Download or read book Global Change, Clonal Growth, and Biological Invasions by Plants written by Fei-Hai Yu and published by Frontiers Media SA. This book was released on 2016-11-29 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are few more active frontiers in plant science than helping understand and predict the ecological consequences of on-going, global changes in climate, land use and cover, nutrient cycling, and acidity. This collection of research papers and reviews focuses on how these changes are likely to interact with two important factors, clonal growth in plants and the introduction of species into new regions by humans, to reshape the ecology of our world. Clonal growth is vegetative reproduction in which offspring remain attached to the parent at least until establishment. Clonal growth is associated with the invasiveness of introduced species, their tendency to spread after introduction and negatively affect other species. Will changes in climate, land cover, or nutrients further increase biological invasions by introduced, clonal plants? The articles in this book seek to address this question with new research and theory on clonal growth and its interactions with invasiveness and other components of global change.

Download or read book New Perspectives on the Biology of Nectaries and Nectars written by Clay Carter and published by Frontiers Media SA. This book was released on 2019-08-27 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The number of currently known, described and accepted plant species is ca 374,000, of which approximately 295,00 (79%) are angiosperms. Almost 90% of this huge number of flowering plants is pollinated by animals (mostly insects) via nectar-mediated interactions. Notably, three-fourths of the leading global crop plants produce nectar and are animal pollinated, which is estimated to account for one-third of human food resources. Nectar can also be produced on tissues outside of flowers, by so-called extrafloral nectaries, and commonly mediate interactions with ‘body-guard’ ants and other pugnacious insects that defend the plant from herbivores. Extrafloral nectar is present in almost 4,000 plant species, a majority of them in the angiosperms. This brief summary on the occurrence of nectar in the plant kingdom is just to highlight that nectar has a fundamental role in two basal functions that allow the maintenance of our ecosystems: sexual plant reproduction and protection of plants from herbivory. Despite playing essential ecological and evolutionary functions, our current knowledge about nectar is largely incomplete; however, new research directions and perspectives on nectaries and nectars have arisen in recent years. In the last two decades, there were only a few ‘moments’ in which nectar was the main character in international meetings or in published books. In 2002, the first (and only) international meeting “Nectar and nectary: from biology to biotechnology” dedicated exclusively to nectar and nectaries was held in Italy (Montalcino, Siena) and in 2003 the proceedings were published in a special volume of Plant Systematics and Evolution (238, issue 1-4). In 2007, the book Nectar and Nectaries was published (Springer) with most of the contributions provided by authors that attended the meeting in Italy. Another book dedicated to nectar was published in 2015 (Nectar: Production, Chemical Composition and Benefits to Animals and Plants, Nova Science Publishers) covering aspects mainly related to nectar chemical composition and plant-pollinator interactions. Similarly, symposia focused on nectar have been organized within the International Botanical Congress in 2011 and 2017. Considering that the last few years has yielded essential developments in the understanding of nectar biology, we thought now is the moment to further stimulate research on this important topic. This aim has been met through 18 papers published in our Research Topic New Perspectives on the Biology of Nectaries and Nectars, with subjects spanning evolution and ecology to nectar chemistry and nectary structure.

Available in PDF, EPUB and Kindle. Book excerpt: Photobiology is an important area of biological research since a very large number of living processes are either dependent on or governed by light that we receive from the Sun. Among various subjects, photosynthesis is one of the most important, and thus a popular topic in both molecular and organismic biology, and one which has made a considerable impact throughout the world since almost all life on Earth depends upon it as a source of food, fuel and oxygen. However, for growth of plants, light is equally essential, and research on photomorphogenesis has revealed exciting new developments with the application of newer molecular biological approaches. The present book brings together and integrates various aspects of photosynthesis, biology of pigments, light regulation of chloroplast development, nuclear and chloroplast gene expression, light signal transduction, other photomorphogenetic processes and some photoecological aspects under one cover. The chapters cover biochemical and molecular discussions of most of the above topics in a comprehensive manner and include a wide range of `hot topics' that are currently under investigation in the field of photobiology of cyanobacteria, algae and plants. The authors of this book are selected international authorities in their fields from USA, Europe, Australia and Asia. The book is designed primarily to be used as a text book by graduates and post-graduates. It is, however, also intended to be a resource book for new researchers in plant photobiology. Several introductory chapters are designed as suitable reading for undergraduate courses in integrative and molecular biology, biochemistry and biophysics.

Download or read book Advances in Plastid Biology and Its Applications written by Niaz Ahmad and published by Frontiers Media SA. This book was released on 2016-12-12 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the distinguishing features of plants is the presence of membrane-bound organelles called plastids. Starting from proplastids (undifferentiated plastids) they readily develop into specialised types, which are involved in a range of cellular functions such as photosynthesis, nitrogen assimilation, biosynthesis of sucrose, starch, chlorophyll, carotenoids, fatty acids, amino acids, and secondary metabolites as well as a number of metabolic reactions like sulphur metabolism, The central role of plastids in many aspects of plant cell biology means an in-depth understanding is key for a holistic view of plant physiology. Despite the vast amount of research, the molecular details of many aspects of plastid biology remains limited. Plastids possess their own high-copy number genome known as the plastome. Manipulation of the plastid genome has been developed as an alternative way to developing transgenic plants for various biotechnological applications. High-copy number of the plastome, site-specific integration of transgenes through homologous recombination, and potential to express proteins at high levels (>70% of total soluble proteins has been reported in some cases) are some of the technologies being developed. Additionally, plastids are inherited maternally, providing a natural gene containment system, and do not follow Mendelian laws of inheritance, allowing each individual member of the progeny of a transplastomic line to uniformly express transgene(s). Both algal and higher plant chloroplast transformation has been demonstrated, and with the ability to be propagated either in bioreactors or in the field, both systems are well suited for scale up of production. The manipulation of chloroplast genes is also essential for many approaches that attempt to increase biomass accumulation or re-routing metabolic pathways for biofortification, food and fuel production. This includes metabolic engineering for lipid production, adapting the light harvesting apparatus to improve solar conversion efficiencies and engineering means of suppressing photorespiration in crop species, which range from the introduction of artificial carbon concentrating mechanisms, or those pre-existing elsewhere in nature, to bypassing ribulose bisphosphate carboxylase/oxygenase entirely. The purpose of this eBook is to provide a compilation of the latest research on various aspects of plastid biology including basic biology, biopharming, metabolic engineering, bio-fortification, stress physiology, and biofuel production.

Book excerpt: Harmonious, integrated functioning of the whole plant system requires that its various cells, tissues and organs should be able to communicate with each other, transferring a range of information on environmental conditions, physiological and microbial stresses etc. In this volume of Advances in Botanical Research incorporating Advances in Plant Pathology three articles are concerned with different aspects of plant signalling. McDonald and Davis consider how shoot systems respond to drying and N-deficient soil, in terms of their stomatal behaviour and growth, via the transmission of root-derived chemical signals. Malone considers the major hypotheses that have been proposed with particular attention being given to hydraulic pressure signals and the hydraulic dispersal of chemical signals. At a different, intracellular level of communication, a wide variety of second messengers couple extracellular stimuli to a characteristic physiological response. Webb et al. Consider progress made in establishing similar roles for calcium in plant signalling in the context of the mammalian paradigms. The effects of UV-B radiation on plants have been extensively investigated in recent years. Jordan considers progress in understanding the chain of events from perception of UV-B to signal transduction and consequent changes in gene expression and regulation. Smith and Smith assess the various hypotheses erected over the years to explain structure and function of the host-parasite interface formed by vesticular-arbuscular (VA) mycorrhizas, an important and widespread mutualistic symbioses of a wide range of higher and some lower plants.

Book excerpt: "Sun Protection in Man" looks at the beneficial and harmful effects of solar radiation. The physiological consequences of sun exposure have been systematically studied starting at the end of the nineteenth century and we now have accumulated knowledge about how Caucasian and Asian skins reacts to solar radiation. The chemical effects of solar ultraviolet radiation have been analyzed with particular emphasis during the second half of the twentieth century. Research on micro-organisms has allowed us to understand the mechanisms of UV-induced mutagenesis and photosensitization. Studies with laboratory rodents have opened the path to the understanding of UV-induced immune-depression, carcinogenesis, photo-damage and photo-aging. The results of these studies have enabled other scientists to investigate the same phenomena in human organs such as the skin and the eye. UV radiation damages hair, as well. The present knowledge in these fields is summarized in some of the chapters of this monograph. Mass phenomenon in Europe with the generalization of summer vacations which were a consequence of social reforms introducing the concept of "paid vacations". This created a need for protection and opened a market for sunscreens. This monograph is concerned with sun protection as a whole and is not just "another book on sunscreens". Nonetheless, in these days of general concern, it is important to learn about the efficiency of sunscreens. Several authors discuss how to reduce the number of impinging photons and explain why sunscreens seem to offer less protection than expected. Guidelines are given on how to use sunscreens in everyday life, which are expressed rigorously though clearly, for access to the common reader. Our knowledge on the relationship between sun and humans is at the early stages of development. Industrial and commercial activities are concerned by the development of this knowledge, and rules have been and will be promulgated to guarantee efficacy and safety of sun-products. It is hoped that this monograph will be of interest to the scholar, the layman and the legislator.
