  • Publisher: Elsevier

Plant RNA Viruses: Molecular Pathogenesis and Management provides wide-ranging coverage on the recognition and signaling events between plants and RNA viruses. The book examines the molecular biology of signaling, host-virus interaction, RNA virus diversity, and how plants and cellular pathogens interact. Sections cover Virus Diversity and Diagnosis, Virus-Host Interactions and Virus Management. Specific chapters discuss classification and nomenclature of viruses, detail the molecular characteristics of viral genomes, highlight the viral manipulation of cellular key regulatory systems for successful virus infection, and discuss the movement of plant viruses into plant cells. Additional topic...

Climate Change Adaptation Strategies in Agriculture and Allied Sectors

Weather related disasters like occurrence of floods, droughts, heat wave and cold waves is not uncommon across the Country. It is true world over. Increase in sea surface temperature and sea level has potential impact on monsoon uncertainties, water resources, shift in coastal population and marine products. Vulnerability to extreme weather events is higher than vulnerability to changing average climatic conditions. The society linked sectors like agriculture, biodiversity, fisheries, forestry, water resources, human and animal health and infrastructure are the worst sufferers in the event of weather uncertainties. As a result it is realized that food security is under threat due to global w...

  • Publisher: Springer

This book focuses on the evolution of plant viruses, their molecular classification, epidemics and management, covering topics relating to evolutionary mechanisms, viral ecology and emergence, appropriate analysis methods, and the role of evolution in taxonomy. The currently emerging virus species are increasingly becoming a threat to our way of life, both economically and physically. Plant viruses are particularly significant as they affect our food supply and are capable of rapidly spreading to new plant species. In basic research, plant viruses have become useful models to analyze the molecular biology of plant gene regulation and cell-cell communication. The small size of DNA genome of v...

Genetic Sex Differentiation in Fish

  • Publisher: CRC Press

A comprehensive study of sex differentiation gonochoric and hermaphroditic fishes, this book examines sex chromosomes and sex determining genes, emphasizing the need to search for more than one sex-determining gene residing on different chromosomes. It traces the origin of hermaphrodites from secondary gonochores and explains the conservation of homologous sex differentiation and steroid receptor genes among gonochores and hermaphrodites. The author identifies the optimal broodstock size and the appropriate candidate species for bait. He shows that the analysis of steriles and mutants has demonstrated the value of fishes as a system for genetic dissection of human development and diseases.

Plastics show up in every area of our lives. They are durable, cheap and light, properties that make them attractive but also problematic for the environment. The focus of this book is not just to highlight the problem of plastics, its definition, and how plastic pollution is impacting human health and environment but also to look at some best practices in both nature based solutions and in the field of law and policies. The first section of the book focuses on plastic pollution – it’s origin, relationship to climate change, linear/circular economy, followed by sustainable plastics, scientific solutions, and how policies can address plastic pollution. This includes looking at better designs, more sustainable feedstocks, and partnerships between various stakeholders worldwide including USA, China, Canada, South Korea, Thailand. This book will interest those who are associated with the production industry, packaging industry, and waste management industry as well as, academicians, students and policymakers.

Endocrine Sex Differentiation in Fish

  • Publisher: CRC Press

Of all vertebrates, fish exhibit unparalleled diversity of sexual plasticity and flexibility, ranging from gonochorism to unisexualism, and exceptional patterns of functional hermaphroditism. Fish farming and monosex aquaculture have led to reproductive dysfunction with males producing less milt, and females failing to ovulate and spawn. This book brings together relevant information on the role of the endocrine system on sexual differentiation in fish, and bridges the gap between molecular endocrinologists and fishery scientists.

Plant Virus and Viroid Diseases in the Tropics

Plant virus and sub-viral pathogens pose severe constraints to the production of wide range of economically important crops worldwide. The crops raised both through true seed and vegetative propagated materials are affected with number of virus and virus-like diseases. The virus may enter into plants through seed planting materials or by vectors. Once the virus is in the field, it multiplies and spreads following definite patterns depending upon the nature of the vector and agro-meteorological conditions. Disease free crops and plants are great economic and social importance in feeding the world's population. Detection of virus and sub-viral agents at initial stages of infection is critical to reduce economic losses. For nearly two decades, ELISA and its variants played a major role in large scale virus testing and also in the production of virus-free planting materials.

This book is the first to report that research in allogenics/xenogenics has conclusively shown that fishes have retained bisexual potency even after sexual maturity and spermiation. The XY genotype found in the unexpected female phenotypes sired by supermales (Y1Y2) and androgenic males (Y2Y2) points out the need to employ sex specific molecular ma

Dating back to the early Cambrian period, crustaceans had ample time to undertake endless experimentation with form and function. Today, no other group of plants or animals on the planet exhibit the range of morphological diversity seen among extant Crustacea. With more than 52,000 species, they are placed fourth in terms of overall species diversi
