Tryptophan dimer (Trp-Trp) as an attractant for Gi. margarita and G. caledonium. a Trp-Trp in the paper disk with twine ring attracted the hypha of AM fungi to the circle zone. b The spores of Gi. margarita or G. caledonium were separately placed 10 or 20 mm from twine ring. c The hypha attracted by Trp-Trp coiled around the circle zone with twine ring. The treatments were performed for 14 days in the dark. d Bar 1 mm
