addition, this volume describes the potential relationships, where they may exist, for direct transfer of organic compounds between plants, plant communication and plant-plant allelopathic interactions and addresses the following questions: Can physicochemical properties of phenolic acids be used as tools to help understand the complex behavior of phenolic acids and the ultimate effects of phenolic acids on sensitive seedlings? What insights do laboratory bioassays and the conceptual and hypothetical models of laboratory systems provide us concerning the potential behavior and effects of phenolic acids in field systems? What potential role may phenolic acids play in broadleaf-weed seedling emergence in wheat debris cover crop no-till systems?

"From the beginning of this book to the end, it has been Professor Hochmuth's intent to address and educate with a complete synopsis of what he calls '...the wealth of research addressing the challenges' in sustainable growth of vegetables... I believe he has succeeded." (Plant Science Bulletin - Botanical Society of America) Sustainability involves meeting current needs without compromising the ability to meet future requirements. Like other crops, vegetable cultivation faces a number of challenges in ensuring sustainable production. These challenges include the need to improve yields and quality to meet rising demand and higher consumer expectations, the need to reduce the ongoing threats from pathogens and pests. Focussing on temperate cultivation, Achieving sustainable cultivation of vegetables summarises the wealth of research addressing these challenges, from breeding improved varieties to better techniques for cultivation and crop protection. Part 1 reviews advances in physiology and breeding. Parts 2-3 summarise advances in cultivation and pest management. The final part includes case studies on the breeding and cultivation of key vegetables such as carrot, lettuce and cabbage. With its distinguished editor and range of expert authors, this will be a standard reference for horticultural scientists in universities, government and other research centres involved in supporting vegetable cultivation, as well as companies supporting the vegetable sector.
