Compensatory growth (CG) is defined as a change in growth rate (usually positive) following a period of reduced biomass or slowed growth due to some perturbation (e.g. nutrient deprivation, parasite load, tissue damage, or natural/anthropogenic disturbance). The phenomenon occurs throughout the plant and animal kingdoms, and while it is primarily observed in species with short lifespans, it has also been detected in longer-living organisms such as trees. CG occurs at the individual level as a variable life history trait but has the potential to impact the performance of whole populations and communities.

The global population is growing at an alarming rate and is anticipated to reach about 9.6 billion by the end of 2050. Addressing the problem of food scarcity for budding population vis-à-vis environmental changes is the main challenge plant biologists face in the contemporary era. Plant growth and productivity are scarce in many areas of the world due to a wide range of environmental stresses. The productive land is dwindling progressively by various natural and anthropogenic means that lead to enormous crop losses worldwide. Plants often experience these stresses and have the ability to withstand them. However, when the stress exceeds the normal tolerance level, plants accumulate organic osmolytes, osmoprotectants, cryoprotectants and antioxidant enzymes, which helps them tolerate these stresses and assist in their acclimatization towards the particular ambiance needed for maintaining their growth and development. Physiological Mechanisms and Adaptation Strategies in Plants Under Changing Environment, Volume 1 discuss drought and temperature stresses and their mitigation through different means. This volume illuminates how plants that are bombarded by diverse and changing environmental stimuli, undergo appropriate physiological alterations that enable their survival. The information covered in the book is also useful in building apposite strategies to counter abiotic and biotic stresses in plants. Written by a diverse group of internationally renowned scholars, Physiological Mechanisms and Adaptation Strategies in Plants Under Changing Environment, Volume 1 is a concise yet comprehensive resource that will be beneficial for the researchers, students, environmentalists and soil scientists of this field.

Leguminous crops have been found to contribute almost 27% of the world’s primary crop production. However, due to environmental fluctuations, legumes are often exposed to different environmental stresses, leading to problems with growth and development, and ultimately, decreased yield. This timely review explains the transcriptomics, proteomics, genomics, metabolomics, transgenomics, functional genomics and phenomics of a wide range of different leguminous crops under biotic and abiotic stresses, and their genetic and molecular responses. Amongst others the text describes the effect of nutrient deficiency, pesticides, salt, and temperature stress on legumes. Importantly, the book explores the physiobiochemical, molecular and omic approaches that are used to overcome biotic and abiotic constraints in legumes. It looks at the exogenous application of phytoprotectants; the role of nutrients in the alleviation of abiotic stress; and the microbial strategy for the improvement of legume production under hostile environments. Key features: demonstrates how to mitigate the negative effect of stress on leguminous crops, and how to improve the yield under stress the most up-to-date research in the field written by an international team of active researchers and practitioners across academia, industry and non-profit organisations. This volume is a valuable and much-needed resource for scientists, professionals and researchers working in plant science, breeding, food security, crop improvement and agriculture worldwide. In universities it will educate postgraduate and graduate students in plant science and agriculture; it will also benefit those in scientific institutions and in biotech and agribusiness companies, who deal with agronomy and environment.

Most organisms and populations have to cope with hostile environments, threatening their existence. Their ability to respond phenotypically and genetically to these challenges and to evolve adaptive mechanisms is, therefore, crucial. The contributions to this book aim at understanding, from a evolutionary perspective, the impact of stress on biological systems. Scientists, applying different approaches spanning from the molecular and the protein level to individuals, populations and ecosystems, explore how organisms adapt to extreme environments, how stress changes genetic structure and affects life histories, how organisms cope with thermal stress through acclimation, and how environmental and genetic stress induce fluctuating asymmetry, shape selection pressure and cause extinction of populations. Finally, it discusses the role of stress in evolutionary change, from stress induced mutations and selection to speciation and evolution at the geological time scale. The book contains reviews and novel scientific results on the subject. It will be of interest to both researchers and graduate students and may serve as a text for graduate courses.

This book sheds new light on the role of various environmental factors in regulating the metabolic adaptation of medicinal and aromatic plants. Many of the chapters present cutting-edge findings on the contamination of medicinal plants through horizontal transfer, as well as nanomaterials and the biosynthesis of pharmacologically active compounds. In addition, the book highlights the impacts of environmental factors (e.g., high and low temperature, climate change, global warming, UV irradiation, intense sunlight and shade, ozone, carbon dioxide, drought, salinity, nutrient deficiency, agrochemicals, waste, heavy metals, nanomaterials, weeds, pests and pathogen infections) on medicinal and aromatic plants, emphasizing secondary metabolisms. In recent years, interest has grown in the use of bioactive compounds from natural sources. Medicinal and aromatic plants constitute an important part of the natural environment and agro-ecosystems, and contain a wealth of chemical compounds known as secondary metabolites and including alkaloids, glycosides, essential oils and other miscellaneous active substances. These metabolites help plants cope with environmental and/or external stimuli in a rapid, reversible and ecologically meaningful manner. Additionally, environmental factors play a crucial role in regulating the metabolic yield of these biologically active molecules. Understanding how medicinal plants respond to environmental perturbations and climate change could open new frontiers in plant production and in agriculture, where successive innovation is urgently needed due to the looming challenges in connection with global food security and climate change. Readers will discover a range of revealing perspectives and the latest research on this vital topic.
