We herein describe the methods for RNA induction, extraction, and quality determination, and the RT-PCR conditions used to evaluate the ability of a given Aspergillus strain to produce aflatoxins.engbook parthttps://link.springer.com/book/10.1007%2F978-1-4939-6707-0restricted access582.282.123.4575615.372Aspergillus flavusMycotoxinsAflatoxigenic fungiRNA extractionRT-PCRGel electrophoresisBiologíaGenéticaMicrobiología (Biología)24 Ciencias de la Vida2409 Genética2414 Microbiología
