Book excerpt: Rice (oryza sativa L.) is the most important staple food crop for more than 60% of the global population and forms the cheapest source of food and energy. Rice occupies 44.80 million ha area with 99.180 million tones production which is 42.4% of total food grains and productivity of 2214 kg/ha, In Andhra Pradesh it is grown in an area of 43.75 lakh ha is under rice cultivation with a production of 14.210 lakh tones and productivity of 3248 kg/ha. Rice yields are low in Telangana region during rabi season. In Telangana region the low temperature vary from 8oC to 16o C starting from December to first fortnight of February. optimum day temperature before heading is 31o-32o C and optimum night temperature is 21o-22o C and in the period for 15 days after heading vary from 8o to 16oC. Even after about three decades of the release of variety Tella hamsa. It is ruling variety for its cold tolerance during seedling stage and no other varieties developed are able to replace it. To develop cold tolerant rice varieties and to increase the present levels of heterosis for yield and utilize genetically divergent parents for inter and intra sub-specific crosses in rice.

Available in PDF, EPUB and Kindle. Book excerpt: Rice is the staple food for more than half of the world's population, yet cold temperatures during the cropping period cause a significant loss of yield. To cope with the world's increasing population, it is necessary to develop high yielding rice varieties that are tolerant to abiotic stress conditions, such as drought, salinity, and cold. This book provides a clear understanding of cold stress in rice in the hopes that it will provide insight to the subject for further research so that rice plants may be grown efficiently in cold regions with high productivity.

Available in PDF, EPUB and Kindle. Book excerpt: Nosema apis causes one the most important diseases of honey bees but is mostly overlooked by beekeepers as there are no characteristic obvious symptoms of disease it is known as 'the silent killer'. The repercussions of infection with this parasite are equivalent to the losses caused by all of the other diseases, including the more easily diagnosed brood diseases. This study consists of a literature review outlining the different facets of N. apis infections, including a section on the methodology for counting N. apis spores in adult honey bees, and a survey of honey bee colonies to determine the prevalence and severity of N. apis under Australian conditions.

Book excerpt: 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.

With the new technologies such as high-throughput genome sequencing and integrated "-omis" methods applied in rice researches, great advancements have been made. This book was aimed to show a glance of new advancements in the international rice researches. The first section of the book introduced rice cultivation and production. As core sections of the book, the second and third sections introduced physiological and genetic mechanisms on grain quality and biotic and abiotic stress resistance as well as breeding. In the last section, we introduced new technologies such as chromatin immunoprecipitation, integrated "-omis" methods, and bistatic interferometry technology in rice research.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers comprehensive coverage of important grain cereals including their origin and distribution, crop gene pool, level of diversity, production constraints, traits of importance for genetic base widening, crop improvement methodologies, genome mapping, genomics for breeding, and future strategies. The chapters, contributed by eminent crop researchers from around the world, provide rare insights into the crop-specific constraints and prospects drawing from their substantial experience. As such, the book offers an essential source of information for grain cereals scientists, teachers, students, policy planners and developmental experts alike. Grain cereals, which comprise rice, wheat, maize, barley, oats, sorghum and millets, are members of the grass family. These crops are vital to human nutrition, thanks to their roles as staple food crops in different parts of the globe. Some of them are rich sources of carbohydrates, which provide energy, while others are important sources of minerals, vitamins and proteins, in addition to their medicinal properties. In most cereals, the existing variability among elite germplasm has been exploited to attain a desirable level of productivity. However, to make further breakthroughs in enhancing yield and improving stability in future crop cultivars, new sources of genes/alleles need to be identified in wild/weedy species and incorporated into the cultivated varieties. Though there have been many publications on various aspects of grain cereal improvement in the recent past, to date this essential information has remained scattered among different periodicals.
