**8. Fungal transporters**

Transporters are of great importance in protecting fungi against plant defense compounds. Transporters enable efflux of the plant-originated defense compounds. Although resveratrol (from grape) and camalexin (from Arabidopsis) transport via the transporter BcatrB of *Botrytis cinerea*, pisatin (from pea) transports by the NhABC1 transporter of *F. solani* f. sp. *pisi*, and rishitin (from potato) transports via the GpABC1 transporter of *F. sambucinum* [4, 49–51].

Transporters are divided into two major classes: the ATP-binding cassette (ABC) and the major facilitator superfamily (MFS) transporters. ABC transporters are known to be important for resistance against fungal pathogens, particularly for pleiotropic drug resistance or multidrug resistance domains [52]. Although some transporters produce specific or non-specific toxins, some of them show very specific responses to fungicide sensitivity or resistance [53].
