Download or read book Minimum Tile derived Microsatellite Markers Improve the Physical Map of the Soybean Genome and the Flyer and Hartwig Genetic Map at Rhg Rfs and Yield Loci written by Samreen H. Kazi and published by . This book was released on 2005 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: The soybean ( Glycine max (L.) genome map encompasses 1,115 Mbp, 2,512 cM, and twenty chromosomes (SoyGD http://soybeangenome.siu.edu). Gaps in the genetic map hamper physical map completion. The aims were to efficiently construct a new genetic map, to fill gaps in the physical map and to identify novel quantitative trait loci (QTL). Used were microsatellite markers (142, 38 from physical map minimum tile path clone end-sequences), bulked-segregant analysis and the recombinant inbred line population Flyer x Hartwig (FxH; n=92). Three regions were positively associated with seed yield, one novel. Discovered were one new QTL for resistance to Sudden Death Syndrome associated leaf scorch measured by disease index and two QTL for the severity of root infection by the causal organism, Fusarium virguliforme . Four loci for resistance to soybean cyst nematode were identified and confirmed in near isogeneic lines. The new 2,494 cM map has improved the soybean genome map at SoyGD.

This book was released on 2007 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genome size of soybean is 1,115 Mbp with 20 consensus linkage groups that represent 20 chromosome pairs, 65% genetically active regions and about 40% heterochromatic DNA. It is complex with about 55% of highly repeated sequences and 25% of the genome is moderately repeated. The Soybean Genome Database (SoyGD) is a useful tool to get information on the integrated genetic and physical maps of Glycine max . There have been recent improvements by the addition of microsatellite markers that are anchored to the BACs. SSR markers tend to cluster on the genetic map of soybean. Single population maps that were dense enough showed gaps that encompassed almost a third of the soybean genome. The old map remained biased toward ATT motifs that may facilitate more gaps. Here 205 BAC-End Sequence derived SSR markers were used to screen ExF RILs for detecting polymorphism. Aim was to integrate the genetic and physical maps of soybean using markers that are not biased by only ATT. AT. CTT. CT types of repeats. Forty two were found to be polymorphic and thirteen markers were associated with twenty one of 59 traits by ANOVA. Three marker-trait associations were later inferred to be new QTL. The new ExF genetic linkage map was compared with soybean composite map, Kassem's map and soybean physical map. With the addition of these markers, the map was expanded by [approximately]200 cM with 19 linked markers on 12 linkage groups. This comparison proved helpful in correlating the BACs with the genetic map. Three previously detected QTL were confirmed by this study.

Download or read book The Soybean Genome written by Henry T. Nguyen and published by Springer. This book was released on 2017-09-20 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the application of soybean genome sequences to comparative, structural, and functional genomics. Since the availability of the soybean genome sequence has revolutionized molecular research on this important crop species, the book also describes how the genome sequence has shaped research on transposon biology and applications for gene identification, tilling and positional gene cloning. Further, the book shows how the genome sequence influences research in the areas of genetic mapping, marker development, and genome-wide association mapping for identifying important trait genes and soybean breeding. In closing, the economic and botanical aspects of the soybean are also addressed.

Download or read book Plant Cytogenetics written by Hank Bass and published by Springer Science & Business Media. This book was released on 2011-12-02 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference book provides information on plant cytogenetics for students, instructors, and researchers. Topics covered by international experts include classical cytogenetics of plant genomes; plant chromosome structure; functional, molecular cytology; and genome dynamics. In addition, chapters are included on several methods in plant cytogenetics, informatics, and even laboratory exercises for aspiring or practiced instructors. The book provides a unique combination of historical and modern subject matter, revealing the central role of plant cytogenetics in plant genetics and genomics as currently practiced. This breadth of coverage, together with the inclusion of methods and instruction, is intended to convey a deep and useful appreciation for plant cytogenetics. We hope it will inform and inspire students, researchers, and teachers to continue to employ plant cytogenetics to address fundamental questions about the cytology of plant chromosomes and genomes for years to come.
