Sustainable Plant Nutrition: Molecular Interventions and Advancements for Crop Improvement explores the significant opportunities for sustainable, eco-friendly approaches in plant nutrition and agricultural crop production. The book highlights the various prospects involved in optimizing plant nutrient uptake agriculture and includes chapters representing diverse areas dealing with biotechnology, nanotechnology, molecular biology, proteomics, genomics and metabolomics. This book is an ideal resource for those seeking to ensure a sustainable plant production future. While plants have evolved a set of elaborate mechanisms to cope with nutrient limitations, the traditional supplementation by the application of fertilizers to plant productivity may then lead to overfertilization which can actually reduce plant growth and have adverse effects on the environment. To tackle these issues, a detailed understanding of the responses of plants to nutrients and nutrient deficiency at the physiological, metabolic, transcriptome and epigenetic level is essential.

This open access book is only an introduction to show that radiation and radioisotopes (RI) are premier tools to study living plant physiology which leads to new findings. Who had ever imagined that we could see water in a plant? Who had ever imagined that we could see ions moving toward roots in solution? Who had ever imagined that we could see invisible gas (CO2) fixation and movement in a plant? These studies demonstrated for the first time that water, ions and gas can be visualized in living plants, which could be hardly seen by anyone before. This publication summarizes the results obtained by Nakanishi's lab in The Univ. of Tokyo, based on her original concept and her original tools or systems. It is useful for professional scientists, plant physiologist, and those studying plant imaging. The chapters demonstrates the innovative imaging work of the author, using radioactive tracers and neutron beam to follow the absorption and transport manner of water as well as major, minor, and trace elements in plants. Through these studies the author developed a real-time macroscopic and microscopic imaging system able to apply commercially available gamma- and beta-ray emitters. The real-time movement of the elements is now possible by using 14C, 18F, 22Na, 28Mg, 32P, 33P, 35S, 42K, 45Ca, 48V, 54Mn, 55Fe, 59Fe, 65Zn, 86Rb, 109Cd, and 137Cs. The imaging methods was applied to study the effect of 137Cs following 3/11 Fukushima Daiichi nuclear plant accident, which has revealed the movements of radiocesium in the contaminated sites.

Plant organelles have intrigued biologists since the discovery of their endosymbiontic origin and maternal inheritance. The first application of organelle biotechnology was the role of cytoplasmic male sterility in hybrid seed production and "Green Revolution." In modern times, plant organelles are again leading the way for the creation of genetically modified crops. On a global scale, 75% of GM crops are engineered for herbicide resistance and most of these herbicides target pathways that reside within plastids. Several thousand proteins are imported into chloroplasts that participate in biosynthesis of fatty acids, amino acids, pigments, nucleotides and numerous metabolic pathways including photosynthesis. Thus, from green revolution to golden rice, plant organelles have played a critical role in revolutionizing agriculture.

This book details not only basic concepts and current understanding of plant organelle genetics and molecular biology but also focuses on the synergy between basic biology and biotechnology. Forty four authors from nine countries have contributed twenty four chapters containing many figures and tables. Section 1 on organelle genomes and proteomes discusses molecular features of plastid and mitochondrial genomes, evolutinary origins, somatic and sexual inheritance, proteomics, bioinformatics and functional genomics. Section 2 on organelle gene expression and signalling discusses transcription, translation, RNA processing/editing, introns and splicing, protein synthesis, proteolysis, import of proteins into chloroplast and mitochondria and their regulation. Section 3 on organelle biotechnology discusses chloroplast and nuclear genetic engineering forbiotic/abiotic stress tolerance, improved fatty acid/amino acid biosynthesis, biopharmaceuticals, biopolymers and biomaterials, cytoplasmic male sterility for hybrid seed production, plant improvement and restoration of fertility.

Medicinal plants are globally valuable sources of herbal products. Plant-based remedies have been used for centuries and have had no alternative in the western medicine repertoire, while others and their bioactive derivatives are in high demand and have been the central focus of biomedical research. As Medicinal plants move from fringe to mainstream with a greater number of individuals seeking treatments free of side effects, considerable attention has been paid to utilize plant-based products for the prevention and cure of human diseases. An unintended consequence of this increased demand, however, is that the existence of many medicinal plants is now threatened, due to their small population size, narrow distribution area, habitat specificity, and destructive mode of harvesting. In addition, climate change, habitat loss and genetic drift have further endangered these unique species. Although extensive research has been carried out on medicinal and aromatic plants, there is relatively little information available on their global distribution patterns, conservation and the associated laws prevailing. This book reviews the current status of threatened medicinal plants in light of increased surge in the demand for herbal medicine. It brings together chapters on both wild (non-cultivated) and domestic (cultivated) species having therapeutic values. Thematically, conventional and contemporary approaches to conservation of such threatened medicinal plants with commercial feasibility are presented. The topics of interest include, but not limited to, biotechnology, sustainable development, in situ and ex situ conservation, and even the relevance of IPR on threatened medicinal plants. We believe this book is useful to horticulturists, botanists, policy makers, conservationists, NGOs and researchers in the academia and the industry sectors.

The roles of developmental and genetic responses in determining photosynthetic performance are also considered. The complexity of the responses to environmental change is demonstrated by detailed analyses of the effects of specific environmental variables (light, temperature, water, CO2, ozone and UV-B) on photosynthetic performance. Where appropriate attention is given to recent developments in the techniques used for studying photosynthetic activities.

The book is intended for advanced undergraduate and graduate students and a wide range of scientists with research interests in environmental effects on photosynthesis and plant productivity.

Jatropha curcas, or physic nut, is a small tree that, in tropical climates, produces fruits with seeds containing ~38% oil. The physic nut has the potential to be highly productive and is amenable to subculture in vitro and to genetic modification. It also displays remarkable diversity and is relatively easy to cross hybridize within the genus. Thanks to these promising features, J. curcas is emerging as a promising oil crop and is gaining commercial interest among the biofuel research communities. However, as a crop, physic nut has been an economic flop since 2012, because the species was not fully domesticated and the average productivity was less than 2 t/ha, which is below the threshold of profitability.^7 t/ha could be reached and it is contributing to new markets in some countries. As such, it is important fro research to focus on the physiology and selective breeding of Jatropha . This book provides a positive global update on Jatropha, a crop that has suffered despite its promising agronomic and economic potential. The editors have used their collective expertise in agronomy, botany, selective breeding, biotechnology, genomics and bioinformatics to seek out high-quality contributions that address the bottleneck features in order to improve the economic trajectory of physic nut breeding.

Global population is mounting at an alarming stride to surpass 9.3 billion by 2050, whereas simultaneously the agricultural productivity is gravely affected by climate changes resulting in increased biotic and abiotic stresses. The genus Brassica belongs to the mustard family whose members are known as cruciferous vegetables, cabbages or mustard plants. Rapeseed-mustard is world's third most important source of edible oil after soybean and oil palm. It has worldwide acceptance owing to its rare combination of health promoting factors. It has very low levels of saturated fatty acids which make it the healthiest edible oil that is commonly available. Apart from this, it is rich in antioxidants by virtue of tocopherols and phytosterols presence in the oil. The high omega 3 content reduces the risk of atherosclerosis/heart attack. Conventional breeding methods have met with limited success in Brassica because yield and stress resilience are polygenic traits and are greatly influenced by environment. Therefore, it is imperative to accelerate the efforts to unravel the biochemical, physiological and molecular mechanisms underlying yield, quality and tolerance towards biotic and abiotic stresses in Brassica. To exploit its fullest potential, systematic efforts are needed to unlock the genetic information for new germplasms that tolerate initial and terminal state heat coupled with moisture stress. For instance, wild relatives may be exploited in developing introgressed and resynthesized lines with desirable attributes. Exploitation of heterosis is another important area which can be achieved by introducing transgenics to raise stable CMS lines. Doubled haploid breeding and marker assisted selection should be employed along with conventional breeding. Breeding programmes aim at enhancing resource use efficiency, especially nutrient and water as well as adoption to aberrant environmental changes should also be considered. Biotechnological interventions are essential for altering the biosynthetic pathways for developing high oleic and low linolenic lines. Accordingly, tools such as microspore and ovule culture, embryo rescue, isolation of trait specific genes especially for aphid, Sclerotinia and alternaria blight resistance, etc. along with identification of potential lines based on genetic diversity can assist ongoing breeding programmes. In this book, we highlight the recent molecular, genetic and genomic interventions made to achieve crop improvement in terms of yield increase, quality and stress tolerance in Brassica, with a special emphasis in Rapeseed-mustard.

This book summarizes the latest studies on plant reproduction and multiple aspects of signaling in reproductive development. It also presents the most advanced processes in CrRLK1L receptor and RALF peptide studies during plant development. Focusing on signaling in pollen tube integrity and sperm release regulation, it provides significant insights into the BUPS-ANX receptor complex and the corresponding ligands RALF4/19 to promote pollen tube growth with proper cell integrity.

Salinity is one of the acute problems causing enormous yield loss in many regions of the world. This phenomenon is particularly pronounced in arid and semiarid regions. Halophytes can remove salt from various types of problematic soils due to their unique morphological, physiological and anatomical adaptations to these environments. Halophytes are also used for the treatment of certain diseases but scientific documentation in terms of current phytotherapic applications is deficient in this unique group of plants. Different ethnic groups around the world use medicinal halophytes according to their own beliefs and ancestor’s experiences. However, their knowledge about the use of salt tolerant medicinal plants is usually confined to their own community. There is thus a knowledge gap on halophytes which should be bridged and preserved. This book provides a comprehensive account on the distribution of halophytes, their ethnobotanical and medicinal aspects, economic importance, and chemical constituents along with scientific description. The book therefore serves as a valuable resource for professionals and researchers working in the fields of plant stress biology and ethnobotanical aspects.
