When a pathogen pushes into a cell already occupied by a symbiotic fungus, things change. New membrane phospholipids at pathogen haustoria! This may impact immune receptor positioning & defense secretion. -
And the roots are more resistant!

Looking for a postdoc on bacterial-insect symbiosis, combining evolution and molecular mechanisms? I'll have one open in my lab starting Sept 2025. If interested contact me (or find me at the GRC on Animal-microbe symbiosis if you'll be there). #SymbioSky

This is already shaping up to be one of the best gatherings I'm co-organising with @michaelraissig.bsky.social - & I think it'll stay that way for a while.

Hsc70-4: An unanticipated mediator of dsRNA internalization in Drosophila Hsc70-4 localizes to the cell surface of Drosophila cells, binds to exogenous dsRNA, and mediates its internalization.

Stop for a second and try to imagine this: a heat shock protein relocalizes to the cell surface and mediates dsRNA binding and internalization!
