Maximising the Use of Biological Nitrogen Fixation in Agriculture
Incorporating contributions from microbiologists, molecular biologists, plant breeders and soil scientists this volume reports the results and recommendations of an FAO/IAEA meeting of twelve experts on biological nitrogen fixation. This volume will be invaluable to scientists working on nitrogen fixation, soil microbiology, agronomy and crop production as well as farm advisers and extension specialists. Maximising the Use of Biological Nitrogen Fixation in Agriculture is unique in that it: -reviews the latest thinking on various aspects of biological nitrogen fixation technology and applications; -reviews the possibilities in enhancing nitrogen fixation in various cropping systems; -shows ways how biological nitrogen fixation can be used to enhance crop production; -considers the applicability of these technologies to small farmers in developing countries.
Constitutions and Gender
Constitutions and gender is a new and exciting field, attracting scholarly attention and influencing practice around the world. This timely handbook features contributions from leading pioneers and younger scholars, applying a gendered lens to constitution-making and design, constitutional practice and citizenship, and constitutional challenges to gender equality rights and values. It offers a gendered perspective on the constitutional text and record of multiple jurisdictions, from the long-established, to the world’s newly emerging democracies. Constitutions and Gender portrays a profound shift in our understanding of what constitutions stand for and what they do.
Lipid Metabolism and human diseases
Lipids such as cholesterol, phospholipids, triglycerides, and free fatty acids, play various essential physiological roles. Dysregulation of lipid metabolism causes dyslipidemia, which is a critical factor in the development of various human diseases, such as cardiovascular disease, diabetes, non-alcoholic fatty liver disease, Alzheimer's disease, and Niemann-Pick disease. Therefore, lipid homeostasis in humans is strictly regulated by a well-balanced mechanism of intestinal uptake, endogenous synthesis and metabolism, and transport in lipoprotein particles and excretion. The human body evolves multiple mechanisms to maintain lipid homeostasis, such as low-density lipoprotein receptor mediates clearance of circulating low-density lipoprotein cholesterol; phospholipid transfer protein mediates the transfer of phospholipids from apoB-containing triglyceride-rich lipoprotein to high-density lipoprotein, etc.
Root Hairs
Root hairs are tip-growing cells that originate from epidennal cells called trichoblasts. Their role may be simply thought of as extending the surface area of the root to facilitate absorption of nutrients and water. However, as you will see in this book, the root hair is far more than that. To an increasingly larger number of plant biologists, the root hair is a model cell. It grows in much the same way as a pollen tube, by sending vast numbers of vesicles containing cell wall precursors to a rounded apical dome, the tip. Once the trichoblast becomes committed to root hair fonnation, it no longer divides. The root hair cell has a migrating nucleus and a complex cytoskeleton. It has a varied...
Plant Signaling Peptides
Plants have evolved with a complex array of signaling molecules to facilitate their growth and development and their interactions with the environment. A vast number of different peptide molecules form an important but until recently often overlooked component amongst these signaling molecules. Plant peptide signals are involved in regulating meristem growth and organogenesis, modulating plant growth and homeostatic responses. They also have important roles as signals of imminent danger or pathogen attack. This volume focuses on the roles of various peptide signaling molecules in development, defence and homeostasis. As it is likely that further plant peptide signaling molecules remain to be discovered, the last section takes a practical look at methods to identify new peptides and characterise their functions.
