Abstract Details

2011, Master of Sciences, Case Western Reserve University, Biology.
The intergenic spacer (IGS) of the large rDNA gene array has been characterized in organisms across the domain Eukarya. A common characteristic of this region is length heterogeneity, not only between conspecific individuals, but within individual organisms. In most species, this heterogeneity has been found to result from one or more clusters of subrepeats, each containing a varying number of subrepeat units. Length heterogeneity has previously been observed in the IGS of the undomesticated legume Tylosema esculentum (commonly called marama). This locus was sequenced and the region containing subrepeat clusters compared amongst 21 individuals. The subrepeat clusters contributing to IGS length heterogeneity are identified, and the organization of these clusters within the marama IGS is compared to that of other species. The findings presented here suggest that the subrepeat region in marama is smaller and more complex than in the analogous regions of other species.
