Figure 7.

Induction of the PRLIP1 gene in signaling mutants of Arabidopsis (Col-0) in response to infection with the avirulent bacterial pathogen, Pst DC3000 avrRpt2. Leaves of 4-week-old plants were injected with the bacterial cell suspension, and plant material was harvested 0, 4, or 12 h later as indicated above the figure (hpi, hours postinoculation). RNA was extracted from the wild-type, transgenic, and mutant lines (indicated on the right of the figure), and the blots were hybridized with PRLIP1- or PR1-specific probes (indicated on the top line).
