This book celebrates the dawn of the rye genomics era with concise, comprehensive, and accessible reviews on the current state of rye genomic research, written by experts in the field for students, researchers and growers. To most, rye is the key ingredient in a flavoursome bread or their favourite American whisky. To a farmer, rye is the remarkable grain that tolerates the harshest winters and the most unforgiving soils, befitting its legacy as the life-giving seed that fed the ancient civilisations of northern Eurasia. Since the mid-1900s, scientists have employed genetic approaches to better understand and utilize rye, but only since the technological advances of the mid-2010s has the possibility of addressing questions using rye genome assemblies become a reality. Alongside the secret of its unique survival abilities, rye genomics has accelerated research on a host of intriguing topics such as the complex history of rye’s domestication by humans, the nature of genes that switch fertility on and off, the function and origin of accessory chromosomes, and the evolution of selfish DNA.

This open access book covers a century of research on wheat genetics and evolution, starting with the discovery in 1918 of the accurate number of chromosomes in wheat. We re-evaluate classical studies that are pillars of the current knowledge considering recent genomic data in the wheat group comprising 31 species from the genera Amblyopyrum, Aegilops, Triticum, and other more distant relatives. For these species, we describe morphology, ecogeographical distribution, phylogeny as well as cytogenetic and genomic features. For crops, we also address evolution under human selection, namely pre-domestication cultivation and domestication. We re-examine the genetic and archeological evidence of where, when, and how domestication occurred. We discuss unique aspects of genome evolution and maintenance under polyploidization, in natural and synthetic allopolyploids of the wheat group. Finally, we propose some thoughts on the future prospects of wheat improvement. As such, it can be of great interest to wheat researchers and breeders as well as to plant scientists and students interested in plant genetics, evolution, domestication, and polyploidy.

Owing to its considerable winter hardiness, rye is a cereal that played a major role in the feeding of European populations throughout the Middle Ages. Recent data shows that rye is grown on about 5.4 million hectares, with a world production of approximately 13 million tons. While still an important bread food in many countries, rye produced for bread making has decreased or stagnated, whereas production is increasing for other market segments. Particularly, rye for feeding, ethanol processing, and biogas is promoted in Europe. The first comprehensive monograph on rye, Rye: Genetics, Breeding, and Cultivation gathers all the relevant and historic information from botany and genetics to utilization and sustainability of rye. The book covers taxonomy, morphology, and other botany-related aspects of rye. It describes its physiology, cytology, and genetics, including use for genetic improvement of other cereals. The author addresses various types of breeding such as population, hybrid, and molecular breeding. He also discusses rye cropping, including seeding techniques, fungal and viral diseases, and predators. The book examines the various uses for rye beyond bread making. This includes feeding, biomass and biogas production, ethanol production, and other important characteristics such as phytosterol content and antioxidant activity. It also explores the nutritional value of rye. Written by a leading expert in the field, this monograph compiles the most important facets of rye research, past and present.

This book presents an overview of the state-of-the-art in barley genome analysis, covering all aspects of sequencing the genome and translating this important information into new knowledge in basic and applied crop plant biology and new tools for research and crop improvement. Unlimited access to a high-quality reference sequence is removing one of the major constraints in basic and applied research. This book summarizes the advanced knowledge of the composition of the barley genome, its genes and the much larger non-coding part of the genome, and how this information facilitates studying the specific characteristics of barley. One of the oldest domesticated crops, barley is the small grain cereal species that is best adapted to the highest altitudes and latitudes, and it exhibits the greatest tolerance to most abiotic stresses. With comprehensive access to the genome sequence, barley’s importance as a genetic model in comparative studies on crop species like wheat, rye, oats and even rice is likely to increase.
