Genome-enabled discovery and characterization of type III effector-encoding genes of plant symbiotic bacteria

Creator:

Kimbrel, Jeffrey A.

Abstract:

Symbiosis is the close and protracted interaction between organisms. The molecular interactions that occur during symbiosis are complex with multiple barriers that must be overcome. Many Gram-negative, host-associated bacteria use a type III secretion system to mediate associations with their eukaryotic hosts. This secretion system is a specialized apparatus for...

Pyoluteorin as a signaling molecule regulating secondary metabolite production and transport genes in Pseudomonas fluorescens Pf-5

Creator:

Brodhagen, Marion L.

Abstract:

A major factor in the ability of Pseudomonas fluorescens Pf-5 to act as a biological control agent is its production of antibiotics, including pyoluteorin (PLT), 2,4-diacetylphloroglucinol (2,4-DAPG) and pyrrolnitrin (PRN). The data provided in this thesis demonstrate that the presence of any of these antibiotics in the extracellular milieu affects...

Analysis of flavor precursors in radish and radish color extracts

Creator:

Kucza, Myriam M.

Abstract:

Radish anthocyanin extract has potential as a natural colorant because of its pigment stability and attractive red hue. Presence of undesirable aroma compounds could limit its applications in foods. The pungent principle of radish, 4-methylthio-3-butenyl isothiocyanate (MTBI), is produced enzymatically upon cell injury from its glucosinolate precursor, 4-methylthio-3-butenyl glucosinolate (MTBG),...
