Combined Stresses In Plants

The unique responses of plants to combined stresses have been observed at physiological, biochemical, and molecular levels. This book provides an analysis of all three levels of change in various plants in response to different combinations of stresses. The text provides a general review of the combined stress paradigm, focuses on the impact of higher CO2 levels in combination with other stresses, examines drought stress in conjunction with other abiotic factors in different crop plants as well as the combination of biotic and abiotic factors, and discusses the impact of combined stresses in forest ecosystems. Written by experts in the field, Combined Stresses in Plants: Physiological, Molecular, and Biochemical Aspects is a valuable resource for scientists, graduate students, and post-doctoral fellows alike working in plant stresses.

This book focuses on multiple plant stresses and the molecular basis of adaptation, addressing the molecular mechanism and adaptation for both abiotic and biotic stresses. Ensuring the yield of crop plants grown under multiple individual and/or combined stresses is essential to sustaining productivity. In this regard, the development of broad-spectrum stress-tolerant plants is important. However, to date information has largely been compiled only on the individual stress tolerance mechanisms, and the mechanisms behind plants’ tolerance to two or more individual or simultaneous stresses are not fully understood. Especially combinatorial stress, a new stress altogether, has only recently been made the object of systematic study. Now several research groups around the world have begun exploring the concurrent stress tolerance mechanisms under both biotic and abiotic stress combinations. This book presents contributions from various experts, highlighting the findings of their multiple individual and concurrent stress tolerance dissection studies.

In the last 50 years, classical breeding has played a significant role in achieving higher crop productivity, but major crops have reached a plateau in their yield potential. Therefore, the current focus for sustainable intensification of agriculture is the use of biotechnological approaches to enhance the yield potential by combating the yield losses that occur due to abiotic stresses. The abiotic stresses are governed by multigenes, and therefore, a holistic approach is needed to get success in imparting stress tolerance to enhance the yield potential of our crops. Plants face multiple stress conditions during their life stages and adopt several physiological, biochemical, and molecular strategies to combat that, which are sometimes not sufficient to survive, particularly crop plants. The climate change era has created a need to understand the abiotic stresses in a holistic way. Therefore, a deep understanding of multiple abiotic stress mechanisms is necessary to develop crops tolerant to climate fluctuation. With this background, the outline of this book covers the following features: • Agriculture sustainability and molecular understanding of multiple stress tolerance • Systems biology for life-history strategies, conventional and genomic approaches above and underground • Genetic resources and molecular understanding of seed priming • Molecular signaling compounds, cell signal transduction, and crosstalk between plant growth hormones and regulators • Roles Transcription factors, LEA proteins, reactive oxygen species and alternative oxidase • Genome editing, metabolomics, and ‘omics’ technologies

Climate change has caused fluctuations in the frequency and severity of droughts and floods, favoring extended periods of drought and extreme rainfall, rises in temperature, and associated with anthropic actions, has triggered other stressful abiotic effects, which have threatened terrestrial ecosystems and, especially agroecosystems. Considering the current environmental scenario, studies related to cultural practices with native or cultivated species have been carried out with the aim of guaranteeing sustainable development, conservation of biodiversity and natural resources, and the guarantee of food sovereignty.

Facing stressful conditions imposed by their environment and affecting their growth and their development throughout their life cycle, plants must be able to perceive, to process and to translate different stimuli into adaptive responses. Understanding the organism-coordinated responses involves a fine description of the mechanisms occurring at the cellular and molecular level. A major challenge is also to understand how the large diversity of molecules identified as signals, sensors or effectors could drive a cell to the appropriate plant response and to finally cope with various environmental cues. In this Research Topic we aim to provide an overview of various signaling mechanisms or to present new molecular signals involved in stress response and to demonstrate how basic/fundamental research on cell signaling will help to understand stress responses at the whole plant level.

A close examination of current research on abiotic stresses in various plant species The unpredictable environmental stress conditions associated with climate change are significant challenges to global food security, crop productivity, and agricultural sustainability. Rapid population growth and diminishing resources necessitate the development of crops that can adapt to environmental extremities. Although significant advancements have been made in developing plants through improved crop breeding practices and genetic manipulation, further research is necessary to understand how genes and metabolites for stress tolerance are modulated, and how cross-talk and regulators can be tuned to achieve stress tolerance. Molecular Plant Abiotic Stress: Biology and Biotechnology is an extensive investigation of the various forms of abiotic stresses encountered in plants, and susceptibility or tolerance mechanisms found in different plant species. In-depth examination of morphological, anatomical, biochemical, molecular and gene expression levels enables plant scientists to identify the different pathways and signaling cascades involved in stress response.
