WHY USE #YEAST AS A TOOL WHEN YOU'VE GOT STAGO?😁

Out now on @biorxivpreprint.bsky.social, our collab @theccdm.bsky.social led by @labkatz.bsky.social and Fran Lopez-Ruiz developed Parastagonospora nodorum as a tool to study #fungicideresistance genes.

Dissecting allele-specific fungicide resistance mechanisms by heterologous expression of the demethylase inhibitor target gene Cyp51 in a phytopathogen model
BACKGROUND Fungicide resistance is a major concern both in agriculture and clinical disease control. Whilst several mechanisms of resistance have been elucidated, assigning phenotype to genotype is of...
