TL;DR: This paper provided a glimpse of the advances in genetic resources and genomics research of peanut made during the last decade and provided an overview of the latest information on genetic and genomic resources, genetic and trait mapping, proteomic and transcriptomic analyses, functional and comparative genomics studies.
Abstract: Peanut, an amphidiploid, is an important food and oil crop and has an interesting evolutionary history. This book provides a glimpse of the advances in genetic resources and genomics research of peanut made during the last decade. It contains an overview of germplasm, advances in genetic and genomic resources, genetic and trait mapping, proteomic and transcriptomic analyses, functional and comparative genomics studies, and molecular breeding applications. This book should prove useful to students, teachers, and young researchers as a ready reference to the latest information on peanut genetics and genomics.

TL;DR: New theories and technologies recently developed in relation to plant breeding are reviewed, enabling genotyping by sequencing and sequence-based marker technology and molecular breeding strategies to become a viable option, one widely used in large multinational seed companies.
Abstract: Molecular breeding, including both marker-assisted breeding and genetic engineering, has experienced significant innovations and advances during the past three decades. Starting with Mendelian genetics, plant breeders have progressed from using morphological markers to protein isozymes and then ultimately to DNA-based markers, which have enabled routine genome-wide analysis. As a result, thousands of genes and quantitative trait loci (QTL) have been mapped across the major crop species, laying the foundation for marker-assisted selection (MAS) techniques, such as precise marker-assisted backcrossing, to transfer desirable loci into breeding lines. With the subsequent development of advanced MAS strategies, including QTL pyramiding, marker-assisted recurrent selection and genomic selection, marker-assisted approaches have led to rapid gains in selection for plant breeding programs. Breeding by design and genetic modeling have received great attention as designing a desirable plant based on marker and associated gene information becomes increasingly possible. Following rice as the first crop species sequenced, whole genome sequences have been increasingly available for more and more crop species, enabling genotyping by sequencing and sequence-based marker technology and molecular breeding strategies to become a viable option, one widely used in large multinational seed companies. With significant reduction of genotyping cost and increased throughput, next-generation sequencing and SNP genotyping technologies are increasingly making MAS a choice of public-sector plant breeding as well. Now crop genomic diversity can be characterized at the sequence level based on haplotype maps, and molecular breeding can be further accelerated through allele mining and haplotype-based design and selection. With all the developments and significant advances in various fields of molecular biology and their integration with platforms and tools, molecular breeding is rapidly moving into the vanguard of mainstream breeding programs. To review and evaluate new theories and technologies recently developed in relation to plant breeding, the 3rd International Conference on Plant Molecular Breeding (ICPMB) was held in Beijing, China, Sept. 5–9, 2010. The conference was organized by an International Organization Committee represented by Zhi-Kang Li (Chinese Academy of Agricultural Sciences/International Rice Research Institute), Jean-Marcel Ribaut (the Generation Challenge Program), Aimin Zhang (Chinese Y. Xu (&) Institute of Crop Sciences/International Maize and Wheat Improvement Center (CIMMYT), Chinese Academy of Agricultural Sciences, 100081 Beijing, China e-mail: y.xu@CGIAR.ORG

TL;DR: The potential application of DNA markers in the breeding of crop plants and the benefits and limitations of the use of marker-assisted technologies in comparison with conventional plant breeding methods are considered.
Abstract: Over the past decades, wide theoretical and practical experience has been obtained in the application of DNA markers for the investigation of plant genetic diversity, the construction of molecular genetic maps, the mapping of genes and quantitative trait loci, and the employment of molecular marker technologies in the development of commercial cultivars and breeding of crop lines. To date, the main practical application of molecular markers is related to germplasm characterization, introgression and the pyramiding of genome fragments associated with agronomically important traits controlled by major genes. The contribution of new technologies to the selection of traits with multigenic inheritance is still insignificant. Despite considerable progress in plant molecular genetics and genomics methods and great interest in new technologies among breeders, there are a large number of constraints affecting the implementation of new technologies in breeding practice. This article considers the potential application of DNA markers in the breeding of crop plants and the benefits and limitations of the use of marker-assisted technologies in comparison with conventional plant breeding methods.
