Prof. Jitendra Paul Khurana (30 October 1954 to 27 October 2021)
Prof. Jitendra Paul Khurana was an Indian botanist known for his contributions to the fields of plant molecular biology. He obtained a PhD in Botany from the University of Delhi in 1982 and did postdoctoral work at the prestigious Smithsonian Institution, Washington, DC (1985–1986) and the Michigan State University, USA (1986–1988). He was a visiting professor at the USDA, Beltsville, between 1996 and 1998, and at the Waksman Institute of Microbiology, Rutgers University, USA, in 2001. He was a founder faculty member of the Department of Plant Molecular Biology, University of Delhi South Campus. He was a J.C. Bose National Fellow of SERB at the University of Delhi South Campus. He was the Vice President of the Indian National Science Academy (INSA) for International Affairs. Prof. Khurana was Pro-Vice Chancellor (Interim), University of Delhi, and Director, University of Delhi South Campus, for over three years (2016–2019); he also had additional charge as Dean (Colleges).
Prof. Khurana’s work on Arabidopsis mutants led to the identification of a novel blue light receptor, phytotropin 1, which primarily controls phototropism and leaf orientation to capture maximal solar energy for photosynthesis. Recently, his group has demonstrated the role of other blue light receptors, cryptochrome 1 (CRY1), in controlling plant height in mustard and CRY2 in regulating flowering time in both mustard and rice. He played a key role in sequencing of rice, tomato, and wheat genomes as part of the International Consortia. Using in-house expertise, they provided evidence for bZIP and F-box proteincoding genes in regulating light, hormone, and stress signaling leading to panicle and seed development. OsbZIP62 serves as Flowering Locus D (FD), preferentially expressing in the shoot apical meristem, and interacts with the mobile flowering signal “florigen” (FT) to regulate the transition to flowering and panicle development in rice. His recent work stressed on the role of the bZIP and F-box proteins in abiotic stress responses and the interplay of light and environmental stress in plant development. His work is documented in over 200 publications. Professor Khurana was the elected Fellow of all the National Science Academies (INSA, IASc, NASI, and NAAS) and the World Academy of Sciences (TWAS), Trieste, Italy. His other honors and awards include the Tata Innovation Fellowship (2010–2013) by the DBT, “J.C. Bose National Fellowship” by the DST-SERB (2013 onward), Birbal Sahni Medal by the Indian Botanical Society (2011), “Goyal Prize” in Life Sciences (2017) by the Goyal Foundation, Shri Om Prakash Bhasin Award in Biotechnology (2017), and Jawaharlal Nehru Birth Centenary Visiting Fellowship (2019) by INSA, to name a few.
This book is dedicated to the memory of Prof. Jitendra P. Khurana as a token of our appreciation and respect for him and his achievements.

Foreword
I am overjoyed to write about this book, Global Climate Change and Plant Stress Management, which symbolizes a comprehensive and current exchange on the newest insights into the improvement of crops under climate change and plant stress management. At the present time, the global climate change (see, e.g. The Discovery of Global Warming by Spencer R, Weart, 2008, Harvard University Press) and the population increase are two important restrictions before us, and dealing with these crucial issues is of paramount importance in the field of agriculture. This book deals with a subject of enormous significance not only for plant scientists but also for farmers worldwide. Research on exploring diverse aspects of an easy, money-making, and ecologically oriented practice of pre-soaking seeds in salt solutions (what one calls “halo priming”) seems desirable, as it might aid in sustaining agricultural production in our changing environment. The recent trend in climate change involving high salinity, increased temperature, draught, and heavy metal toxicity, as well as negative effects of bacterial, viral, and fungal diseases and insect infestation have gloomy effects on agriculture productivity. To add to this, predicted increase in CO2, with ocean acidification, is expected to cause a drastic decline in global agriculture productivity. All of this will have a considerable harmful impact on our ecosystem. Thus, this particular volume, which deals with various aspects of plant stress physiology, together with plant stress responses, and physiological and molecular mechanism of plant tolerance to environmental stresses, is particularly welcome. It goes a long way toward finding ways to overcome the gloomy predictions before us.
On a positive note, the potential function of several important genes and, thus, the proteins that they code for, as well as a range of signaling molecules, such as plant hormones, that regulate plant growth and developmental processes, is now available. The above was possible because of detailed studies on responses of tolerant and susceptible agriculturally important crops to climate change from both physiological and biotechnological points of view. On the other hand, developing climate- smart varieties through mutation breeding involving modification of a single gene rather than altering the whole genome is an attractive goal. Recent development in science relies on ‘Omics’ tools, such as genomics, transcriptomics, epigenomics, proteomics, metabolomics, and phenomics, and this is indeed being actively pursued at many institutions around the world. In addition, CRISPR/Cas techniques provide precision and rapidity to breeding programs to develop smart and nutrition crops in changing environment, which might be a key solution for ensuring food security.
The compilation of a comprehensive volume on this very important and challenging topic has been achieved in the current book entitled Global Climate Change and Plant Stress Management, edited by Mohammad Wahid Ansari, Anil Kumar Singh, and Narendra Tuteja; it is both commanding and timely. This book also emphasizes the effect of climate change studies on plant metabolism and adaptive characteristics; it is an up-to-date compilation for the benefit of researchers and academicians. In this book, authors introduce and classify climate change conditions as well as various stress components and then present a detailed discussion related to their effects on plant development, controlling factors of their biome, as well as the behavior of plants under climate change conditions and the associated adverse effects. This book also covers the new emerging technical concepts of stress management, which is an advanced concept to sustain agricultural productivity under recent climatic scenarios. Further, this book provides instant access to comprehensive, cutting-edge data, making it possible for plant scientists and others to utilize this ever-growing wealth of information. I strongly believe that this book provides a great deal of global implications not only for food security but also for the socioeconomic condition of communities affected by climate change worldwide. In addition, the knowledge presented in this book is expected to be of great benefit to the farmers, who can understand and exploit the useful crops as per the nature of the climate and benefit from it
for public and private investment. The current insightful book is expected to provide key information, in an excellent manner, to students, postdoctoral fellows, plant scientists, and policymakers on what actions to take on plant stress management under the expected climate change. I am quite confident that this book will be read, understood, and exploited extensively.
I heartily appreciate the efforts of all the contributing 80 authors from 12 different countries – Australia, England, Fiji Island, Italy, India, Iran, Japan, Kingdom of Saudi Arabia, Nepal, South America, and the United Kingdom, and all the outstanding editors for this well-timed and enlightening publication on the important topic of the effects of global climate change on plants and what to do to alleviate its negative impact.

Preface
The existence of living organisms depends on the food synthesized by mainly green plants by capturing energy from sunlight through the process of photosynthesis. At present, a global challenge is to sustain crop productivity in a changing environment to meet the demand of increasing population. However, the current reports of the Intergovernmental Panel on Climate Change have made clear that the urgency to take action on global climate change and agrifood production is not well understood so far. There is an urgent need for agrifood systems to be more versatile to the existing and upcoming impacts of global climate change, which could be achieved through learning from superior practices, encouraging transformative adjustment strategies, plans, and its subsequent actions. A growing tendency toward climate change for the past few decades has badly hit global crop production on the large scale. It imposes environmental variations that include high salinity, very high and low temperatures, draughts, heavy metal toxicity and nutrient loss, the growth of bacteria, viruses, fungi, different pests, and parasites, harmful insect invasions, and increased CO2 and ocean acidification. This will have a considerably harmful impact on beneficial microbes, plant productivity, restoration efforts, and ecosystem health. Global warming is expected to elicit harsh weather trends, long-lasting droughts, floods and waterlogging, storms, and increased disease incidence, which cause altered growth, impaired photosynthesis, and reduced physiological responses in plants that limit agrifood production. Global sustainable farming systems are at risk owing to rising and co-occurring temperatures, droughts, and salinity stresses. According to a new report from the World Meteorological Organization (WMO), the impact of water stress and drought hazards, including withering droughts and overwhelming floods, is thrashing African communities and ecosystems. The strategies to deal with increased CO2 concentrations and global warming and enhance plant tolerance to abiotic and biotic stresses are important targets for sustainable agricultural production. Recent advances in science, such as CRISPR-associated (Cas) protein-based genome editing (CRISPR- Cas) and “Omics” tools such as genomics, transcriptomics, epigenomics, proteomics, metabolomics, and phenomics, have enhanced precision and rapidity in the progress of plant molecular breeding programs to develop nutrient-enriched and stress-tolerant plant variety, which might be the key players in ensuring food security. Additionally, it will contribute a significant amount of potential for developing more resilient and climate-smart crops to respond to the rising threat of climate change and its undesirable effects on agrifood.
In the present book, Global Climate Change and Plant Stress Management, we present a collection of 27 chapters by 80 experts from 12 different countries – Australia, England, Fiji Island, Italy, India, Iran, Japan, Kingdom of Saudi Arabia, Nepal, South America, and the United Kingdom. This book offers a current overview of recent developments in sustainable agriculture production in a changing environment. This book aims to accentuate issues of global climate change and food insecurity for billions of people, assuming they will face drastic hunger in the upcoming period. It emphasizes all concerns about carbon and nutrient cycles, global warming, and environmental stresses originating under a scenario of global climate change and thereby badly affecting basic agriculture production, on which the common world’s poor depend. This book also presents the potential ways of exploring, investigating, and adopting novel techniques and tools, methodologies, and scientific inventions to realize climate’s outcomes on food security. The knowledge convened herein might be inspiring to farmers who may respond to beneficial crops as per the foretold climate. This perceptive will result in good dealings for both scientists indicted for predicting global climate threats and policymakers responsible for influential decisions in the field. The present book is specifically appropriate for environmental and biological science students engaged in interdisciplinary research, research scholars, young scientists, and faculty members. We thank the late Prof. R.C. Pant and Dr. Alok Shukla who helped us during the initial phase of this work.
