Rice is a staple food for half of the worlds population mostly in Asia. Productivity of rice has largely been improved since the Green Revolution in 1960s. Further improvement of rice yield is necessary to keep pace with population growth, which is a challenging task for breeders. This book, Rice - Germplasm, Genetics and Improvement, as its name implies, comprehensively reviews current knowledge in germplasm exploration, genetic basis of complex traits, and molecular breeding strategies in rice. In the germplasm part, we highlight the application of wild rice in rice breeding. In the genetics part, most of the complex traits related with yield, disease, quality have been covered. In the improvement part, Chinese experiences in hybrid rice breeding have been summarized together with many molecular breeding practices scattering in different chapters.

Rice blast, caused by the fungal pathogen Magnaporthe grisea, is one of the most destructive rice diseases worldwide and destroys enough rice to feed more than 60 million people annually. Due to high variability of the fungal population in the field, frequent loss of resistance of newly-released rice cultivars is a major restraint in sustainable rice production. In the last few years, significant progress has been made in understanding the defense mechanism of rice and pathogenicity of the fungus. The rice blast system has become a model pathosystem for understanding the molecular basis of plant-fungal interactions due to the availability of both genomes of rice and M. grisea and a large collection of genetic resources. This book provides a complete review of the recent progress and achievements on genetic, genomic and disease control of the disease. Most of the chapters were presented at the 4th International Rice Blast Conference held on October 9-14, 2007 in Changsha, China. This book is a valuable reference not only for plant pathologists and breeders working on rice blast but also for those working on other pathysystems in crop plants.

Blast is an important foliar disease that infects the majority of cereal crops like rice, finger millet, pearl millet, foxtail millet and wheat, and thus resulting in a huge economic impact. The pathogen is responsible for causing epidemics in many crops and commonly shifts to new hosts. Magnaporthe spp. is the most prominent cause of blast disease on a broad host range of grasses including rice as well as other species of poaceae family. To date, 137 members of Poaceae hosting this fungus have been described in Fungal Databases. This book provides information on all blast diseases of different cereal crops. The pathogen evolves quickly due to its high variability, and thus can quickly adapt to new cultivars and cause an epidemic in a given crop. Some of the topics covered here include historical perspectives, pathogen evolution, host range shift, cross-infectivity, and pathogen isolation, use of chemicals fungicides, genetics and genomics, and management of blast disease in different cereal crops with adoption of suitable methodologies.In the past two decades there have been significant developments in genomics and proteomics approaches and there has been substantial and rapid progress in the cloning and mapping of R genes for blast resistance, as well as in comparative genomics analysis for resolving delineation of Magnaporthe species that infect both cereals and grass species. Blast disease resistance follows a typical gene-for-gene hypothesis. Identification of new Avr genes and effector molecules from Magnaporthe spp. can be useful to understand the molecular mechanisms involved in the fast evolution of different strains of this fungal genus. Advances in these areas may help to reduce the occurrence of blast disease by the identification of potential R genes for effective deployment. Additionally, this book highlights the importance of blast disease that infects different cereal hosts in the context of climate change, and genomics approaches that may potentially help in understanding and applying new concepts and technologies that can make real impact in sustainable management of blast disease in different cereal crops.

Major Fungal Diseases of Rice: Recent Advances provides a comprehensive overview of latest research in rice fungal pathology. There are 25 chapters dealing with the blast, sheath blight, sheath rot, brown spot and scald diseases of rice as well as some broader topics. The book covers recent progress in a number of key fundamental aspects such as pathogenicity, pathogen diversity, molecular characterisation, gene cloning, genetics of host resistance and host-pathogen interactions. It also presents the current status and perspectives in strategic and applied areas such as epidemiology, resistance breeding, biological control, induced resistance, seed-borne diseases and quarantine issues and disease management strategies. This book is essential for rice researchers, pathologists and breeders and will also be suitable for cereal and plant pathologists in general, as there is an extensive coverage of recent research advances in rice blast, a model system in plant pathology.

This book is open access under a CC BY 4.0 license. By 2050, human population is expected to reach 9.7 billion. The demand for increased food production needs to be met from ever reducing resources of land, water and other environmental constraints. Rice remains the staple food source for a majority of the global populations, but especially in Asia where ninety percent of rice is grown and consumed. Climate change continues to impose abiotic and biotic stresses that curtail rice quality and yields. Researchers have been challenged to provide innovative solutions to maintain, or even increase, rice production. Amongst them, the ‘green super rice’ breeding strategy has been successful for leading the development and release of multiple abiotic and biotic stress tolerant rice varieties. Recent advances in plant molecular biology and biotechnologies have led to the identification of stress responsive genes and signaling pathways, which open up new paradigms to augment rice productivity. Accordingly, transcription factors, protein kinases and enzymes for generating protective metabolites and proteins all contribute to an intricate network of events that guard and maintain cellular integrity. In addition, various quantitative trait loci associated with elevated stress tolerance have been cloned, resulting in the detection of novel genes for biotic and abiotic stress resistance. Mechanistic understanding of the genetic basis of traits, such as N and P use, is allowing rice researchers to engineer nutrient-efficient rice varieties, which would result in higher yields with lower inputs. Likewise, the research in micronutrients biosynthesis opens doors to genetic engineering of metabolic pathways to enhance micronutrients production. With third generation sequencing techniques on the horizon, exciting progress can be expected to vastly improve molecular markers for gene-trait associations forecast with increasing accuracy. This book emphasizes on the areas of rice science that attempt to overcome the foremost limitations in rice production. Our intention is to highlight research advances in the fields of physiology, molecular breeding and genetics, with a special focus on increasing productivity, improving biotic and abiotic stress tolerance and nutritional quality of rice.
