Effect of DMI-resistance mechanisms on cross-resistance patterns, fitness parameters and aflatoxin production in Aspergillus parasiticus Speare

► Characterization cyp51, mdr and aflR genes in DMI resistant strains of Aspergillus parasiticus. ► Expression of aflR gene in toxigenic and non-toxigenic DMI-resistant strains of A. parasiticus. ► Different DMI-resistance mechanisms affect cross resistance and aflatoxin production in A. parasiticus. ► Relationships between DMI-resistance phenotype, fitness parameters and aflatoxin production.
