Molecular genetic characterization of a pathogenicity-attenuated mutant of Pseudomonas syringae pathovar syringae

Creator:: Zhao, Yuqi
Abstract:: A pathogenicity locus of Pseudomonas syringae pv. syringae identified by Tn5 mutagenesis was investigated. The mutant strain PS9024 is attenuated for disease expression in its host, Phaseolus vulgaris, but produces the hypersensitive reaction (HR) in the nonhost, tobacco (Nicotina tabacum). A cosmid clone carrying 16 kilobases (kb) of contiguous genomic...

Molecular characterization of the MX genes of rainbow trout (Oncorhynchus mykiss)

Creator:: Trobridge, Grant David
Abstract:: The Mx protein family of rainbow trout (Oncorhynchus mykiss) was characterized at the molecular level. With primers derived from a partial sequence of Perch (Perca fluviatis) Mx genomic DNA, a partial rainbow trout Mx genomic DNA sequence was obtained by polymerase chain reaction (PCR) amplification. All salmonid fish investigated contained...

Molecular cloning and characterization of the diageotropica gene in tomato (Lycopersicon esculentum Mill.)

Creator:: Oh, KwangChul
Abstract:: The auxin-resistant diageotropica (dgt) mutant of tomato (Lycopersicon esculentum Mill.) has a pleiotropic phenotype including a lack of lateral roots and reduced gravitropic response, apical dominance, vascular development, and fruit growth. The dgt mutation reduces the auxin sensitivity of only a subset of auxin responses while levels, metabolism, and transport...

Characterization of Neurospora crassa and Fusarium graminearum mutants defective in repeat-induced point mutation

Creator:: Pomraning, Kyle R.
Abstract:: Mutation of repetitive DNA by repeat-induced point mutation (RIP) is a process that occurs in many filamentous fungi of the Ascomycota during the sexual cycle. Concurrently, direct DNA repeats are often deleted by homologous recombination at high frequency during the sexual cycle. Thus, the processes of RIP and deletion compete...

Phylogenetic Studies in Tenebrionidae (Coleoptera) and Related Families

Creator:: Kanda, Kojun
Abstract:: In this dissertation, I present the results from three studies: (1) a phylogeny of Tenebrionoidea (Coleoptera) inferred from a seven-gene dataset derived from PCR and Sanger sequencing; (2) a phylogeny of Tenebrionidae, the largest family in Tenebrionoidea, inferred from a four-gene dataset also derived from PCR and Sanger sequencing; (3)...

Origins and evolution of plant microRNA genes

Creator:: Fahlgren, Noah
Abstract:: Eukaryotic small RNA (~20-30 nucleotides) are diverse regulatory molecules that repress gene expression at the transcriptional and post-transcriptional levels, defend hosts against invading viruses and defend genomes against selfish DNA elements. Small RNA populations are studied by high-throughput sequencing of the total small RNA fraction isolated from cells, however, the...

Molecular and physiological aspects of maize embryo maturation

Creator:: White, Constance N.
Abstract:: Experiments were performed to assess regulatory factors governing maize embryo maturation and vivipary. Both visual and molecular markers of embryo development were used to examine the roles of the hormones abscisic acid (ABA) and gibberellins (GAs), as well as water stress in governing transit from early embryogeny to maturation-phase development....

The development and analysis of sequence-based DNA markers in sunflower for DNA fingerprinting and candidate gene analysis

Creator:: Hongtrakul, Vipa
Abstract:: Molecular DNA markers have become widely used in all areas of genetic research. The objectives of this thesis were to develop polymorphic markers in sunflower and utilize the markers for genetic and candidate gene analyses. Amplified fragment length polymorphism (AFLP) markers were used to estimate genetic similarities and assess the...
