Activation of defence responses to Phytophthora infestans in potato by BABA

Late blight caused by Phytophthora infestans is one of the most devastating diseases of the potato crop. Resistance breeding and current fungicides are unable to control the rapidly evolving P. infestans and new control strategies are urgently needed. This study examined mechanisms of DL-b-aminobutyric acid (BABA)-induced resistance (IR) in the potato–P. infestans system. Leaves from two cult…
