Book Description
Almond (Prunus dulcis), a stone fruit belonging to a family Rosaceae (rose) is broadly cultivated for ornament and fruit. Within this genus, the almond is very much associated with the peach, and these two fruits share the same subgenus the Amygdalus. About 430 species are spread all through the northern temperate regions of the world. The Mediterranean climate region of the Middle East like Turkey and Pakistan eastward to Syria is native to the almond and its related species. Almond is one of the ancient fruit trees known to the Asian as well as European regions with the most primitive proof of cultivation dating about 2000 B.C. Prunus dulcis (Almond) is a nutrient-loaded nut crop. Almond possesses a great genetic diversity due to the genetically controlled self-incompatibility system which can be estimated by a morphological characteristic including molecular markers and isoenzymes with a wide range of marker techniques. Simple sequence repeats (SSR) involving RFLP or SNP are the most commonly used molecular techniques among the DNA-based molecular symbols. Particular agronomic characters, e.g. kernel bitterness or self-compatibility can also be traced by these molecular markers. The direct association between the level of diversity and the basis of the germplasm cannot be understood by the studies of genetic diversity. Genetic diversity cannot be seriously lost by self-compatibility in almonds. The breeding, conservation, and cultivation of wild-growing almonds may similarly advantageous after the genetic diversity research studies (especially those applying molecular markers).

Book Description
Zusammenfassung: Almond and peach species have global importance as food crops as well as use in landscaping including restoration and reforestation. Because currently available breeding germplasm has a very narrow genetic base, genetic improvement programs are turning to wild germplasm as sources of improved quality, productivity and resistance traits. This germplasm is also enabling the dramatic modification of traditional cropping systems as with the transfer of self-fruitfulness from related wild almond and peach species to normally self-sterile cultivated almond. While presence of an extensive wild almond and related germplasm has been documented in the literature over the past century, most information remains dispersed and often not generally accessible owing to its publication in treatises and journals of limited distribution. This monograph brings together a comprehensive characterization of almond and its related species including the cultivated and wild peaches. Because it represents the only comprehensive source of information on almond, peach and their wild relatives, it represents a basic reference text of interest to researchers in both the basic and applied plant and ecological sciences

Book Description
This book brings together the latest information on almond genomics and transcriptomics, with a particular focus on cutting-edge findings, tools, and strategies employed in genome sequencing and analysis with regard to the most important agronomic traits. Cultivated almond [(Prunus dulcis (Miller) D. A. Webb, syn. Prunus amygdalus Batsch., Amygdalus communis L., Amygdalus dulcis Mill.)] is a tree crop producing seeds of great economic interest, and adapted to hot and dry climates. Domesticated in Southeast Asia, its small diploid genome and phenotypic diversity make it an ideal model to complement genomics studies on peach, generally considered to be the reference Prunus species. Both represent consanguineous species that evolved in two distinct environments: warmer and more humid in the case of peach, and colder and xerophytic for almond. The advent of affordable whole-genome sequencing, in combination with existing Prunus functional genomics data, has now made it possible to leverage the novel diversity found in almond, providing an unmatched resource for the genetic improvement of this species.

Book Description
'Jeffries' is almost identical to 'Nonpareil' in tree and nut characteristics, except for unusually high productivity in certain crossing situations. Field data supports a unilateral incompatibility between 'Jeffries' and cultivars carrying the S haplotype and, consequently, suggests that the 'Jeffries' mutant expresses only one effective S-allele (S) of the putative 'Nonpareil' parent genotype (S--S8). Simple sequence repeats (SSRs) were used to assess parent-progeny relationships to clarify the true identity of 'Jeffries'. Two of nine SSR alleles tested are distinct between 'Jeffries' and 'Nonpareil', making a seedling origin for 'Jeffries' plausible. Moreover, physiological changes reportedly controlled by independently inherited, multiple genes and a significant shift for quantitative traits located on multiple, independent linkage groups provide compelling evidences that 'Jeffries' is not the result of a single mutation of 'Nonpareil'. Genotyping the 'Jeffries' S-alleles showed a band that appeared to be S-- on the gel. Its corresponding sequences strongly matched the published S-- sequences available in NCBI database. The same was true for the S8 allele. NCBI returned a hit that is 93% similar to a previously published S8-haplotype sequence. Results suggest that the genotype of 'Jeffries' is S--S8 with S---RNase present in a very low efficacy. Seed-set data taken from a large sampling of almond cultivars, including multiple cross-incompatibility groups, show a wide variability for seed sets that do not strictly follow the groupings previously established for cross-incompatibility groups. Results indicate that considerable variability in seed-sets is common in established self- and cross-incompatibility groups as well as self- and cross-compatibility groups, indicating that other genes in addition to the major S-gene are involved.

Book Description
The Molecular Basis of Plant Genetic Diversity presents chapters revealing the magnitude of genetic variations existing in plant populations. Natural populations contain a considerable genetic variability which provides a genomic flexibility that can be used as a raw material for adaptation to changing environmental conditions. The analysis of genetic diversity provides information about allelic variation at a given locus. The increasing availability of PCR-based molecular markers allows the detailed analyses and evaluation of genetic diversity in plants and also, the detection of genes influencing economically important traits. The purpose of the book is to provide a glimpse into the dynamic process of genetic variation by presenting the thoughts of scientists who are engaged in the generation of new ideas and techniques employed for the assessment of genetic diversity, often from very different perspectives. The book should prove useful to students, researchers, and experts in the area of conservation biology, genetic diversity, and molecular biology.

Book Description
Trees that are indispensably supportive to human life pose a formidable challenge to breed them to suit to human needs. From soft drinks to breweries to beverages to oil to tires, the value added products from trees give a spectrum of products to human kind. While attempts to tap these resources through conventional breeding are underway, the quick and elegant way of manipulating the genetic systems at the genome level is an essential chapter of modern science. Books featuring genomics of tree crops are few, and genomics is such a science that changes rapidly. Genomics of Tree Crops is an earnest attempt towards compiling genomics of tree crops. Plant genomics has made monumental strides in the last decade providing insights into intra-genomic phenomena such as heterosis, epistasis, pleiotropy and other interactions between loci and alleles within the genome. In contrast, the investigation of the roles and functions of single genes is a primary focus of molecular biology and is a common topic of modern genetic research. A genome is the sum total of all of an individual organism's genes. Thus, genomics is the study of all the genes of a cell, or tissue, at the DNA (genotype), mRNA (transcriptome), or protein (proteome) levels. The complete sequencing of the three billion base pair human genome with 25,000 genes identified and the invention of DNA microarrays ushered in a new era in the science of genomics leading to explosive advancements in oncology diagnostics. This impetus into the genomics era lead the way toward advances in plant genomics which started with Arabidopsis thaliana and went through an array of crops such as rice, maize, papaya, various cereals and legumes, with pigeon pea added to the list towards the end of 2011. Trees, on the other hand, are the least attended taxa with regard to genomic research. Some of the areas that attained attention of the scientists are: DNA sequencing, bioinformatics, genomics of flowering, gene flow, spatial structure, local adaptation and assisted migration in trees, transformation of fruit trees, genomics of tropical and temperate fruit trees, genomics of Hevea rubber, genomics of papaya and genomics of palms. Genomics of Tree Crops compiles this information with chapters authored by experts on these crops.
