TMEM37 and infection: Namely, PstDC3000 infection following 3OC8-HSL pretreatment led to the following: 1) enhanced accumulation of free SA in the leaves; 2) strong and rapid expression induction of the SA biosynthesis gene ICS1 along with CBP60g and SARD1, two transcription factor genes that regulate ICS1; and 3) potentiated expression of PR1 and PR5, two genes typically regulated by the SA pathway upon pathogen infection.
