Mycorrhizal Fungi and Plant Interactions

Trametes versicolor (L.: Fr) Pilat was identified causing white rot of hardwood tree species of amate amarillo (Ficus petiolaris), cuatecomate or cirian (Crescentia alata), guayava (Psidium guajava) and sauce colorado (Salix humboltiana) in municipalities of Ayala, Cuautla, Cuernavaca, Jojutla Tepalcingo Tlaltizapan, Tlaquiltenango and Zacatepec de Hidalgo in the state of Morelos, Mexico. Collected strains were grown in water-agar culture medium with 2,4-D amine at concentrations of 0, 50, 100, 150, 250, 500, 1000, 2000, 3000, 4000 and 5000 ppm with the aim of know their growth in this salt. The best results were found from 50 to 1000 ppm concentration with an optimum from 500 to 1000 ppm. Concentrations from 2000 to 5000 ppm inhibited fungal growth. The strains of T. versicolor can be used as a potential tool of bioremediation of water contaminated by 2,4-D which is wide used as a herbicide to control of broadleaf weeds in corn, rice, sugarcane and sorghum in the studied region.
