Genome-Wide Characterization Of Lateral Organ Boundaries Domain Genes In Sunflower (Helianthus Annuus L.), Saleh M. Aljurbua Jan 2021

Genome-Wide Characterization Of Lateral Organ Boundaries Domain Genes In Sunflower (Helianthus Annuus L.), Saleh M. Aljurbua

Masters Theses

Lateral Organ Boundaries (LBD) gene family encodes transcription factors found only in plants with essential roles in growth, development, and response to biotic and abiotic factors. The sunflower (Helianthus annuus L., Asteraceae family) LBD genes were studied using different in silico and phylogenetic approaches including four major steps: gene identification, phylogenic analysis, structural analysis, and expression analysis. Sixty-four sunflower LBD genes (HaLBDs) were identified using query search of all Arabidopsis LBD genes against sunflower genome (version r1.2) followed by LBD domain sequence verification. A phylogenetic tree was reconstructed using MEGA-X program. The identified genes were phylogenetically classified into two main …


Molecular Systematics Of The Subfamily Phasiinae (Diptera: Tachinidae), Jeremy Daniel Blaschke Aug 2013

Molecular Systematics Of The Subfamily Phasiinae (Diptera: Tachinidae), Jeremy Daniel Blaschke

Masters Theses

The subfamily Phasiinae (Diptera: Tachinidae) is composed of obligate endoparasitoid flies that attack heteropteran insects, many of which are important agricultural pests. To lay a foundation for future studies in phasiine life history and their potential for use as biological control agents, the phylogenetic relationships within Phasiinae were explored using nucleotide sequences of two genes, CAD and LGL. A total of 63 taxa for CAD and 73 taxa for LGL were included in the analyses, representing 58 genera. Maximum likelihood inference methods were employed to reconstruct phylogenetic relationships in separate analyses of each gene and in a combined dataset. Phylogenetic …
