This book was released on 2020-04-24 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the first postulation of auxin function by the Darwins, many other plant hormones have been identified and most of them have been found to be synthesized at different sites from their places of action. Hormone transport and thus the responsible hormone transporters are therefore essential for a precise regulation of plant hormone action, which has been repeatedly supported by severe developmental and physiological phenotypes reported for hormone transporter loss-of-function mutants. Plant transporters have been shown to be involved in short and long-distance transport of hormones. Short-distance transport between cells seems to be sufficient for a local hormone action in some tissues (such as seeds), which seem to require exporter and importer proteins in adjacent cells as shown for example for abscisic acid. During long distance transport with the transpiration stream or in the phloem, demonstrated for many (but not all) plant hormones (including auxins, abscisic acid, cytokinins, gibberelins, strigolactones, and salicylic acid), transporters are thought to function in loading and unloading processes. Similarly, in cases where long-distance transport is achieved by cell-to-cell transport (such as for auxins), the highly coordinated action of import and export transporters at the contact surfaces of neighboring cells is apparently needed, however, all these processes are far from being understood on the molecular level. Currently, it appears that many hormones are transported by members of distinct transporter classes, ranging from primary active pumps (that couple hormone translocation to direct ATP hydrolysis), antiporters and symporters (that use the proton motive force to create hormone concentration gradients), and to facilitators. Among those, the ATP-binding cassette (ABC) family and the Nitrate transport1/ Peptide transporter family (NPF) seem to be dominant but currently it is unclear how individual transporters cooperate to achieve a systemic level of transport. Furthermore, in most cases several pairs of importers and exporters are required but how these are correct allocated in order to guarantee the function of a complex hormonal network is unknown. While remarkable progress has been made on hormone transporter regulation on the transcription and post-transcriptional level for transporters involved in long-distance transport (such as auxin), regulation of transporter trafficking, stability and activity is less understood for other hormones.

Available in PDF, EPUB and Kindle. Book excerpt: Plant Hormones: Biosynthesis and Mechanisms of Action is based on research funded by the Chinese government's National Natural Science Foundation of China (NSFC). This book brings a fresh understanding of hormone biology, particularly molecular mechanisms driving plant hormone actions. With growing understanding of hormone biology comes new outlooks on how mankind values and utilizes the built-in potential of plants for improvement of crops in an environmentally friendly and sustainable manner. This book is a comprehensive description of all major plant hormones: how they are synthesized and catabolized; how they are perceived by plant cells; how they trigger signal transduction; how they regulate gene expression; how they regulate plant growth, development and defense responses; and how we measure plant hormones. This is an exciting time for researchers interested in plant hormones. Plants rely on a diverse set of small molecule hormones to regulate every aspect of their biological processes including development, growth, and adaptation. Since the discovery of the first plant hormone auxin, hormones have always been the frontiers of plant biology. Although the physiological functions of most plant hormones have been studied for decades, the last 15 to 20 years have seen a dramatic progress in our understanding of the molecular mechanisms of hormone actions. The publication of the whole genome sequences of the model systems of Arabidopsis and rice, together with the advent of multidisciplinary approaches has opened the door to successful experimentation on plant hormone actions. - Offers a comprehensive description of all major plant hormones including the recently discovered strigolactones and several peptide hormones - Contains a chapter describing how plant hormones regulate stem cells - Offers a fresh understanding of hormone biology, particularly molecular mechanisms driving plant hormone actions - Discusses the built-in potential of plants for improvement of crops in an environmentally friendly and sustainable manner

Download or read book Plant ABC Transporters written by Markus Geisler and published by Springer. This book was released on 2014-09-06 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the fascinating superfamily of plant ATP-binding cassette (ABC) transporters and their variety of transported substrates. It highlights their exciting biological functions, covering aspects ranging from cellular detoxification, through development, to symbiosis and defense. Moreover, it also includes a number of chapters that center on ABC transporters from non-Arabidopsis species. ABC proteins are ubiquitous, membrane-intrinsic transporters that catalyze the primary (ATP-dependent) movement of their substrates through biological membranes. Initially identified as an essential aspect of a vacuolar detoxification process, genetic work in the last decade has revealed an unexpectedly diverse variety of ABC transporter substrates, which include not only xenobiotic conjugates, but also heavy metals, lipids, terpenoids, lignols, alkaloids and organic acids. The discovery that members of the ABCB and ABCG family are involved in the movement of phytohormones has further sparked their exploration and provided a new understanding of the whole family. Accordingly, the trafficking, regulation and structure-function of ABCB-type auxin transporters are especially emphasized in this book.

Download or read book Genetically Engineered Crops written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-01-28 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.
