Soybean Cultivar Development: A Genome Perspective , Lisa Lou Lorenzen Jan 1994

Soybean Cultivar Development: A Genome Perspective , Lisa Lou Lorenzen

Retrospective Theses and Dissertations

The purpose of this dissertation was to retrospectively analyze the process of soybean cultivar development from a molecular perspective, by following the inheritance of RFLP markers in a pedigree analysis. Five methods of analysis are included in this dissertation;Sixty-four plant introductions, cultivars, and breeding lines were analyzed to define a core set of 97 probes with a high likelihood of detecting a polymorphism in elite germplasm. The ability to trace regions of chromosomes from parent to offspring and the application of pedigree-based mapping was demonstrated, which is the cosegregation of phenotypic traits and RFLP markers based on pedigree information ...

Telomeric Nucleic Acids: C-Strand Structure And A Telomerase Rna Mutant , Shawn Cameron Ahmed

Retrospective Theses and Dissertations

Telomeres, the ends of linear chromosomes, are composed of simple tandem repeats which are usually G·C rich. Telomeres are essential for chromosome stability, organizing the nuclear architecture and ensuring complete replication of the chromosomal terminus. To understand how telomeres carry out these fundamental cellular roles, one must understand the structural and dynamic properties of telomeric repeat sequences. Structural and genetic approaches were taken to learn more about telomeric nucleic acids;The structural portion of my research concerned an unusual DNA structure formed by the C-rich strand of telomeric DNA. Telomeric C-strand sequences form non-Watson-Crick structures in supercoiled plasmids at ...
