| Abstract/Contents: | "Infection of tall fescue Festuca arundinacea, with the endophytic fungus, Neotyphodium coenophialum, is correlated with increased resistance to preemergence damping-off caused by Rhizoctonia zeae, R. solani and Pythium aphanidermatum. The objective of this research was to determine if selected enzymes were affected by endophyte infection and/or germination. Genetically similar seed lots with either a 95% endophyte infestation level (E+) or a 0% infection level (E-) were scarified and soaked in sterile water. Seed were ground in liquid nitrogen and extracted with buffer. Enzyme activities were determined with standard protocols. Peroxidase activity, monitored at various intervals between 9 and 24 h, was significantly different betwee E+ and E- at all times; the rate of increase was also greater for E+ then E- treatments. Catalase and superoxide dismutase activities were determined only at 0 and 24 h. Catalase activity was greater at 24 h than at 0 h, but there were no differences between E+ and E- treatments. Preliminary results for superoxide dismutase suggest trends similar to catalase." |
