Based on the gene expression profile data for the detailed developmental and infection stages of wild type P. sojae (Ye et al., 2011), we found that the expression of SP-DEGs were specifically induced during the sporangia, zoospore stages in WT, and that of IF-DEGs were relatively higher during the germinating cyst and infection stages in WT (Figure 5C). This evidence concerns the gene TFF2 and cyst.
