Fig. 2From: A positive feedback regulatory loop, SA-AtNAP-SAG202/SARD1-ICS1-SA, in SA biosynthesis involved in leaf senescence but not defense responseqPCR analyses of gene expression upon chemical induction of AtNAP or SAG202. (a-e) The transcript levels of AtNAP, SAG202/SARD1, CBP60g, ICS1 and ICS2 in the AtNAP inducible (AtNAPin) and control lines at 0 h, 3 h, 6 h and 24 h after DEX treatment. (f-h) The transcript levels of SAG202, ICS1 and ICS2 in the SAG202in and control lines at 0 h, 3 h, 6 h and 24 h after DEX treatment. Relative expression levels were calculated and normalized with respect to Actin 2 (ACT2) transcripts. Error bars indicate SD of three biological repeats. *P < 0.05 using Student’s t-testBack to article page
