Abstract

Peroxidase and polyphenoloxidase isoenzymatic expression was studied in Sorghum bicolor roots, inoculated with six arbuscular mycorrhizal fungus species belonging to Glomus genus, two and three months after seed germination. Fungal colonization and visual density percentages were determined, obtaining high values in both cases, it confirming that symbiosis was adequately established. In general, different electrophoretic patterns were observed in both systems analyzed, taking into account the evaluation time and mycorrhizal species used, in which seven peroxidase and three polyphenoloxidase isoforms were detected. The three-month peroxidase system showed the highest polymorphism; Glomus mossae and Glomus claroideum species being remarkable.
