The stone fruits—including peaches, apricots, almonds, plums, and cherries—have been bred and grown for thousands of years and today are significant agricultural crops in many local economies worldwide. This volume presents a comprehensive commentary on classical genetics and breeding, molecular mapping and breeding of agronomic traits, and the cloning of genes of interest. It also explores recent advances on omics sciences including structural and functional genomics, proteomics, nd metabolomics. The book enumerates the whole genome sequencing of the model fruit plant peach and discusses bioinformatic strategies and tools for stone fruit research

This book collates the most up to date information on Fragaria, and Rubus genomes. It focuses on the latest advances in the model system Fragaria vesca, along with the allied advances in economically important crops. Covering both basic and applied aspects of crop genomics, it illustrates strategies and resources for the study and utilization of genome sequences and aligned functional genomics resources. Rosaceous berries are collectively an increasingly important set of high-value global crops, with a trade value of over £2 billion dollars per annum. The rosaceous berries strawberry, raspberry and blackberry share some common features at the genome scale, namely a range of ploidy levels in each genus and high levels of heterozygosity (and associated inbreeding depression) due to self-incompatibility systems, dioecy, or multispecies hybridization events. Taken together, although the genomes are relatively compact, these biological features lead to significant challenges in the assembly and analysis of berry genomes, which until very recently have hampered the progress of genome-level studies. The genome of the woodland strawberry, Fragaria vesca, a self-compatible species with a homozygous genome was first sequenced in 2011 and has served as a foundation for most genomics work in Fragaria and to some extent Rubus. Since that time, building upon this resource, there have been significant advances in the development of genome sequences for related crop species. This, coupled with the revolution in affordable sequencing technology, has led to a suite of genomics studies on Fragaria and more recently Rubus, which undoubtedly aid crop breeding and production in future years.

This book reviews the current status of P. mume research, highlighting how the new data coming from the release of the P. mume genomes can advance science and help to solve a number of problems facing the P. mume industry. Prunus mume, which was domesticated in China more than 3,000 years ago as an ornamental plant and for its fruit, is one of the first genomes among the Prunus subfamilies of the Rosaceae family that has been sequenced. Combining the P. mume genome with available data, scientists have succeeded in reconstructing nine ancestral chromosomes of the Rosaceae family, as well as the chromosome fusion, fission and duplication history of three major subfamilies. The P. mume genome sequence adds to our understanding of Rosaceae evolution and provides an important basis for the improvement of fruit trees. This book offers an essential a guide for all those who are interested in gene discovery, comparative genomics, molecular breeding and new breeding techniques; and will be particularly useful for scientists, breeders, university students, and public sector institutes that are involved in the P. mume industry and/or Rosaceae research.

Recent interest in the health-related, culinary, and biological properties of berries is stimulating new initiatives in berry breeding and production. Breakthroughs in molecular technologies allow genomics-enabled approaches to augment research efforts. This volume documents the basic botany and culture of four major berry crops and follows the scientific milestones that have ushered these systems into the modern genomics era. Leading researchers in each crop system detail the recent findings in genetics, genomics, and breeding that seek to improve sustainable cultivation, fruit quality, and availability.

Addressing the pear genome, this book covers the current state of knowledge regarding genetic and genomic resources, breeding approaches and strategies, as well as cutting-edge content on how these tools and resources are being / soon will be utilized to pursue genetic improvement efforts that will combine fruit quality, high productivity, precocious fruit bearing, and long postharvest storage life, along with elevated levels of resistance to various major diseases and insect pests. Throughout, the book also explores potential opportunities and challenges in genomic analysis, sequence assembly, structural features, as well as functional studies that will assist in future genetic improvement efforts for pears. The pear (Pyrus), an important tree fruit crop, is grown worldwide, and has several economically relevant cultivars. In recent years, modern genetic and genomic tools have resulted in the development of a wide variety of valuable resources for the pear. In the past few years, completion of whole genome assemblies of ‘Dangshansuli’, an Asian pear, and ‘Bartlett’, a European pear, have paved the way for new discoveries regarding for example, the pear’s genomic structure, chromosome evolution, and patterns of genetic variation. This wealth of new resources will have a major impact on our knowledge of the pear genome; in turn, these resources and knowledge will have significant impacts on future genetic improvement efforts.
