Fig. 5. Model for elicitor signal transduction leading to Str expression. The model shows the positions of CrBPF-1 in a JA-independent, and ORCAs in a JA-dependent, elicitor signal transduction pathway. Protein phosphorylation and calcium influx are required for elicitor-induced jasmonate biosynthesis, as well as for the induction of CrBPF-1, ORCA2, and ORCA3. ORCA activation additionally depends on jasmonate biosynthesis. The positions of the TATA box, the BA region, and the jasmonate- and elicitor-responsive element (JERE) within the Str promoter are indicated...

A recent report suggested that some kind of transmembrane signaling event, activating a calcium influx, occurs rapidly after ToxB contact with cells and is required for the disruption of actin filaments (Gilbert et al., 1995). However, a calcium influx is required for endocytosis of ToxB (Caspar et al., 1987), which may explain this observation.
