| Abstract/Contents: | "Activities of key enzymes of N-assimilation were determined in KY-31 tall fescue infected with Sphacelia typhina (=Acremonium coenophialum) and in endophyte free plants grown under high and low NO3 and NH3 fertilization conditions. NO3 reductase and glutamine synthetase activities in leaf sheaths and blades were higher in infected plants than in uninefected plants under all N conditions, while glutamate dehydroganase activities (NADH and NADPH) were low or not detectable in any case. Although total NO3 did not differ, NH4+ levels were elevated in infected plants and NH3 evolution in detached infected and uninfected leaves was dependent on exogenous amino acids. Quantitative and qualitative changes in amino acid composition were also observed in infected plants. Increased enzyme activity in leaf blades of infected plants into which fungal hyphae do not penetrate indicated infection increased N-assimilation while changes in NH4+, NH3 evolution and amino acids indicated altered N-metabolism." |
