Plants require nutrients in order to grow, develop and complete their life cycle. Mineral fertilizers, and hence the fertilizer industry, constitute one of the most imp- tant keys to the world food supplies. There is growing concern about the safety and quality of food. Carbon, hydrogen and oxygen, which, together with nitrogen, form the structural matter in plants, are freely available from air and water. Nitrogen, phosphorus and potassium, on the other hand, may not be present in quantities or forms sufficient to support plant growth. In this case, the absence of these nut- ents constitutes a limiting factor. The supply of nutrients to the plants should be balanced in order to maximise the efficiency of the individual nutrients so that these meet the needs of the particular crop and soil type. For example, it should be noted that EU-wide regulations are not designed to govern the specific details of mineral fertilizer use. Although plants receive a natural supply of nitrogen, phosphorus and potassium from organic matter and soil minerals, this is not usually sufficient to satisfy the demands of crop plants. The supply of nutrients must therefore be supplemented with fertilizers, both to meet the requirements of crops during periods of plant growth and to replenish soil reserves after the crop has been harvested. Pesticides are important in modern farming and will remain indispensable for the foreseeable future.

The plant physiology and plant molecular biology research group has evidently endorsed the new directions taken by the treatise to attract the pre-eminent scientists in plant biology/plant sciences. Certainly, the preparation of Volume 13 of the International Treatise Series on Advances in Plant Physiology has been done entirely due to commendable contributions from Scientists of Eminence in unequivocal fields. Unquestionably, our objective is to publish innovative science of value across the broad disciplinary range of the treatise. I restate that this plan has been undertaken with a view to strengthen the indistinguishable efforts to recognize the outcome of meticulous research in some of the very sensible and stirring areas of Plant Physiology-Plant Molecular Physiology/ Biology-Plant Biochemistry for holistic development of the science of agriculture and crop production under changing climate. I am ardent to keep on the exceptionality and the prologue of excellent new ideas ensuring that the treatise calls to the best science done across the full extent of modern plant biology, in general, and plant physiology, in particular. In Volume 13, with inventive applied research, attempts have been made to bring together much needed eighteen review articles by forty-eight contributors especially from premier institutions of India for this volume. All the eighteen review articles have been grouped in five broad sections, which on the whole highlight the necessity to find out evidence from the fields of plant nutriophysiology (physiology of plant mineral nutrients) and abiotic stresses under changing climate along with their control.

Global climate change is one of the most serious and pressing issues facing our planet. Rather than a “silver bullet” or a single study that solves it, the study of global climate change is like a beach, with each contribution a grain of sand, gathered together as a whole to create a big picture, moving the science forward. This new groundbreaking study focuses on the adaptation and tolerance of plants and animal life to the harsh conditions brought on by climate change or global warming. Using the papers collected here, scientists can better understand global climate change, its causes, results, and, ultimately, the future of life on our planet. The first section lays out a methodology and conceptual direction of the work as a whole, covering the modeling, approaches, and the impacts studied throughout the book. The second section focuses on certain hypotheses laid out by the authors regarding how plants and animal life can adapt and survive in extreme environments. The third section compiles a series of ecological experiments and their conclusions, and a final section is dedicated to previous scientific breakthroughs in this field and the scientists who made them. Whether for the scientist in the field, the student, or as a reference, this groundbreaking new work is a must-have. Focusing on a small part of the global climate change “beach,” this “grain of sand” is an extremely important contribution to the scientific literature and a step forward in understanding the problems and potentialities of the issue.
