Fig. 7From: A positive feedback regulatory loop, SA-AtNAP-SAG202/SARD1-ICS1-SA, in SA biosynthesis involved in leaf senescence but not defense responseGrowth of P. syringae pv. Tomato DC3000 in leaves of WT, atnap, sag202, ics1, s3h null mutants and S3HOE1 transgenic plants. The number of colony-forming units (cfu) per square centimeter of leaf area was determined 0, 1, and 2 days after inoculation. Error bars indicate SD of three biological repeats. *, ** and *** indicate P < 0.05, P < 0.01 and P < 0.001, respectively. Student’s t-test was used. The s3h null mutant (resistant to the infection) and S3HOE1 transgenic plants (susceptible to the infection) (Zhang et al., 2013) were included for comparison purposeBack to article page
