Abstract:

Thesis (MSc)--Stellenbosch University, 2012.<br>Triticale is an amphidiploid that consists of wheat (A and B) and rye (R) genomes. This cereal is fast becoming important on a commercial basis and warrants further assessment for the better management and breeding of the hybrid. The assessment of the genetic diversity among the wheat and rye genomes within triticale can be obtained by using molecular markers developed in both donor genomes. Simple sequence repeats markers (SSRs) and amplified fragment length markers (AFLPs) have been previously used to assess the genetic diversity among tritical

This thesis focuses on empirical investigations and refinements of immunohistochemical marker chemistry to gain insights into the design of novel markers for light and electron microscopy. In Chapter 2, incorporation of d-block metals into polymerised biphenyl-3,3′,4,4′-tetramine (polyDAB) identified complexes of Ni(II), Pt(II), Pt(IV) and Au(III) to be powerful catalysts of silver reduction from physical developers. Na2S(aq) treatment increased the range and activity of catalytic complexes, allowing previously invisible immunohistochemical deposits of polyDAB to be clearly seen in diagnostica

Abstract:

Barley (Hordeum vulgare L.) is one of the most important cereal crops in North Dakota, which ranks second amongst all states for barley production in the United States. Barley is used for the production of malt, which is used for brewing beer. The malting and brewing industries set strict standards for malt quality; yet, determining malt quality of experimental barley lines is very expensive. For this reason, quality is typically determined at the latter stages of the breeding program, resulting in rejection of many genotypes after large investments for agronomic performance, disease resistanc

S1 gene product, pS1, a statin-like protein fused with $ beta$-galactosidase, was cleaved by an endogenous protease from E. coli; therefore, we reconstructed S1 into a pPL-$ lambda$ vector with a thermo-inducible promoter.

Penstemon Mitchell (Plantaginaceae) is one of the largest, most diverse plant genera in North America. Their unique diversity, paired with their drought-tolerance and overall hardiness, give Penstemon a vast amount of potential in the landscaping industry—especially in the more arid western United States where they naturally thrive. In order to develop Penstemon lines for more widespread commercial and private landscaping use, we must improve our understanding of the vast genetic diversity of the genus on a molecular level.

Genetic analysis of seedling stripe rust resistance in a wheat landrace AUS27858 indicated the involvement of two genes. These genes were temporarily named YrAW1 and YrAW2.

DArT-based bulked segregant analysis located YrAW1 on chromosome 4AL and YrAW2 on 3BS. YrAW1 was formally named Yr51. Markers owm45F3R3 and sun104 flanked Yr51 at genetic distances of 1.2 cM and 2.5 cM on the proximal and distal sides, respectively. Marker sun104 was validated on a set of 40 genetica

Abstract:

Co-dominant molecular markers, such as Microsatellites (or Simple Sequence Repeats, SSRs), are powerful tools for basic and applied research programs in crop plant species. Among the possible applications, they are frequently adopted for genetic traceability of food products, for assessing the genetic diversity of local varieties as well as the genetic identity of modern varieties, and also for marker-assisted breeding purposes. In fact, SSR markers are known to be highly polymorphic and discriminant, well distributed throughout the genome, not affected by environmental factors, more efficient

Abstract:

The phylogeny of land plants, especially angiosperms, has been perplexing scientists for more than 125 years. The aim of this study was to help elucidate unanswered phylogenetic issues using rpb1 genes from twenty-six land plant species (8 gymnosperm species, 17 angiosperm species and Psilotum, a fernally, as the outgroup). The sixteen rpb1 genes which were sequenced in this study had very similar lengths and contained no base compositional bias. Synonymous substitutions of rpb1 sequences were saturated when compared to the outgroup. The third codon positions of these genes contained mislea

Abstract:

Fusarium head blight (FHB) is one of the most destructive diseases of common wheat (Triticum eastivum L.) worldwide. Resistance to FHB is an ideal trait for which molecular marker assisted selection (MAS) would facilitate breeding and cultivar development efforts. Validation of quantitative trait loci (QTL) conferring FHB resistance is a prerequisite for MAS. This study was conducted to validate and evaluate the effect of two major QTL, previously reported on chromosomes 3BS and 5AS, on multiple FHB resistance components in two independent studies, one involving a mapping population derived fr

Abstract:

<p>Epithelial cell polarisation is a prerequisite for the branching morphogenesis in several organs. Differential screening techniques were used to identify genes, which are upregulated during induction of epithelium in early kidney development. This investigation revealed two separate genes, Nuclear localising protein 1 (Nulp1), a previously undescribed gene with sequence characteristics of the basic helix-loop-helix transcription factor family, and glycoprotein 210 (gp210, POM210), an integral membrane protein constituent of the nuclear pore complex (NPC). Of these, gp210 was found to be upr

Abstract:

The purpose of this research was to determine whether expression analysis of the IGF2 gene in zebrafish, a gene whose transcription is known to be regulated by DNA methylation in mammals, can be used as a marker or indicator of DNA methylation due to toxin exposure in fish embryos. We examined the expression of IGF2, IGF1, and IGFBP-1 in zebrafish embryos treated with sodium arsenite (thought to inhibit DNA methylation), nickel chloride (thought to cause DNA hypermethylation), trichostatin A (a histone deacetylase inhibitor), 5-azaC (thought to cause methyltransferase inhibition), cadmium chl

Abstract:

Poa L., is known as a highly diverse cosmopolitan genus with taxonomic difficulties that includes unknown species and species with uncertain affinities mainly in West Asia and North Africa. Poa also exhibits a close relationship with two West Asian genera, Eremopoa Roshev. and Oreopoa H. Scholz & Parolly. This study was conducted to: 1) fill the gap of information on the affinities between Poa species with an emphasis on West Asian Poa; 2) revise and evaluate the accuracy of traditional infrageneric classification of West Asian Poa; and 3) clarify the relationship between Poa and two allied ge

Abstract:

In common bean (Phaseolus vulgaris), the main seed storage pests are the bruchid beetles. Damage done to the seed by the larvae has a large impact on seed quality and yield. Arcelin (ARC), phytohaemagglutinin (PHA), and α-amylase inhibitor (α-AI) are linked seed storage proteins that form the APA locus on chromosome Pv04 and are associated with resistance. A major breeding objective is to introduce bruchid resistance into common bean from a resistant tepary genotype, G40199, by introgressing the resistant APA locus into susceptible common bean backgrounds. Here we developed a molecular marke
