Abstract

Lecanicillium fungicola causes dry bubble disease and is an important problem in the cultivation of Agaricus bisporus Little is known about the defense of mushrooms against pathogens in general and L fungicola in particular In plants and animals a first attack by a pathogen often induces a systemic response that results in an acquired resistance to subsequent attacks by the same pathogen The development of functionally similar responses in these two eukaryotic kingdoms indicates that they are important to all multicellular organisms We investigated if such responses also occur in the interaction between the white button mushroom and L fungicola A first infection of mushrooms of the commercial A bisporus strain Sylvan A15 by L fungicola did not induce systemic resistance against a subsequent infection Similar results were obtained with the A bisporus strain MES01497 which was demonstrated to be more resistant to dry bubble disease Apparently fruiting bodies of A bisporus do not express induced resistance against L fungicola
