Plants are continuously exposed to different environmental stresses that negatively impact their physiology and morphology, resulting in production reduction. As a result of constant pressure, plants evolve different mechanisms for sustenance and survival. Hormones play a major role in defences against the stresses and stimulate regulatory mechanisms. One of the ways through which they mitigate stress is via the production of hormones like auxins, ethylene, jasmonic acid, etc. The phytohormones help in signaling and enhance the chances of their survival. Plant hormones play many vital roles from integrating developmental events, physiological and biochemical processes to mediating both abiotic and biotic stresses. This book aims to highlight these issues and provide scope for the development of tolerance in crops against abiotic stresses to maximize yield for the growing population. There is an urgent need for the development of strategies, methods and tools for the broad-spectrum tolerance in plants supporting sustainable crop production under hostile environmental conditions.
The salient features are as follows:
• It includes both traditional and non-traditional phytohormones and focuses on the latest progress emphasizing the roles of different hormones under abiotic stresses.
• It provides a scope of the best plausible and suitable options for overcoming these stresses and puts forward the methods for crop improvement.
• It is an amalgamation of the biosynthesis of phytohormones and also provides molecular intricacies and signalling mechanisms in different abiotic stresses.
• This book serves as a reference book for scientific investigators from recent graduates, academicians and researchers working on phytohormones and abiotic stresses.
Author Biography:
Dr Dhandapani Raju is a Senior Scientist of Plant Physiology in the Division of Physiology, Indian Agricultural Research Institute (ICAR-IARI), Delhi, India. He completed his under graduation in Agriculture from Tamil Nadu Agricultural University (TNAU), Tamil Nadu, India. He pursued his post-graduation in agriculture with a specialization in plant physiology from C. S. Azad University of Agriculture and Technology, Uttar Pradesh, India. He completed his doctoral degree in plant physiology from the Indian Agricultural Research Institute. He has been awarded “young scientist” by the Indian Society of Plant Physiology, New Delhi, India for his outstanding work on phenotyping banana fruits and identifying vitamin A enrichment gene (phytoene synthase gene) first time in bananas. His academic achievements are evident from possessing various awards, scholarships and merit medals (book prizes, ICAR-JRF, IARI-SRF & ICAR-ARS) at the national level during post-graduation education. He is the recipient of several best poster and oral presentation awards at the national level. Through agricultural research and development, he has invented five technologies, registered three international patents and published more than 15 peer-reviewed articles in both international and national journals of repute. He has currently working on high throughput phenotyping of rice plants for drought tolerance for the last four years. He has hands-on experience in the phenotyping of whole-plant transpiration and developed the software for automatic and near real-time estimation of WUE in rice. He has hands-on experience in both structural and functional genomics techniques for nucleic acid isolation, quality testing and gene expression analysis. He is also involved in teaching and guiding students at the post-graduation level. He has guided 09 MSc students to date. He has conducted three national-level trainings for professionals at state and central levels. Currently, he is working on a national-level multi-institutional project on plant phenomics to develop rice and wheat varieties with improved water use efficiency and nitrogen use efficiency.

She joined the Directorate of Maize Research (DMR), New Delhi (currently referred to as Indian Institute of Maize Research IIMR, Punjab, India) in 2009 till 2016 later she joined the Division of Genetics, IARI as a scientist in a senior scale in 2016. She has over fifteen years of research experience. She currently works in abiotic stress tolerance and doubled haploidy in soybeans. She worked in maize breeding for high oil along with baby corn. Her significant research includes heterotic grouping and patterning of quality protein maize using molecular markers, in vitro mutagenesis in rice and identification of sources of high oil post-Fusarium stalk rot resistance genetic stocks in maize and identification of tolerant sources for pre-germination anaerobic stress tolerance in soybean. She has edited two books namely “Genetics and Breeding in Pulses” and “Handbook of Cereals” and also served as an editor for a book on “Soybean”. She has many peer-reviewed research articles published in journals of international and national repute and book chapters to her credit. She is also serving as a reviewer in various national and international journals.
