Abstract/Contents:Presents a study conducted to "incorporate fluorescent protein genes into Ophiosphaerella herpotricha"; "evaluate infection and colonization of bermudagrass cultivars by fluorescent O. herpotricha at different temperatures"; and "evaluate differences in infection and colonization among bermudagrass cultivars that vary in disease susceptibility." Explains that "spring dead spot (SDS) is the most devastating and important disease of bermudagrass that undergoes winter dormancy. This disease is caused by one or more of three fungal species in the genus Ophiosphaerella." Details methods and materials used in the study, stating that "through the insertion of genes into the fungus, transgenic isolates of O. herpotricha expressing flourescent protein genes (visualization genes) have been generated and are...used to follow root infection and colonization of various bermudagrass cultivars at different temperatures (conducive and non-conducive)." Reports that in the study "only minor root discoloration was observed around hyphae of the more resistant Midlawn cultivar. Transverse sections revealed extensive internal necrosis and infection of Jackpot and Tifway root cortices."
