| Abstract/Contents: | "Three fungi in the genus Ophiosphaerella, O. herpotricha, O. korrae and O. narmari, are the causal agents of spring dead spot of bermudagrass, including zoysiagrass and buffalograss. However, the extent to which Ophiosphaerella spp. can colonize and infect different hosts is unknown. To determine to potential host range of Phiosphaerella spp. several warm-season and cool-season grasses and a dicot were evaluated for colonization by O. korrae and O. herpotricha. Plants were grown from seed under greenhouse conditions. Roots were washed with water, inoculated with either O. herpotricha or O. korrae, and incubated at 17°C. Intact and transverse sectioned roots were examined under a fluorescence microscope at 2 to 14 days after inoculation. The interaction with different plant species was similar for both fungal species. In creeping bentgrass, the fungi was able to colonize the root vasculature without causing necrosis. In zoysiagrass and buffalograss, the fungi occasionally caused necrosis of the root cortex, but did not colonize the vasculature. Prosso millet and blue panicgrass exhibited cortical colonization, but no visible necrosis. Broadleaf panicum, big bluestem and alfalfa were non-hosts, with minimum root surface colonization. Ophiosphaerella spp. appear to have a broader host range than previously recognized, though many of the plant-fungus interactions do not result in disease-associated necrosis." |
