| Abstract/Contents: | "A common plant pathogen, Acidovoraxavenae subsp. avenae (Aaa) has recently been found in association with an emerging disease on creeping bentgrass (Agrostis stolonifera L.) causing unique symptoms of etiolation and decline. First reported in 2010, Aaa has since been isolated out of more than 20 different symptomatic golf course samples. Identification via 16S rDNA sequencing and inoculation studies have confirmed pathogenesis of Aaa on creeping bentgrass. Temperature range studies show disease progression to be most severe at 30-35°C under high relative humidity. All creeping bentgrass cultivars inoculated thus far with 2.0 x 108 CFU of Aaa have been susceptible o infection when compared to sterile buffer control inoculated plants. Field studies and subsequent growth chamber studies on creeping bentgrass were conducted in order to elucidate potential chemical management options. Oxytetracycline pre-treated at 200 ppm significantly reduced leaf necrosis, discoloration, and thinning after inoculation with Aaa at 2.0 x 108 CFU compared to an untreated, inoculated control (P < 0.001). This is the first study elucidating Aaa infection on a commodity turfgrass in the United States. Genetic characterization of Aaa to closely related plant pathogenic Acidovorax spp. via multi-locus sequence typing (MLST) is underway with plans for genome sequencing of the turfgrass pathogen and the development of a molecular diagnostic assay." |
