TMEM37 and infection: However, B. subtilis activated later a high expression of PR1 and PR4 genes, indicating the prominent role of SA-dependent immune response in ISR against Pst DC3000, as also observed with B. cereus and P. fluorescens SS101 [14,16,25]; B. subtilis PTA-271 also increased the amounts of SA and JA after Pst DC3000 infection, suggesting that this beneficial bacterium can also modulate SA-JA crosstalk by prioritizing SA-dependent immune response after Pst DC3000 infection, as observed with P. fluorescens SS101 (van de Mortel et al., 2012).
