Nutrients for a rust fungus: the role of haustoria

Haustoria are specialized organs that are formed within the living cell of a host by biotrophic fungal pathogens. It had been speculated that fungi obtain nutrients via the haustorium, but the actual function of haustoria was unclear. Now, sugars have been shown to pass into the haustorium from the...

Zusammenfassung:	Haustoria are specialized organs that are formed within the living cell of a host by biotrophic fungal pathogens. It had been speculated that fungi obtain nutrients via the haustorium, but the actual function of haustoria was unclear. Now, sugars have been shown to pass into the haustorium from the host via a sugar transporter, a hexose-proton symport located exclusively in the haustorial plasma membrane.
