Overwintering fruit structure of the fungus Aspergillus nidulans( A.
According to a study published in the journal eLife, scientists have discovered a new role for a known cell that cultivates the overwintering reproductive structure in a fungus
These findings indicate that Hülle cells also play a key role in the chemical defense strategy of the fungus Aspergillus nidulans (A.
The first author, Li Liu, a doctoral student at the University of Göttingen in Germany, explained: “As fixed organisms, fungi cannot escape attacking predators or bacteria that compete with them for resources, so they use chemical defense strategies instead.
The research team found that the proteins that produce secondary metabolites are concentrated in the fungus Hülle cells
Then, they demonstrated a regulator called the "velvet complex" that controls the production pathways of these defense chemicals
Finally, the research team exposed the fungus to small arthropod predators, including psyllids
"In short, our experiments highlight a previously unknown role of Hülle cells in protecting A.
