Pathogen-inducible expression pattern of the maize gene GRMZM2G174449 and its promoter. a Time course of GRMZM2G174449 expression after R. solani infection in 21-day-old seedlings. Asterisks indicate statistically significant differences, as determined by Student’s t-tests (*P < 0.05). b GUS histochemical staining in transgenic rice plants post inoculation with R. solani strain YWK196. c Quantitative GUS assays in transgenic rice leaves plants post inoculation with R. solani strain YWK196. Asterisks indicate statistically significant differences, as determined by Student’s t-tests (*P < 0.05)
