| Abstract/Contents: | "Bermudagrass Decline (BD) is a disease that affects ultradwarf bermudagrass (UDB). Putting greens across the southeastern United States and the transition zone have suffered from BD as research efforts continue to understand the complexitites of this disease. This research will address the what, when, where, and who associated with BD. We propose a complex of ectotrophic root-infecting (ERI) fungi colonize symptomatic/asymptomatic roots of UDB. Two UDB greens at Mississippi State University Golf Institute were selected to conduct this study. One green was symptomatic for BD and the other asymptomatic. A fishnet grid was designed using ArcGIS to overlay each green to establish areas of interest (AOI). A 2017 summer core aerification provided root material for each AOI to detect and quantify ERI fungi using genomic DNA and multiplex qPCR. Fungi of interest included G. graminis (Gg) (the causal agent of BD), an undescribed G. sp. (Gsp), Magnaporthiopsis cynodontis (Mc), and the novel Candidacolonium cynodontis (Cc). A four-fungal complex was present in 8% of AOIs within the BD green and 7% within the asymptomatic green. Gg was widely distributed in the BD green but identified in less than 25% of AOIs in the asymptomatic green. Mc was the most predominant fungus in both greens. Gsp and Cc were identified more frequently in the asymptomatic green. The number of DNA copies of Gg were significantly greater in the BD green than in the asymptomatic green. DNA copies of Gg were significantly greater than the other selected ERI fungi in the BD green. No difference in number of DNA copies were noted among the selected ERI fungi in the asymptomatic green. These results indicate Gg plays a major role in BD. The role of the remaining ERI fungi is yet to be determined." |
