Principal component analysis (PCA) plot of the transcript per million (TPM) counts. The trends exhibited by the expression profiles of the RNA extraction and sequencing platform protocols (CTAB/Illumina, Zymo Research/Illumina, CTAB/Ion Torrent, Zymo Research/Ion Torrent) are displayed for the reference gene TPM counts in a and for the pathogen TPM counts in b. Samples are indicated with colours correlating to extraction method and sequencing platform and each colour circle represents a cluster of these designations
