Characterizing gene expression responses to colchicine in Dactylis smithii

Fleet, Paige Miriam (Halifax, N.S. : Saint Mary's University, 2017)

Tetraploid plant species are preferred in certain agricultural cases over their diploid counterparts for larger biomass and increased resistance to abiotic stresses. Naturally occurring tetraploids are thought to result ...
The effectiveness of Halifax-produced 18FDG-PET/CT in the evaluation of patients with solitary pulmonary nodule or suspected lung cancer and the impact on patient management

Rajaraman, Shane A. (Halifax, N.S. : Saint Mary's University, 2013)

Integrated Positron Emission Tomography and Computerized Tomography (PET/CT) is a powerful imaging technique that combines functional and anatomical information for early and accurate detection of cancer. Limited availability ...
Evaluation of gene expression responses to colchicine in Dactylis smithii at different tissues

Scarrow, Maggie (Halifax, N.S. : Saint Mary’s University, 2018)

Environmental stresses have had a major impact on gene expression and evolutionary adaptation as a whole. What has been discovered is that polyploids have a genetic advantage compared to their diploid relatives in allele ...
Evolution and origin of polyploid Triticeae (Poaceae) revealed through the nuclear pgk1 gene

Adderley, Shawn James (Halifax, N.S. : Saint Mary's University, 2013)

Despite many studies on the taxonomy of the Triticeae, no general consensus has yet been agreed upon as to their phylogenetics. This is attributed to extremely high rates of hybridization and polyploidization. Levels of ...
Fusarium head blight and deoxynivalenol from barley in the Maritime Provinces

Halliday, Emma E. (Halifax, N.S. : Saint Mary's University, 2020)

Fusarium Head Blight (FHB) is one of the most devastating agriculture diseases that affects barley worldwide by reducing crop yields and grain quality. The main causal organism of concern in Eastern Canada is the fungal ...
Gene expression in response to salt stress mediated by genome doubling in Hordeum bulbosum

Wright, Alexandra L. (Halifax, N.S. : Saint Mary's University, 2023-05-01)

Soil salinity impacts crop plants globally and can lead to the death of the plant due to incapacitation of cellular processes. To increase survival, plants have evolved many adaptation mechanisms to tolerate salt stress ...
Genetic diversity of the DREB1 gene in Hordeum vulgare and Hordeum spontaneum

Hicks, Taylor (Halifax, N.S. : Saint Mary's University, 2019)

Environmental stresses often disrupt and alter the growth of plants and their life cycles. This causes molecular responses to upregulate gene expression, inducing important stress responsive genes. Dispersal and continuous ...
Genetic relationship of Elymus alaskanus, E. caninus, E. fibrosus, and E. mutabilis revealed by chloroplast DNA sequences

Joyce, Adele Catherine (Halifax, N.S. : Saint Mary's University, 2014)

The genetic diversity of a species measures its genetic variation, or population diversity, which determines evolutionary relationships; high genetic diversity is linked to survival, adaptation and evolution. In this study, ...
Molecular phylogeny of the RPB2 gene in five Elymus species with the StH genome

Purvis, Katherine Irene (Halifax, N.S. : Saint Mary's University, 2020)

Elymus is a polyploid genus within the grass tribe (Triticeae) and is thought to have originated from the hybridization between species in other Triticeae genera. As Elymus originated from processes such as hybridization ...
Nucleotide diversity and genetic relationships of orchardgrass (Dactylis glomerata) inferred from two non-coding regions of the chloroplast

Hamstra, Troy (Halifax, N.S. : Saint Mary's University, 2016)

Orchardgrass (Dactylis glomerata L.), an important member of the Poaceae family, is a cool-season perennial forage grass, and is widely used for hay production throughout temperate and subtropical regions of the world. ...
Phylogenetic analysis of the genus Pseudoroegneria and the Triticeae tribe using the rbcl gene

Gamache, Jacques (Halifax, N.S. : Saint Mary's University, 2013)

Pseudoroegneria are diploid perennial grasses of the Triticeae tribe. The haplome “St” of Pseudoroegneria is shared with several important polyploid species such as Elymus, Kengyilia and, Elytrigia. Due to frequent ...
Salt stress response single genes expression in diploid and autopolyploid Hordeum bulbosum

Cheng, Zhilan (Halifax, N.S. : Saint Mary's University, 2021)

Soil salinity is a worldwide problem, which hinders the growth of crop yields and brings great challenges to the world. To deal with the reduction of agricultural land, research and cultivating the development of salt-tolerant ...
