| Abstract/Contents: | "The aim of this study conducted at Cornell University was to determine whether Agrostis stolonifera grown in sand and soil putting green rootzones selected for different microbial communities. The composition and diversity of bacteria communities associated with the rhizosphere of ‘L- 93’ creeping bentgrass were compared using both conventional culture plating methods and modern molecular methods. The study’s findings include: Few species were detected in either sand or soil rootzones using culture-based approaches for describing rhizosphere bacterial communities [.] Isolate communities were dominated by species from genera such as Bacillus and Arthrobacter. Sand and soil rootzone isolate communities differed in type and number of taxa. Soil rootzone communities characterized by direct DNA extractions were significantly more diverse and different from sand rootzone communities; soil communities contained a high frequency of gram positive species, whereas sand communities contained a high frequency of gram negative species. Diversity of soil communities was significantly greater than that of sand rootzone communities. Results suggest a greater level of bacterial diversity than previously believed and that rootzone substrate may influence the type of microorganisms associated with bentgrass roots." |
