This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Find out more on how to host your own Frontiers Research Topic or contribute to one as an author by contacting the Frontiers Editorial Office: frontiersin.org/about/contact

The effects of climate change on food safety and plant health represent a relatively new area of study. However, evidence from recent studies is clear: climate change contributes to increased and new food safety & plant health risks as one of several global change factors. This volume analyzes the scientific understanding of the relationship between climate change, food safety, plant pests, plant diseases, and trade. It identifies and discusses four key areas for future policy consideration: risk assessment, SPS capacity in developing countries, climate change resilience, and basic research challenges. We must effectively communicate the impacts of climate change on plant health and build the capacity of national plant protection organizations. More importantly, we need to mobilize resources that will help build stronger national phytosanitary systems that can prevent the spread of plant pests, thereby protecting our food sources and environment, and facilitating safe trade. The present volume is an asset for plant quarantine personnel working in the field, agricultural university students, plant health workers, farmers doing agriculture, plant & seed traders, and all those who use agricultural produce and products. The book is a useful resource for students and professional plant pathologists, entomologists, and plant breeders because it summarizes current knowledge and suggests new research directions. It is also suitable for ecologists & researchers working on crop protection, climate change, and pest control.

While the demand for crop products continues to increase strongly, agricultural productivity is threatened by various stress factors, often associated with global warming. To sustain and improve yield, it is necessary to understand how plants respond to various stresses, and to use the generated knowledge in modern breeding programs. Most knowledge regarding the molecular mechanisms associated with stress responses has been obtained from investigations using the model plant Arabidopsis thaliana. Stress hormones, such as abscisic acid, jasmonic acid, and salicylic acid, have been shown to play key roles in defense responses against abiotic and biotic stresses. More recently, evidence that growth-regulating plant hormones are also involved in stress responses has been accumulating. Epigenetic regulation at the DNA and histone level, and gene regulation by small non-coding RNAs appear to be important as well. Many approaches have used mutant screens and next generation sequencing approaches to identify key players and mechanisms how plants respond to their environment. However, it is often unclear to which extent the elucidated mechanisms also operate in crops. This Special Issue Book, therefore, aims to close this gap and contains a number of contributions from labs that work both, on Arabidopsis and crops. The book includes contributions reporting how crop plant species respond to various abiotic stresses, such as drought, heat, cold, flooding, and salinity, as well as biotic stimuli during microbial infections. It contains reviews, opinions, perspectives, and original articles, and its focus is on our molecular understanding of biotic and abiotic stress responses in crops, highlighting, among other aspects, the role of stress hormones, secondary metabolites, signaling mechanisms, and changes in gene expression patterns and their regulation. Approaches and ideas to achieve stress tolerance and to maintain yield stability of agricultural crops during stress periods can be found in most chapters. These include also perspectives on how knowledge from model plants can be utilized to facilitate crop-plant breeding and biotechnology.

This edited book deals with medicinal plants (herbs and trees) used in critical diseases which contain a rich resource of bioactive compounds that can be used as immuno-boosters or recommended for therapeutic values. Each chapter provides the basic information such as taxonomic description, occurrence and importance of medicinal plants. The detail description of major bioactive compounds in medicinal plants, their chemical nature and clear flow chart of biosynthesis are important steps in this book. This book also includes conservation strategy both in-situ and ex-situ, which assist the research and academic purpose. This book is of interest to national and international researchers, teacher’s, pharma scientists, and policymakers. Also, the book serves as additional reading material for both undergraduate and graduate students of pharma and agriculture in the world.

Plants possess a rather complex and efficient immune system. During their evolutionary history, plants have developed various defense strategies in order to recognize and distinguishing between self and non-self, and face pathogens and animal pests. Accordingly, to study the plant innate immunity represents a new frontier in the plant pathology and crop protection fields. This book is structured in 6 sections. The first part introduces some basic and general aspects of the plant innate immunity and crop protection. Sections 2–5 focus on fungal and oomycete diseases (section 2), bacterial and phytoplasma diseases (section 3), virus diseases (section 4), and insect pests (section 5), with a number of case studies and plant–pathogen/pest interactions. The last section deals with plant disease detection and control. The book aims to highlight new trends in these relevant areas of plant sciences, providing a global perspective that is useful for future and innovative ideas.
