Abiotic Stress Physiology Of Horticultural Crops

This book brings together recent advances in the area of abiotic stress tolerance in various vegetables, fruit crops, plantation crops and tuber crops. The main challenges to improving the productivity of horticultural crops are the different types of abiotic stresses generally caused by climate change at the regional and global level. Heat, drought, cold and salinity are the major abiotic stresses that adversely affect growth and productivity and can trigger a series of morphological, physiological, biochemical and molecular changes in various horticultural crops. To date, there are no books covering horticultural crop-specific abiotic stress tolerance mechanisms and their management. Addressing that gap, the book is divided into 2 sections, the first of which highlights recent advances in the general aspects of abiotic stress tolerance like the role of hormones, reactive oxygen species, seed treatments, molecular mechanisms of heat tolerance and heavy metal toxicity, while the second focuses on the abiotic stress tolerance mechanisms of various vegetables, fruit crops, plantation crops and tuber crops. It includes comprehensive discussions of fruit crops like mango, grapes, banana, litchi and arid zone fruits; vegetables crops like tomato, capsicum, onion and tuber crops; and plantation crops like coconut, areca nut, oil palm and black pepper. Among the strategies for plant stress survival, examples of both avoidance and tolerance relevant to particular crops are examined in detail, supported by selected comprehensive case studies of progress. As such, the book offers a valuable resource suited for scientists and graduate students working in the fields of crop improvement, genetic engineering, and the abiotic stress tolerance of horticultural crops.

This book is a printed edition of the Special Issue Abiotic Stress Effects on Performance of Horticultural Crops that was published in Horticulturae

The purpose of this publication is to elucidate the biological aspect of the abiotic stress response from the field to the molecular level in horticultural plants. This book is unique in that it concerns the basic aspect of abiotic stress biology and research progress at the molecular level in model plants or major field crops, as it focuses mainly on the abiotic stress response in existing horticultural plants. Many readers interested in plant abiotic stress biology are aware of the application of the latest findings to agricultural production, and this book will have a special appeal for those readers. The book will be of interest to scientists and graduate students who are involved in the research, development, production, processing, and marketing of horticultural products, including those in developing countries who are interested in high tech and advanced science in this field. The application of the latest findings to agricultural production is particularly useful. Stress tolerance mechanisms in horticultural crops are gaining importance, because most agricultural regions are predicted to experience considerably more extreme environmental fluctuations due to global climate change. Further, because of recent progress in next-generation sequencing technologies, the postgenomic era is impending not only in model plants and major cereal crops but also in horticultural crops, which comprise a great diversity of species. This book provides information on the physiological aspects of the abiotic stress response in horticultural plants, which is considered essential for postgenomic research.

Stress Tolerance in Horticultural Crops: Challenges and Mitigation Strategies explores concepts, strategies and recent advancements in the area of abiotic stress tolerance in horticultural crops, highlighting the latest advances in molecular breeding, genome sequencing and functional genomics approaches. Further sections present specific insights on different aspects of abiotic stress tolerance from classical breeding, hybrid breeding, speed breeding, epigenetics, gene/quantitative trait loci (QTL) mapping, transgenics, physiological and biochemical approaches to OMICS approaches, including functional genomics, proteomics and genomics assisted breeding. Due to constantly changing environmental conditions, abiotic stress such as high temperature, salinity and drought are being understood as an imminent threat to horticultural crops, including their detrimental effects on plant growth, development, reproduction, and ultimately, on yield. This book offers a comprehensive resource on new developments that is ideal for anyone working in the field of abiotic stress management in horticultural crops, including researchers, students and educators. Describes advances in whole genome and next generation sequencing approaches for breeding climate smart horticultural crops Details advanced germplasm tolerance to abiotic stresses screened in the recent past and their performance Includes advancements in OMICS approaches in horticultural crops

Horticultural crop yield and quality depend on genotype, environmental conditions, and production management. In particular, adverse environmental conditions may greatly affect crop performance, reducing crop yield by 50%-70%. Abiotic stresses such as cold, heat, drought, flooding, salinity, nutrient deficiency, and ultraviolet radiation affect multiple physiological and biochemical mechanisms in plants as they attempt to cope with the stress conditions. However, different crop species can have different sensitivities or tolerances to specific abiotic stresses. Tolerant plants may activate different strategies to adapt to or avoid the negative effect of abiotic stresses. At the physiological level, photosynthetic activity and light-use efficiency of plants may be modulated to enhance tolerance against the stress. At the biochemical level, several antioxidant systems may be activated, and many enzymes may produce stress-related metabolites to help avoid cellular damage, including compounds such as proline, glycine betaine, and amino acids. Within each crop species there is a wide variability of tolerance to abiotic stresses, and some wild relatives may carry useful traits for enhancing the tolerance to abiotic stresses in their progeny through either traditional or biotechnological breeding. The research papers and reviews presented in this book provide an update of the scientific knowledge of crop interactions with abiotic stresses.

Plants often encounter abiotic stresses including drought, salinity, flooding, high/low temperatures, and metal toxicity, among others. The majority of these stresses occur simultaneously and thus limit crop production. Therefore, the need of the hour is to improve the abiotic stresses tolerance of crop plants by integrating physiology, omics, and modern breeding approaches. This book covers various aspects including (1) abiotic stress responses in plants and progress made so far in the allied areas for trait improvements, (2) integrates knowledge gained from basic physiology to advanced omics tools to assist new breeding technologies, and (3) discusses key genes, proteins, and metabolites or pathways for developing new crop varieties with improved tolerance traits.

This book deals with an array of topics in the broad area of abiotic stress responses in plants focusing “problems and their management” by selecting some of the widely investigated themes. Such as, Cell signalling in Plants during abiotic and biotic stress, Salinity stress induced metabolic changes and its management, High temperature stress: responses, mechanism and management, Low temperature stress induced changes in plants and their management, Biotechnological approaches to improve abiotic stress tolerance, Nutritional poverty in wheat under abiotic stress scenario, Strategies for improving soil health under current climate change scenario, Abiotic stress management in Pulse crops, Mitigation strategies of abiotic stress in fruit crops, Impacts of abiotic stress and possible management option in vegetable crops, and Abiotic stress: impact and management in ornamental crops. This book is useful for under-graduate and post-graduate students in Plant Physiology, Biochemistry, agronomy, horticulture, Botany, Environmental sciences and other cognate disciplines of agriculture and allied sciences and other research workers. We fervently believe that this book will provide good information and understanding of abiotic stress problems and their management in plants.

Abiotic stress includes not only single adversities, i.e., drought, salt, temperature, and elevated CO2, but also complex stresses, i.e., saline and alkali soil, and karst environment. Abiotic stresses strongly affect many aspects of a plant's substance and energy metabolism. Meanwhile, abiotic stress not only affects the physiological processes of photosynthesis, water metabolism, and inorganic nutrient absorption, but it also influences the electrophysiology and other physical parameters of plants. Plant physiological information, especially online physiological information, helps us to understand the plant's adaptive mechanism and take the effective measures to improve the production of horticultural plants. This Special Issue contains a collection of 11 important research works, which deepen the connotation and expand the denotation of plant physiology under abiotic stress. These works will provide a theoretical basis for the production of horticultural crops under single stresses, such as drought and salt stress, or under complex stresses, such as saline and alkali and karst environments. Readers from all over the globe are expected to greatly benefit from this Special Issue collection both in terms of their own work and to improve the productivity of horticultural crops under complex abiotic stresses. In the future, we hope that the field of plant (horticultural crop) physiology under abiotic stresses flourishes in terms of academic research and publications.
