As shown in Fig. 4C, D, PR1 transcript and SA levels in DEX-treated and infected pDEX::ALD1 plants were significantly higher at 9 h when compared with the WT and ald1. By 48 h post-infection of DEX-treated plants, pDEX::ALD1 #6 showed no differences in SA levels compared with other genotypes (Fig. 4E). Here, TMEM37 is linked to infection.
