The Foliose Bangiales (Rhodophyta) In The Northern Part Of The North Atlantic And The Relationship With The North Pacific Foliose Bangiales - Diversity, Distribution, Phylogeny And Phylogeography, Agnes Mols-Mortensen Jan 2014

The Foliose Bangiales (Rhodophyta) In The Northern Part Of The North Atlantic And The Relationship With The North Pacific Foliose Bangiales - Diversity, Distribution, Phylogeny And Phylogeography, Agnes Mols-Mortensen

Doctoral Dissertations

Foliose Bangiales species have a long history of study in the North Atlantic, but regions, especially in the northern parts, need more attention. Based on both new collections and herbarium material from Iceland, the Faroe Islands, West Greenland, UK, Norway, Sweden, Denmark and the Northwest Atlantic coast (from Newfoundland to Florida) the aim was to document diversity and distribution of foliose Bangiales species in the North Atlantic and to make floristic comparisons between the geographical areas. Species Identification was based on DNA sequences using the mitochondrial cox1, chloroplast rbcL and 3' rbcL + 5' rbcL-S markers. The North Atlantic species …


Development Of Genomic Resources And Identification Of Marker-Trait Associations In Strawberry, Lise L. Mahoney Jan 2014

Development Of Genomic Resources And Identification Of Marker-Trait Associations In Strawberry, Lise L. Mahoney

Doctoral Dissertations

Crosses were performed and progeny populations were developed in diploid and octoploid strawberry (Fragaria) species for the purposes of genetic analysis and breeding. A high throughput genotyping platform - the Affymetrix IStraw90® Axiom® strawberry SNP array - was evaluated and employed for these purposes. Phenotyping was conducted with respect to several traits of interest, including flower color, flower and fruit pigment compositions, and verticillium wilt resistance, for the ultimate purpose of identifying marker-trait associations useful in breeding. In the ancestral diploid species Fragaria iinumae, an F2 mapping population was developed from a cross between two accessions previously collected in Hokkaido, …
