ABSTRACT
An Aspergillus terreus strain showed in vitro antagonistic activity against the plant pathogen Sclerotinia sclerotiorum (Lib.) de Bary. The interaction between A. terreus and sclerotia revealed that the mycoparasite sporulated abundantly on the sclerotial surface. Cell breakdown due to host cell wall disruption was observed in inner rind cells, by a scanning electron microscopy.
RESUMO
Uma linhagem de Aspergillus terreus mostrou forte atividade parasítica contra Sclerotinia sclerotiorum. Interações entre o patógeno e o antagonista revelaram que A. terreus esporulou profusamente sobre os escleródios. Quando visto em microscopia eletrônica de varredura, o antagonista mostra-se rompendo e lisando a parede celular e penetrando o interior do escleródio, onde se estabelece no tecido medular.
