Expression profiling of Phytophthora genes during infection. a Expression of stage-specific genes HMP1, NPP1 and CDC14 upon inoculation of MsK8 cells with zoospores of P. infestans 14-3-GFP (Pi), P. capsici LT263 (Pc), P. palmivora GFP3 (Pp) and P. sojae P6497 (Ps). b Expression of IPI-B and various P. infestans RXLR effector genes upon inoculation of MsK8 cells with zoospores of P. infestans 14-3-GFP. Expression levels were determined by qRT-PCR and the values at each time point were calculated relative to the expression level at time point 0 (0 hpi). Expression of the actin gene ActA was used as endogenous control
