Our data that aba2-1 increased, but 35S::ABA2 and wild-type plants treated with ABA reduced the expression of SA-dependent PR1 gene expression under PstDC3000 infection (Figure 5B,C), indicate the similarity between endogenous and exogenous ABA in SA signaling, and support the antagonism of ABA in SA signaling in Arabidopsis. Here, TMEM37 is linked to infection.
