| Abstract/Contents: | "Gaeumannomyces graminis var. graminis (Ggg) is an ectotrophic root-infecting (ERI) fungus characterized by presence of runner hyphae and hyphopodia on the outer surface of roots and stolons. Ggg is considered to be the primary causal agent of bermudagrass decline; however, six novel species of ERI fungi associated with bermudagrass decline have recently been identified. Of those, G. paulograminis was morphologically and molecularly distinct from Ggg. A concern for golf course superintendents is how these pathogens disseminate since vegetative propagation is the sole source of 'MiniVerde', 'TifEagle', and 'Champion' cultivars. Sod of these cultivars were obtained from sod farms in the southeastern U.S. Soil was washed from roots of sod samples which were shredded into sprigs and planted into sterile sand in 7.6 cm diameter containers. Each treatment (Cultivar/origin) had ten replicates maintained in a growth chamber at 30°C and 12 hr light cycle and watered to prevent desiccation. After 8 weeks, all plants were examined for signs of ERI fungi. Colonized plant material was surface disinfested and plated onto water agar. Hyphal tips were transferred to potato dextrose agar. Genomic DNA was extracted from colonies for identification based on the internal transcribed spacer region. The ERI fungus typically identified as Ggg based on hyphopodia was an identical match to G. paulograminis originating from MiniVerde and Champion cultivars from two different states." |
