Plant Hormones in Crop Improvement examines the signaling pathways and mechanisms associated with phytohormones, with particular focus on stress resilience. The growing population of world and unpredictable climate puts pressure on the agriculture production. Current constraints such as increasing temperatures, drought, salinity, cold, nutrient deficiency, along with biotic interactions trigger exquisitely tuned responsive mechanisms in plants. The main coordinators of all stress-related mechanisms are phytohormones, which can be transported over long distances and play a significant role in controlling physiological, agronomic and growth traits, metabolites and sustained crop productivity. Therefore, understanding the mechanisms influencing the stress responses mediated by phytohormones is crucial to ensure the continuity of agricultural production and food security.?

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.

The present edited book is an attempt to update the state of art of the knowledge on metabolism of ROS and antioxidants and their relationship in plant adaptation to abiotic stresses involving physiological, biochemical and molecular processes. The chapters are much focused on the current climate issues and how ROS metabolism can manipulate with antioxidant system to accelerate detoxification mechanism. It will enhance the mechanistic understanding on ROS and antioxidants system and will pave the path for agricultural scientists in developing tolerant crops to achieve sustainability under the changing environmental conditions.The increase in abiotic stress factors has become a major threat to sustainability of crop production. This situation has led to think ways which can help to come out with potential measures; for which it is necessary to understand the influence of abiotic stress factors on crops performance and the mechanisms by which these factorsimpact plants. It has now become evident that abiotic stress impacts negatively on plant growth and development at every stage of plant’s life. Plants adapt to the changing environment with the adjustment at physiological, biochemical and molecular levels. The possible mechanisms involved in the negative effects of abiotic stress factors are excess production of reactive oxygen species (ROS). They alter physiological and molecular mechanisms leading to poor performance of plants. Plants however, are able to cope with these adverse effects by inducing antioxidant systems as the priority. Nevertheless, the dual role of ROS has now been ascertained which provides an evidence for regulation of plant metabolism positively on a concentration-dependent manner. Under conditions of high ROS production, the antioxidant system plays a major role in diminishing the effects of ROS. Thus, ROS production and antioxidant system are interwoven with abiotic stress conditions. The antioxidants have thecapacity to hold the stability in metabolism in order to avoid disruption due to environmental disturbances.
