Physical Mapping Of Ribosomal Genes In New World Members Of The Genus Chenopodium Using Fluorescence In Situ Hybridization, Maria C. Sederberg Oct 2008

Physical Mapping Of Ribosomal Genes In New World Members Of The Genus Chenopodium Using Fluorescence In Situ Hybridization, Maria C. Sederberg

Theses and Dissertations

The genus Chenopodium contains many economically important species in the New World, but is relatively understudied and poorly understood, especially in terms of evolutionary relationships. A better understanding of the structure of this genus could significantly help in breeding efforts on its cultivated members, notably the tetraploid C. quinoa and also certain varieties of C. berlandieri, also tetraploid. Of special concern is determining which diploid weed species are the most likely ancestors for C. quinoa, C. berlandieri, and the other tetraploid members of subsection Cellulata. The phylogeny can be understood in part by examining the ribosomal RNA loci and observing …


Evaluation Of Downy Mildew (Peronospora Farinosa F.Sp. Chenopodii) Resistance Among Quinoa Genotypes And Investigation Of P. Farinosa Growth Using Scanning Electron Microscopy, Leilani Kitz Jul 2008

Evaluation Of Downy Mildew (Peronospora Farinosa F.Sp. Chenopodii) Resistance Among Quinoa Genotypes And Investigation Of P. Farinosa Growth Using Scanning Electron Microscopy, Leilani Kitz

Theses and Dissertations

Quinoa (Chenopodium quinoa Willd.) is a pseudocereal native to the Andean region of South America and a staple crop for subsistence farmers in the altiplano of Bolivia and Peru. Downy mildew is the most significant disease of quinoa caused by the pathogen Peronospora farinosa f.sp. chenopodii Byford. This disease greatly impacts quinoa crops with yield losses up to 99%. As fungicides are expensive for farmers, the development of resistant cultivars appears to be the most efficient means for controlling downy mildew. The quinoa germplasm bank contains high amounts of genetic diversity, some of which exhibit mildew resistance. Methods for evaluating …

Quinoa (Chenopodium quinoa Willd.) is a food crop cultivated by subsistence farmers and commercial growers on the high Andean plateau, primarily in Bolivia, Peru, and Chile. Present interest in quinoa is due to its tolerance of harsh environments and its nutritional value. It is thought that the seed storage proteins of quinoa, particularly the 11S globulins and 2S albumins, are responsible for the relatively high protein content and ideal amino acid balance of the quinoa seed. Here we report the genomic and cDNA sequences for two 11S genes representing two orthologous loci from the quinoa genome. Important features of the …
