TMEM37 and infection: In rice, infection with Pseudomonas syringae or treatment with BTH can induce SAR-like response against the rice blast fungus and is associated with the transcriptional activation of PR genes (Smith and Métraux, 1991; Schweizer et al., 1999) However, compared to Arabidopsis, rice has relatively higher endogenous levels of SA, which do not increase upon pathogen infection (Silverman et al., 1995; Chen et al., 1997).
