Fig. 2From: Cross-talk of the biotrophic pathogen Claviceps purpurea and its host Secale cereale Principal component analysis of de novo assembled transcripts: a plant sequences and b fungal sequences. Compared were the FPKM values of the reads matching the transcripts of all four samples (mock, Cp20.1 infected, ∆cptf1 infected, ∆cpcdc42 infected) plus a reference data set for plant and fungal sequences (ref; all data points set to zero)Back to article page
