The HOG-pathway related AaOS1 leads to dicarboximides-resistance in field strains of Alternaria alternata and contributes together with the Aafhk1 to mycotoxin production and virulence.

To our knowledge, this is the firstly report about the Pro-resistance selected in the garlic fields, and mutations at AaOS1 of A. alternata causing the decreased ability to produce the mycotoxin AOH. This article is protected by copyright. All rights reserved.
