Puccinia
Puccinia is a genus of rust fungi that parasitize plants, causing diseases in crops like wheat, corn, and various grasses.
The fungi produce characteristic rusty-orange or brown pustules on infected leaves and stems.
Wheat rust caused by Puccinia species has devastated harvests throughout agricultural history and remains a significant threat to global food production.
