Brassicales to Brassica : integrating phylogenomics and population genomics
(University of Missouri--Columbia, 2020)
populations. Using this system of diversity within domesticated B. oleracea, I examined patterns of relationships among morphotypes, including signals of hybridization and introgression. Brassica oleracea vegetable crops are frequently regarded as superfoods...
Mechanisms of polar growth in the alphaproteobacterial order rhizobiales
(University of Missouri--Columbia, 2019)
characterized a comprehensive set of cell wall synthesis enzymes in A. tumefaciens and identified penicillin-binding protein 3a (PBP3a) and PBP3b as a synthetic lethal pair that function during cell division, and PBP1a as an essential enzyme required for polar...
The molecular underpinnings of neuronal cell identity in the stomatogastric ganglion of cancer borealis
(University of Missouri--Columbia, 2019)
Throughout the life of an organism, the nervous system must be able to balance changing in response to environmental stimuli with the need to produce reliable, repeatable activity patterns to create stereotyped behaviors. Understanding...
Insights into phototropic signaling : a study of the unusual attributes of a hyper-phototropic mutant
(University of Missouri--Columbia, 2008)
on these discoveries we then began to address the molecular aspects of hph through the use of transgenic plants and, subsequently, other tools to decipher the proteinprotein interactions (Ch. 3). To conclude, we have initiated an ecological study focused...
