| Abstract/Contents: | "Ophiosphaerella herpotricha is one of the causal agents of spring dead spot in turftype bermudagrass (Cynodon spp. and interspecific hybrids) in the transition zone of the United States. Isolates of O. herpotricha were transformed using Agrobacterium tumefaciens to express either green (GFP) or red (tdTomato) fluorescent protein. Two turftype cultivars, Tifway 419 and Midlawn and a Cynodon transvaalensis accession were used to study the infection and colonization of roots by O. herpotricha under controlled conditions. Roots were inoculated with fungal mycelium and plants were incubated at 17°C. At 2 DPI (days postinoculation), transverse and longitudinal sections revealed fungal penetration through intact root epidermal layers for all plants. At 10 DPI, O. herpotricha colonized root cortical tissues of Tifway 419 and Midlawn intracellularly, formed aggregated hyphae, and caused necrotic lesions and collapse of cortical cells. At 14 DPI, roots of Midlawn and Tifway 419 exhibited a range of necroses while roots of C. transvaalensis were much less necrotic and appeared tolerant to infection by O. herpotricha." |
