This study confirmed the high genetic diversity among date palms in Sudan which was reported in previous studies. The use of morphological characterization, molecular analysis and interviewing of farmers, assisted in the successful fulfillment of the set of objectives to collect, document and analyze data pertaining to the present status of local date palm genetic resources in the Northern region of Sudan (River Nile and Northern States) with regard to cultivars, production and threats. The results of this study will contribute to the formulation of a national strategy for the conservation and sustainable use of the date palm genetic resources in Sudan. Further studies including chloroplast DNA to identify the origin of the seedling cultivars (Jaw and males) are warranted.
Date palm (Phoenix dactylifera L.) family (Arecaceae) is the most important and ancient cultivated species in Sudan. Assessments of genetic diversity in date palm cultivars facilitate effective selection and shorten the breeding time, two techniques (SDS-PAGE) based protein and Inter-simple sequence repeat (ISSR-PCR) were used to evaluate genetic diversity of five Sudanese date palm cultivars (Mishriq, Barhi, Khadrawi, Sagay and Khenaizy). The most remarkable result of the current study is that some genotypes revealed a unique profile with the primers and the results were reproducible and this can be used for DNA fingerprinting and cultivars identification. . Fifty nine polymorphic loci, UPGMA ordered the date palm cultivars into two main clusters, Cluster analysis on ISSR and SDS-PAGE data clearly discriminated the high degree of independence between the geographical origin and molecular data which were indicated. Generally, the genotypes which tested revealed that the geographic origin was not affected the cluster divisions.

This book is the first volume of a comprehensive assemblage of contemporary knowledge relevant to genomics and other omics in date palm. Volume 1 consists of 11 chapters arranged in 3 parts grouped according to subject. Part I, Biology and Phylogeny, focuses on date palm biology, evolution and origin. Part II, Biodiversity and Molecular Identification, covers conformity of in vitro derived plants, molecular markers, barcoding, pollinizer genetics and gender determination. Part III, Genome Mapping and Bioinformatics, addresses genome mapping of nuclear, chloroplast and mitochondrial DNA, in addition to a chapter on progress made in date palm bioinformatics. This volume represents the efforts of 30 international scientists from 10 countries and contains 78 figures and 30 tables to illustrate presented concepts. Volume 2 is published under the title: Omics and Molecular Breeding.
This book lists all validly published names of palms, providing the source of their publication and indication of which names are currently accepted and which are synonyms. Geographical distribution is also included for all accepted species.
This important reference book is the first comprehensive resource worldwide that reflects research achievements in date palm biotechnology, documenting research events during the last four decades, current status, and future outlook. This book is essential for researchers, policy makers, and commercial entrepreneurs concerned with date palm. The book is invaluable for date palm biotechnology students and specialists. This monument is written by an international team of experienced researchers from both academia and industry. It consists of five sections covering all aspects of date palm biotechnology including A) Micropropagation, B) Somaclonal Variation, Mutation and Selection, C) Germplasm Biodiversity and Conservation, D) Genetics and Genetic Improvement, and E) Metabolites and Industrial Biotechnology. The book brings together the principles and practices of contemporary date palm biotechnology. Each chapter contains background knowledge related to the topic, followed by a comprehensive literature review of research methodology and results including the authors own experience including illustrative tables and photographs.
The Date Palm is one of earliest crops planted in the ancient world. It is the main source of livelihood for Egyptian farmers and their families. Besides being a source of food and animal fodder and used in trading, it is also utilised in housing construction, furniture manufacturing, home accessories and other personal needs. Date Palms are considered a national wealth, given their economic, social and nutritional and health benefits. Therefore, they must be maintained, conserved and developed since their cultivation contributes to the national domestic income by more than three billion pounds a year. In an effort to promote Date Palm agriculture and develop a national strategic framework for its expansion in newly reclaimed land, this Atlas is an essential step in the identification and characterization of Date Palm cultivars in Egypt. ????? ???? ????? ??????? ?? ????? ???????? ???????? ?? ?????? ??????. ????? ???? ???? ????? ??????? ?????? ??????? ?? ???? ???? ????? ??????? ????? ?? ??? ??????? ??? ???? ?????? ??? ?????????? ??? ???? ?????? ?? ?????? ?????? ?????? ??????????? ???????? ??????????? ???????? ???????? ??? ???? ???????. ????? ????? ???? ????? ??????? ???? ????? ???????? ????????? ????? ???? ????? ?????? ????? ???????? ????????? ??? ??????? ?????? ???? ?? ???? ??????? ?? ???????? ??????. ?????? ?????? ?????? ?????? ???? ????? ??????? ?? ???? ???????????? ??????? ??? ?????? ?? ??????? ???????? ???? ??? ?????? ????? ?????? ?????? ?????? ????? ???? ????? ??????? ?? ???.
In developing countries, traditional fermentation serves many purposes. It can improve the taste of an otherwise bland food, enhance the digestibility of a food that is difficult to assimilate, preserve food from degradation by noxious organisms, and increase nutritional value through the synthesis of essential amino acids and vitamins. Although "fermented food" has a vaguely distasteful ring, bread, wine, cheese, and yogurt are all familiar fermented foods. Less familiar are gari, ogi, idli, ugba, and other relatively unstudied but important foods in some African and Asian countries. This book reports on current research to improve the safety and nutrition of these foods through an elucidation of the microorganisms and mechanisms involved in their production. Also included are recommendations for needed research.
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.
