Kind: research · Impact: low

## In brief

- Researchers identified a fungal effector, NFC1, that is necessary for root colonization by the conditional plant pathogen C. tofieldiae.
- NFC1 also contributes to perturbing the host's circadian clock.
- NFC1 is tightly suppressed under phosphate deficiency by the fungal transcription factor CtPHO4.

## Why it matters

The work links the fungus's nutrient-sensing system to its ability to infect plant roots, which helps explain how nutrient status shapes plant-microbe interactions.
