Characterization of Type III Effectors from Pseudomonas syringae pv. tomato DC3000

Creator:: Thireault, Caitlin
Abstract:: Many Gram-negative bacteria use a type III secretion system (TTSS) to establish a relationship with a host. Pathogens can use the secretion system as a way to deliver proteins known as type III effectors (TTEs) into a host cell and block host defense. The variation and redundancy of the type...

Analysis of the maize TOUSLED-LIKE KINASE gene family

Creator:: Yoon, Elizabeth S.
Abstract:: Protein kinases are an abundant class of enzymes which play important roles in numerous signal transduction systems. Arabidopsis TOUSLED kinase is a serine/threonine kinase which is essential for cell-cell communication within the shoot meristem. TOUSLED is encoded by a single gene in Arabidopsis. Recessive mutants in this gene show mild...

Analysis of coproporphyrinogen III oxidase in maize : the genes, their expression, and the localization of their products

Creator:: Williams, Pascale M.
Abstract:: Coproporphyrinogen III oxidase (CPX) is an enzyme involved in the biosynthesis of tetrapyrroles, catalyzing the oxidative decarboxylation of coproporphyrinogen III to protoporphyrinogen IX. In bacteria and yeast this enzyme is cytosolic, in animals it is mitochondrial, and in each it functions to produce heme. However, in all plants investigated, the...

Secreted Agrobacterium rhizogenes Effector Protein GALLS Interacts with Arabidopsis Host Proteins and Stimulates Agrobacterium-mediated Transformation

Creator:: Wei, Wei
Abstract:: Agrobacterium species transform plant cells by targeting a portion of plasmid-encoded bacterial DNA to the host nucleus. Genetic transformation by A. tumefaciens and A. rhizogenes requires secreted effector proteins. The tumor-inducing (Ti) plasmid from virulent A. tumefaciens encodes VirE2, a secreted single-stranded DNA-binding protein required for efficient transformation of hosts....

Characterization of the pathogenicity and phylogeny of members of the Rhodococcus genus

Creator:: Creason, Allison L.
Abstract:: Plant pathogenic Rhodococcus species are persistent pathogens able to cause severe growth deformities on a large range of hosts. The most well studied species, R. fascians is predicted by current models to synthesize a mixture of cytokinins that act to directly perturb the hosts' hormone balances, which results in abnormal...

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...

Genetic and physiological analysis of a light-regulated gravitropic mutant of tomato

Creator:: Gaiser, J. Christopher
Resource Type:: Dissertation

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....
