Salt treatments enhance the blast disease resistance of rice leaves. a Phenotype of rice plants (Nipponbare) under salt and Guy11 treatments. Rice seedlings were treated with 50 mM and 100 mM NaCl for 24 h and then spray-inoculated with conidial suspensions (1 × 10⁵ conidia/mL in 0.02% Tween 20) of M. oryzae. Images were taken at 5 dpi. b, c Estimation of lesion number and fungal biomass in a. The fungal biomass was determined by qPCR of M. oryzae Pot2 gene against the rice OsACTIN gene. Values are mean ± SE. Significant differences from the WT were analyzed using Student's t-test (** p < 0.01)
