TFF2 and fungal infectious disease: The expression profiles of SP genes in F. fujikuroi and F. graminearum were very similar, nearly 40% of the genes were involved in the phases of penetration to biotroph fungal infection (cluster I and II of Figures 8A,B), and 50% of the genes were involved in the biotroph to necrotroph stages (cluster IV, V, and VI of Figures 8A,B).
