Diffuse Interactions Between Symbiotic Bacteria And Salamanders, Amanda Lee Allison
Diffuse Interactions Between Symbiotic Bacteria And Salamanders, Amanda Lee Allison
Masters Theses
A growing body of evidence indicates that all animals and plants have intimate associations (symbioses) with microbes. Scientific opinion has shifted from viewing microbes primarily as pathogens to the idea that healthy animals and plants carry specialized communities of coevolving microorganisms. However, the generality of this proposition is unknown because surveys rarely compare host-associated microbial assemblages with those of similar host species or free-living assemblages in relevant microhabitats. To evaluate the specificity and consistency of microbial associations in salamanders, I analyzed just over 3.6 million 16S ribosomal RNA gene sequences from paired samples from host-associated bacteria on the skin of …
Molecular Marker Assisted Development And Stability Analysis Of Low Phytate, High Inorganic Phosphorus Soybean [Glycine Max (L.) Merrill], Suzannah Joy Wiggins
Molecular Marker Assisted Development And Stability Analysis Of Low Phytate, High Inorganic Phosphorus Soybean [Glycine Max (L.) Merrill], Suzannah Joy Wiggins
Masters Theses
Phytate [myo-inositol 1,2,3,4,5,6-hexakisphosphate] is a mixed cation salt of phytic acid which binds to other minerals, in many field crops including soybean [Glycine max (L.) Merr.]. Livestock with monogastric digestive systems lack the ability to break bonds between phytate and these minerals, causing phytate phosphorus (P) to be excreted in the waste and contributing to possible P and other mineral deficiencies. Discovery of single sequence repeat (SSR) and single nucleotide polymorphism (SNP) markers associated with low phytate QTL (cqPha-001 and cqPha-002) have aided in development of low phytate soybean lines. The objectives of this study were …
Studies On Enzyme Functional Evolution In The Sabath Multigene Family Using Phylogenetic And Biochemical Approaches, Ruiqi Huang
Studies On Enzyme Functional Evolution In The Sabath Multigene Family Using Phylogenetic And Biochemical Approaches, Ruiqi Huang
Masters Theses
Gene duplication is believed to be the major source for providing genetic materials for the innovation and diversification of protein functions; natural selection and/or neutral drift then works on these genetic materials to guide their evolutionary directions. Here, I used the salicylic acid/benzoic acid/theobromine (SABATH) multigene family to study how natural selection acted on duplicated genes to prompt functional diversification. Members in this family methylate plant secondary metabolites by transferring the methyl group from S-adenosyl-L-methionine (SAM) to the carboxyl group or ring nitrogen of the substrates. In the Apocynaceae and Solanaceae lineage of this family, I documented three putative gene …
