Title The DnaJ protein OsDjA6 negatively regulates rice innate immunity to the blast fungus Magnaporthe oryzae.
Rice blast, caused by Magnaporthe oryzae (synonym: Pyricularia oryzae), severely reduces rice production and grain quality. The molecular mechanism of rice resistance to M. oryzae is not fully understood. In this study, we identified a chaperone DnaJ protein, OsDjA6, which is involved in basal resistance to M. oryzae in rice. The OsDjA6 protein is distributed in the entire rice cell. The expression of OsDjA6 is significantly induced in rice after infection with a compatible isolate. Silencing of OsDjA6 in transgenic rice enhances resistance to M. oryzae and also results in an increased burst of reactive oxygen species after flg22 and chitin treatments. In addition, the expression levels of WRKY45, NPR1 and PR5 are increased in OsDjA6 RNAi plants, indicating that OsDjA6 may mediate resistance by affecting the salicylic acid pathway. Finally, we found that OsDjA6 interacts directly with the E3 ligase OsZFP1 in vitro and in vivo. These results suggest that the DnaJ protein OsDjA6 negatively regulates rice innate immunity, probably via the ubiquitination proteasome degradation pathway.
