Identification and deletion of Tft1, a predicted glycosyltransferase necessary for cell wall β-1,3;1,4-glucan synthesis in Aspergillus fumigatus.

Aspergillus fumigatus is an environmental mold that causes severe, often fatal invasive infections in immunocompromised patients. The search for new antifungal drug targets is critical, and the synthesis of the cell wall represents a potential area to find such a target. Embedded within the main β-1,3-glucan core of the A.

Targeted gene deletion in Aspergillus fumigatus using microbial machinery and a recyclable marker.

The emerging invasive fungal pathogen Aspergillus fumigatus causes very serious infections among immunocompromised patient populations. While the genome of this pathogen has been sequenced, a major barrier to better understanding the complex biology of this eukaryotic organism is a lack of tools for efficient genetic manipulation. To improve upon this, we have generated a new gene deletion system for A.
