Stomata, the tiny pores on leaf surface, are the gateways for CO2 uptake during photosynthesis as well as water loss in transpiration. Further, plants use stomatal closure as a defensive response, often triggered by elicitors, to prevent the entry of pathogens. The guard cells are popular model systems to study the signalling mechanism in plant cells. The messengers that mediate closure upon perception of elicitors or microbe associated molecular patterns (MAMPs) are quite similar to those during ABA effects. These components include reactive oxygen species (ROS), nitric oxide (NO), cytosolic pH and intracellular Ca2+. The main components are ROS, NO and cytosolic free Ca2+. The list extends to others, such as G-proteins, protein phosphatases, protein kinases, phospholipids and ion channels. The sequence of these signalling components and their interaction during stomatal signalling are complex and quite interesting. The present e-Book provides a set of authoritative articles from ‘Special Research Topic’ on selected areas of stomatal guard cells. In the first set of two articles, an overview of ABA and MAMPs as signals is presented. The next set of 4 articles, emphasize the role of ROS, NO, Ca2+ as well as pH, as secondary messengers. The next group of 3 articles highlight the recent advances on post-translational modification of guard cell proteins, with emphasis on 14-3-3 proteins and MAPK cascades. The last article described the method to isolate epidermis of grass species and monitor stomatal responses to different signals. Our e-Book is a valuable and excellent source of information for all those interested in guard cell function as well as signal transduction in plant cells.

Oxygen (O ) appeared in significant amounts in the Earth’s atmosphere over 2. 2 2 billion years ago, largely due to the evolution of photosynthesis by cyanobacteria (Halliwell 2006). The O molecule is a free radical, as it has two impaired electrons 2 that have the same spin quantum number. This spin restriction makes O prefer to 2 accept its electrons one at a time, leading to the generation of the so-called reactive oxygen species (ROS). The chemical nature of these species dictates that they can create damage in cells. This has contributed to the creation of the “oxidative stress” concept; in this view, ROS are unavoidable toxic products of O metabolism and 2 aerobic organisms have evolved antioxidant defences to protect against this tox- ity (Halliwell 1981; Fridovich 1998). Indeed, even in present-day plants, which are full of antioxidants, much of the protein synthetic activity of chloroplasts is used to replace oxidatively damaged D1 and other proteins (Halliwell 2006). Yet, the use of the “oxidative stress” term implies that ROS exert their effects through indiscriminate widespread inactivation of cellular functions. In this context, ROS must not be able to react with lipids, proteins or nucleic acids in order to avoid any damage to vital cellular components. However, genetic evidence has suggested that, in planta, purely physicoche- cal damage may be more limited than previously thought (Foyer and Noctor 2005).

Beyond the Visible: A handbook of best practice in plant UV photobiology presents methods for research on the responses of plants to ultraviolet (UV) radiation. The knowledge needed to make informed decisions about manipulation and quantification of UV radiation is summarized. Practical recommendations for obtaining reliable and relevant data and interpretations are given. The handbook covers research both on terrestrial and aquatic plants and it deals with experimentation on ecological, eco-physiological and physiological questions. The handbook includes 115 figures, mostly in colour, 19 tables and 12 text boxes. It is the result of the activities of COST action FA0906 "UV4growth", and it includes contributions by 17 authors. From the foreword by Dr. Marcel A. K. Jansen: This book ... is an important contribution towards such sound experimental design, promoting both "good practice" in UV-B manipulation, as well as "standardisation" of methodologies. Writing an authoritative book that will steer experimental approaches over the coming years, can not easily be done by an individual, but rather requires the concerted effort of a team of expert scientists. ... This is surely an excellent example of a concerted, Europeanwide activity that will boost the plant UV-B research field in Europe and beyond, for years to come.

Demonstrates how advances in plant chemical biology can translate to field applications With contributions from a team of leading researchers and pioneers in the field, this book explains how chemical biology is used as a tool to enhance our understanding of plant biology. Readers are introduced to a variety of chemical biology studies that have provided novel insights into plant physiology and plant cellular processes. Moreover, they will discover that chemical biology not only leads to a better understanding of the underlying mechanisms of plant biology, but also the development of practical applications. For example, the authors discuss small molecules that can be used to identify targets of herbicides and develop new herbicides and plant growth regulators. The book begins with a historical perspective on plant chemical biology. Next, the authors introduce the chemical biology toolbox needed to perform successful studies, with chapters covering: Sources of small molecules Identification of new chemical tools by high-throughput screening (HTS) Use of chemical biology to study plant physiology Use of chemical biology to study plant cellular processes Target identification Translation of plant chemical biology from the lab to the field Based on the latest findings and extensively referenced, the book explores available compound collections, principles of assay design, and the use of new research tools for the development of new applications. Plant Chemical Biology is recommended for students and professionals in all facets of plant biology, including molecular biology, physiology, biochemistry, agriculture, horticulture, and agronomy. All readers will discover new approaches that can lead to the development of a healthier and more plentiful global food supply.

This new edition of an established title examines the determination of grain crop yield from a unique perspective, by concentrating on the influence of the seed itself. As the food supply for an expanding world population is based on grain crops harvested for their seeds, understanding the process of seed growth and its regulation is crucial to our efforts to increase production and meet the needs of that population. Yield of grain crops is determined by their assimilatory processes such as photosynthesis and the biosynthetic processes in the seed, which are partly regulated within the seed itself. Substantially updated with new research and further developments of the practical applications of the concepts explored, this book is essential reading for those concerned with seed science and crop yield, including agronomists, crop physiologists, plant breeders, and extension workers. It is also a valuable source of information for lecturers and graduate students of agronomy and plant physiology.

Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.
