NaPDR1 and NaPDR1-like are essential for the resistance of Nicotiana attenuata against fungal pathogen Alternaria alternata.

ABSTRACT: Pleiotropic drug resistance (PDR) transporters are widely distributed membrane proteins catalyzing the export or import of a diverse array of molecules, and are involved in many plant responses to biotic and abiotic stresses. However, it is unclear whether PDRs are involved in Nicotiana attenuata resistance to the necrotic fungal pathogen Alternaria alternata. In this study, transcriptional levels of both NaPDR1 and NaPDR1-like were highly induced in N. attenuata leaves after A. alternata inoculation. Interestingly, silencing NaPDR1 or NaPDR1-like individually had little effect on N. attenuata resistance to A. alternata; however, when both genes were co-silenced plants became highly susceptible to the fungus, which was a
