Book Description
Plants respond to various abiotic and biotic stress conditions through accumulation of phenolic compounds. The specificity of these phenolic compounds accumulation depends on the type of stress condition and the response of plant species. Light stress induces biosynthesis of phenolic acids and flavonoids in plants. Temperature stress initially induces biosynthesis of osmoprotective compounds and then later stimulates synthesis of antioxidant enzymes and antioxidant compounds such as flavonoids, tannins and phenolic acids in plant cells. Salinity causes oxidative stress in plants by inducing production of reactive oxygen species. To resist against oxidative stress plants produce polyphenols, flavonoids, anthocyanins, phenolic acids and phenolic terpenes. Plants biosynthesize phenols and flavonoids during heavy metal stress.to scavenge the harmful reactive oxygen species and to detoxify the hydrogen peroxide. Plants accumulate phenols at the infection sites to slow down the growth of microbial pathogens and restrict them at infected site. Plants also accumulates salicylic acid and H2O2 at the infection site to induce the systemic acquired resistance (SAR) against microbial pathogens. Plants accumulate phenolic compounds which act as inhibitor or toxicant to harmful nematodes, insects and herbivores. Hence, phenols regulate crucial physiological functions in plants to resist against different stress conditions.

Book Description
Phenolic compounds are considered secondary metabolites within the physiology of a plant. They have different functions, such as pollination systems, sun protection, protection against pathogens and diseases, etc.Research on these compounds has increased due to the number of molecules they can include and the different biological activities they demonstrate. It is important to know the methods of extracting molecules, the biosynthesis routes, and their relationship with activities that can benefit from their consumption. Therefore, the book includes chapters that provide information on extraction and optimization techniques, biosynthetic pathways, and the identification and characterization of miRNAs involved in the regulation of their biosynthesis.

Book Description
Polyphenols in Plants assists plant scientists and dietary supplement producers in assessing polyphenol content and factors affecting their composition. It also aids in selecting sources and regulating environmental conditions affecting yield for more consistent and function dietary supplements. Polyphenols play key roles in the growth, regulation and structure of plants and vary widely within different plants. Stress, growth conditions and plant species modify polyphenol structure and content. This book describes techniques to identify, isolate and characterize polyphenols, taking mammalian toxicology into account as well. - Defines conditions of growth affecting the polyphenol levels - Describes assay and instrumentation techniques critical to identifying and defining polyphenols, critical to researchers and business development - Documents how some polyphenols are dangerous to consume, important to dietary supplement industry, government regulators and lay public users

Book Description
These are just a few examples that illustrate the chemical diversity and use of phenolic compounds, the topic of ‘Phenolic Compound Biochemistry’. This book is written for researchers, instructors, advanced undergraduate students and beginning graduate students in the life sciences who wish to become more familiar with these and many other intriguing aspects of phenolic compounds. Topics covered include nomenclature, chemical properties, biosynthesis, including an up-to-date overview of the genetics controlling phenolic metabolism, isolation and characterization of phenolic compounds, phenolics used in plant defense, and the impact of phenolics on human health. The book is written in an accessible style, and assumes only basic knowledge of organic chemistry, biochemistry and cell physiology. More than 300 chemical structures and reaction schemes illustrate the text. Wilfred Vermerris is Associate Professor of Agronomy at the University of Florida Genetics Institute in Gainesville, FL. His research focuses on the genetic control of phenolic compounds that impact agro-industrial processing of crop plants. Ralph Nicholson is Professor of Botany and Plant Pathology at Purdue University in West Lafayette, IN. He is an expert on phenolic compounds involved in the plant’s defense against pathogenic fungi and bacteria.

Book Description
Phenolic compounds are produced by the plants mainly for their growth, development, and protection. These aromatic benzene ring compounds are very much essential during the plant,Äôs biotic and abiotic stress interactions. They constitute an essential part of plant,Äôs secondary metabolites and play a vital role in various physiological and mechanical activities. These diverse plant phenolic compounds act both as attractants and repellents toward various organisms in the environment. They could act as attractants toward the beneficial organisms and as toxicants against the invading pests and pathogens. These metabolite compounds often enhance during a plethora of stress conditions and act as the first line of defense to provide plant disease resistance. They are also known to influence the other plant metabolic pathways, namely phytoalexin biosynthesis and reactive oxygen species generation. These phenolic compounds participate both in the above- and below-ground plant defense systems. They are produced as root exudates and influence the soil diversity and the neighboring plants. The present review provides an overview of the roles of plant phenolic compounds in the plant kingdom as signaling compounds, pigment compounds, antimicrobials, and defense compounds.

Book Description
This work responds to the need to find, in a sole document, the affect of oxidative stress at different levels, as well as treatment with antioxidants to revert and diminish the damage. Oxidative Stress and Chronic Degenerative Diseases - a Role for Antioxidants is written for health professionals by researchers at diverse educative institutions (Mexico, Brazil, USA, Spain, Australia, and Slovenia). I would like to underscore that of the 19 chapters, 14 are by Mexican researchers, which demonstrates the commitment of Mexican institutions to academic life and to the prevention and treatment of chronic degenerative diseases.

Book Description
This book is a comprehensive collection of information on the role of plant phenolics in stress management in plants. The main focus of this book is to address the abiotic stress management in plants by plant phenolics under varied environments. Plant metabolic networks contribute significantly to the plasticity of plant metabolism, which is required to afford the sessile lifestyle of a land plant under changing environmental conditions. In natural systems, plants face a plethora of antagonists and thus possess a myriad of defenses and have evolved multiple defense mechanisms by which they can cope with various kinds of stresses for adaptation. Plant phenolics being ubiquitous have been extracted from every plant part such as roots, stem, leaves, flowers, fruits, and seeds and thus plays important role in adapting the plants to the varied environment. The book will provide readers with an up-to-date review of this dynamic field and sets the direction for future research. This book is of interest and use to a diverse range of topics of regulation of abiotic stress in plants. Bringing together work from leading international researchers, it is also a valuable reading material for plant and agricultural scientists, academics, researchers, students, and teachers wanting to gain insights into the role of plant phenolics in stress management in plants for sustainable agriculture.
