Última NEW PERSPECTIVES ON THE DETERMINATION OF PHOSPHATASE ACTIVITY IN ECTOMYCORRHIZAE OF NOTHOFAGUS OBLIQUA FORESTS IN SOUTHERN CHILE Gayana Botánica Alvarez,Maricel; Härtel,Steffen; Godoy,Roberto; Heyser,Wolfgang. We present a method to localise and quantify surface-bound phosphatase activity (SBPA) in mycorrhizal fungi and mycorrhizae of Nothofagus obliqua (Mirb.) Oerst., using image processed confocal fluorescent microscopy. ELF-97 is a hydrophilic substrate which turns into a strongly fluorescent precipitate upon activation by phosphomonoesterases. In fungal mycelium, this technique has recently been approved by comparison with a standard method (p-nitrophenyl-phosphate). The microscopic technique based on ELF-97 revealed that Paxillus involutus (Batsch: Fr.) Sing. and Austropaxillus boletinoides (Sing.) Brsky. & Jarosch provide different adaptive strategies to changing phosphate concentrations and different pH (3-7). We also analysed SBPA in four...
