Natural diversity has been extensively used to understand plant biology and improve crops. However, studies were commonly based on visual phenotypes or on a few measurable parameters. Nowadays, a large number of parameters can be measured thanks to next generation sequencing, metabolomics, proteomics, and transcriptomics thus providing an unprecedented resolution in the detection of natural diversity. This enhanced resolution offers new possibilities in terms of understanding plant biology. Technology advances also contribute to a better assessment of the biodiversity loss currently taking place. Hence, the topic presents an overview on efforts for maintaining biological diversity in crops, on possibilities offered by recent technologies in the assessment of natural variation, and ends with examples of the diversity found even at the cellular level.
Being a consumer is now integral to the human experience, something none of us can avoid. At the same time, many of the products that we buy come to us with histories steeped in highly unethical practices, such as worker exploitation, animal suffering, and environmental damage. Consuming Choices considers the ethical dimensions of consumer life by exploring several basic questions: Exactly what sorts of unethical practices are implicated in today's consumer products? Does moral culpability for these practices fall solely on the companies that perform them, or does it also fall upon consumers who purchase the products made with such practices? And most importantly, do consumers ever have moral obligations to avoid particular products? To answer, David T. Schwartz provides the most detailed philosophical exploration to date on consumer ethics. He utilizes historical and fictional examples to illustrate the types of wrongdoing currently implicated by consumer products in this age of globalization, offers a clear description of the relevant moral theories and important ethical concepts, and provides concrete suggestions on how to be a more ethical consumer.
The global community is far from achieving its objective of ending plastic pollution, unless more stringent and co-ordinated policies are implemented. A key question is: What are the plausible scenarios for the evolution of plastics in the absence of additional measures and, as well, with scaled-up policy action?
The onset of flowering is an important step during the lifetime of a flowering plant. During the past two decades, there has been enormous progress in our understanding of how internal and external (environmental) cues control the transition to reproductive growth in plants. Many flowering time regulators have been identified from the model plant Arabidopsis thaliana. Most of them are assembled in regulatory pathways, which converge to central integrators which trigger the transition of the vegetative into an inflorescence meristem. For crop cultivation, the time of flowering is of upmost importance, because it determines yield. Phenotypic variation for this trait is largely controlled by genes, which were often modified during domestication or crop improvement. Understanding the genetic basis of flowering time regulation offers new opportunities for selection in plant breeding and for genome editing and genetic modification of crop species.
Reversible ubiquitylation plays an important regulatory role in almost all aspects of cellular and organismal processes in plants. Its pervasive regulatory role in plant biology is primarily due to the involvement of a large set of ubiquitin system constituents (encoded by approximately 6% Arabidopsis genome), the huge number of important cellular proteins targeted as substrates, and various drastic effects on the modified proteins. The major components of the ubiquitin system include a large set of enzymes and proteins involved in ubiquitin conjugation (E1s, E2s, and E3s) and deconjugation (deubiquitinases of different classes) and post ubiquitin conjugation components such as ubiquitin rec...
With more than half the world’s population now living in urban areas, ‘fairness’ and ‘justice’ within the city are key concepts in contemporary political debate. This book examines the theory and practice of justice in and of the city through a multi-disciplinary collaboration, which draws on a wide range of expertise. By bringing diverse disciplinary and theoretical perspectives into conversation with each other to explore the (in) justices in urban environment, education, mobility and participation the book makes a significant contribution to our understanding of justice and fairness in and of the city. It will be a valuable resource for academic researchers and students across a range of disciplines including urban and environmental studies, geography, planning, education, ethics and politics.
Abiotic stresses are the major cause that limits productivity of crop plants worldwide. Plants have developed intricate machinery to respond and adapt over these adverse environmental conditions both at physiological and molecular levels. Due to increasing problems of abiotic stresses, plant biotechnologists and breeders need to employ new approaches to improve abiotic stress tolerance in crop plants. Although current research has divulged several key genes, gene regulatory networks and quantitative trait loci that mediate plant responses to various abiotic stresses, the comprehensive understanding of this complex trait is still not available. This e-book is focused on molecular genetics and genomics approaches to understand the plant response/adaptation to various abiotic stresses. It includes different types of articles (original research, method, opinion and review) that provide current insights into different aspects of plant responses and adaptation to abiotic stresses.
Over the past four decades, there has been immense progress in every area of lignin science, ranging from the enzymology of lignin biodegradation, to the delignification of wood fiber during pulping and bleaching, to advances in spectroscopy. Lignin and Lignans: Advances in Chemistry captures the developments that have been achieved by world-class
“To me, an object that was once the height of elegance but is now a bit battered has far more allure than something brand new.” Pearl Lowe in The Daily Telegraph Pearl Lowe has a passion for vintage finds with character—jewel-toned velvet sofas, hand-dyed lace curtains, gleaming lacquer cabinets—and these are the essential ingredients of Faded Glamour, a gloriously decadent and perfectly lived-in decorating style. With evocative photography, Pearl’s beautiful Georgian home is revealed, showcasing her trademark blend of grandly romantic and cool rock ’n’ roll interiors. Take a tour through the colorful living rooms, intimate bedrooms, and plush bathrooms of her creative friends’ unique homes. There are hand-painted peacocks and an emerald silk bedspread in the charming house of a renowned British fashion designer; bright contemporary paintings on the perfectly rustic plaster walls of Hauser and Wirth in Somerset; a rainbow staircase and vivid embroidered wall hangings in the home of an eclectic jewelry designer, and so much more.
