As shown in Fig. 6a–d, OX398b lines display significantly decreased levels of CSD1, CSD2 and CSD3 with or without blast treatment, indicating that overexpression of miR398b leads to lower CSD expression; upon Guy11 infection, nearly all mutants lines displayed less or unchanged mRNA amounts of the four CSDs, suggesting that M.oryzae suppressed CSD expression. Here, TGFBI is linked to infection.
