Phytopthora infestans in vitro growth and disease development after copper exposure

The data obtained in the frame of research concerning the effect of copper (Cu) on Phytophthora infestans (Mont.) de Bary. The studies were performed on two pathogen isolates, i.e., avirulent (Avr) MP946 and virulent vr MP324, in reference to the potato plant cultivar Bzura. The pathogen was growing in the presence of Cu ions for 21 days. The Cu ions were applied at two concentrations, i.e., 5 and 10 mg/L, reflecting moderate and sublethal stress, respectively. This set of data includes: Avr/vr P. infestans in vitro growth in the presence of different Cu doses Analysis of P. infestans Tef1 gene (PiTef1) expression Disease development at 72 and 96 h on potato cv. Bzura leaves The study was carried out within the project: Insight into the mechanism of the toxic effect of copper on Phytophthora infestans - the causative agent of potato late blight, no., 2021/41/N/NZ9/01525, financed by the National Science Centre, Poland.
