This book was released on 2009 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: New highly polymorphic simple sequence repeat (SSR) markers for European hazelnut (Corylus avellana L.). were developed from several sources. The markers were characterized, and segregation in a mapping population allowed to assign them to linkage groups. Their transferability across genera and species in the Betulaceae family was investigated. SSR markers were used to fingerprint several hazelnut accessions, including those from recent collections in northern Spain, Turkey, Georgia and Azerbaijan. A total of 170 new single-locus polymorphic SSR primers were developed in hazelnut: 76 from a library enriched for GA repeats, 13 from a library enriched for CA repeats, 23 from internal repeats in cloned inter simple sequence repeats (ISSR) fragments, 52 from repeats at the ends of ISSR fragments, and 6 from Betulaceae sequences in GenBank. These polymorphic loci were characterized using 50 hazelnut accessions, including the parents of a mapping population and 48 accessions that represented the high level of genetic diversity in European hazelnut. One hundred forty three of the new polymorphic SSR loci were mapped in a full-sib population. The map of the resistant parent consists of 344 markers (175 random amplified polymorphic DNA (RAPD) markers and 169 SSRs) spanning 837 cM with an average of 2.43 cM between markers, while the map of the susceptible parent consists of 366 markers (183 RAPDs and 183 SSRs) spanning 926 cM with an average of 2.53 cM between markers. SRR locus A601 co-segregated with the S-locus that controls pollen-stigma incompatibility, and four loci (B774, B720, B760, and SSR62) were tightly linked to the S-locus (_

This book was released on 2015 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: European hazelnut, an important nut crop in Oregon agriculture, is threatened by the fungal disease eastern filbert blight (EFB) caused by Anisogramma anomala (Peck) E. Müller. The hazelnut breeding program at OSU has been working on development of EFB-resistant cultivars. DNA markers allow mapping of traits using segregating progenies and identification of linked markers. The breeding of hazelnuts involves use of DNA markers to genotype individuals and facilitate selection in a procedure known as marker-assisted selection (MAS). This technique is particularly promising in tree crops with a long juvenile phase like the hazelnuts. 'Gasaway' resistance governed by a dominant allele at a single locus was identified and several EFB-resistant cultivars carrying the dominant allele from this source have been released. Infection of 'Gasaway' and some of its offspring by A. anomala isolates has been noted, and indicates an urgent need to investigate new sources of resistance, identify new resistance genes and incorporate them into the breeding effort. New microsatellite markers were developed from the genomic sequence of hazelnut cv. 'Jefferson'. A total of 17,802 simple sequence repeat (SSR) motifs exceeding 15 bp in length and consisting of tri-, tetra-, penta- and hexa- nucleotide repeats were identified in the 'Jefferson' genome. Removal of duplicates, short fragments, repeats at ends, and repeats containing only A's and T's reduced the number of unique fragments to 2,069. Visual inspection of these unique fragments alligned with genome sequences of 7 other accessions in Tablet software identified 489 sequences with variation in number of repeats but with conserved flanking regions. Amplification of a set of 24 diverse accessions and separation on agarose gels led to the development of 366 new polymorphic markers. These were used to genotype 48 diverse accessions using capillary electrophoresis for fragment sizing. An additional 15 parents were also fingerprinted at these new 366 microsatellite loci. Using the mapping population (OSU 252.146 x OSU 414.062), 213 loci were mapped. A dendrogram was constructed which showed a high level of polymorphism in hazelnut. Tightly linked markers were identified for 'Gasaway' resistance and MAS is routinely used. The hazelnut acreage in Oregon is increasing every year with the planting of these new EFB-resistant cultivars. However, concern about disease resistance breakdown prompted an investigation of 12 new EFB resistance sources. Segregating progenies were inoculated by placement of potted trees under an inoculation structure, in the greenhouse, or in the field by tying a diseased branch on each tree. A chi-square goodness-of-fit test was used compare observed with expected segregation ratios. Very few seedlings of Moscow selections N01, N01-06, and N01-07 were resistant and were likely escapes. 'Grand Traverse', C. heterophylla 'Ogyoo', 'Yoder #5', C. americana 'Rush', Moscow N23, N26, N27, and N37 segregated in 1:1 ratio, indicating resistance governed by a single locus and a dominant allele for resistance. 'Uebov' transmitted resistance to only ~15 % of its seedlings. Resistance from 'Uebov', 'Grand Traverse', and C. heterophylla 'Ogyoo' were assigned to LG6 but only 'Uebov' and 'Grand Traverse' were mapped. Resistance from 'Yoder #5', Moscow N27 and C. americana 'Rush' was assigned to LG7. Mapping of the remaining resistance sources will be completed in the future.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the production technology of temperate nuts. It explores cultivar and plant improvement, development and selection of rootstocks, plant–water relations and irrigation, canopy architecture, and postharvest packaging of nut fruits. It also deals with organic approaches, biotechnological interventions, diseases, and pest management. Contributing authors address nut fruits such as walnut, pecan nut, chestnut, and hazel nut on different recent aspects. The development achieved in the fruit sector is indicative of the fact that there is growing demand of fruit produce. Temperate nuts with health benefits and market acceptability have best sources of fat, fiber, protein, and mineral. They provide dietary fiber, potassium, and a variety of health-protective bioactive compounds. Apart from the health benefits, production of temperate nuts improves the economy of the country as these are very good source of income and employment. In addition, there is wide diversification in the production pattern of nuts globally. Increased production technology such as hybrids, high-yielding selections/ varieties, improved propagation techniques, and increased use of fertilizers and manures have brought spectacular increase in the production of nut fruits. This book is of interest to teachers, scientists, researchers, and scholars. Also, the book serves as additional reading material for undergraduate and postgraduate students of agriculture and horticulture. Horticulture nurseries and orchard industries also find this to be a useful read.

Download or read book Comparative and Evolutionary Genomics of Angiosperm Trees written by Andrew Groover and published by Springer. This book was released on 2017-11-21 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marking the change in focus of tree genomics from single species to comparative approaches, this book covers biological, genomic, and evolutionary aspects of angiosperm trees that provide information and perspectives to support researchers broadening the focus of their research. The diversity of angiosperm trees in morphology, anatomy, physiology and biochemistry has been described and cataloged by various scientific disciplines, but the molecular, genetic, and evolutionary mechanisms underlying this diversity have only recently been explored. Excitingly, advances in genomic and sequencing technologies are ushering a new era of research broadly termed comparative genomics, which simultaneously exploits and describes the evolutionary origins and genetic regulation of traits of interest. Within tree genomics, this research is already underway, as the number of complete genome sequences available for angiosperm trees is increasing at an impressive pace and the number of species for which RNAseq data are available is rapidly expanding. Because they are extensively covered by other literature and are rapidly changing, technical and computational approaches—such as the latest sequencing technologies—are not a main focus of this book. Instead, this comprehensive volume provides a valuable, broader view of tree genomics whose relevance will outlive the particulars of current-day technical approaches. The first section of the book discusses background on the evolution and diversification of angiosperm trees, as well as offers description of the salient features and diversity of the unique physiology and wood anatomy of angiosperm trees. The second section explores the two most advanced model angiosperm tree species (poplars and eucalypts) as well as species that are soon to emerge as new models. The third section describes the structural features and evolutionary histories of angiosperm tree genomes, followed by a fourth section focusing on the genomics of traits of biological, ecological, and economic interest. In summary, this book is a timely and well-referenced foundational resource for the forest tree community looking to embrace comparative approaches for the study of angiosperm trees.

Download or read book The Handbook of Plant Genome Mapping written by Khalid Meksem and published by John Wiley & Sons. This book was released on 2006-03-06 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the complete sequencing of the genomes of model organisms such as a multitude of bacteria and archaea, the yeast Saccharomyces cerevisiae, the worm Caenorhabditis elegans, the fly Drosophila melanogaster, and the mouse and human genomes have received much public attention, the deciphering of plant genomeswas greatly lagging behind. Up to now, only two plant genomes, one of the model plant Arabidopsis thaliana and one of the crop species rice (Oryza sativa) have been sequenced, though a series of other crop genome sequencing projects are underway. Notwithstanding this public bias towards genomics of animals and humans, it is nevertheless of great importance for basic and applied sciences and industries in such diverse fields as agriculture, breeding in particular, evolutionary genetics, biotechnology, and food science to know the composition of crop plant genomes in detail. It is equally crucial for a deeper understanding of the molecular basis of biodiversity and synteny. The Handbook of Genome Mapping: Genetic and Physical Mapping is the first book on the market to cover these hot topics in considerable detail, and is set apart by its combination of genetic and physical mapping. Throughout, each chapter begins with an easy-to-read introduction, also making the book the first reference designed for non-specialists and newcomers, too. In addition to being an outstanding bench work reference, the book is an excellent textbook for learning and teaching genomics, in particular for courses on genome mapping. It also serves as an up-to-date guide for seasoned researchers involved in the genetic and physical mapping of genomes, especially plant genomes.
