PPOX and infection: Real-time quantification was also conducted on the 14 GhPPO genes in the CCRI36 and MBI8255 roots, under the same situation as the transcriptome experiment (Figure 7), for which the qRT-PCR results of 10 GhPPOs showed a high consistency with the RNA-seq data, indicating the reliability of the dramatic changes of the PPO genes when responding to VW infection.
