The regulation of the cytosolic ACCase (ACCase) gene promoter from Phaseolus vulgaris (Pv) was studied in transgenic Arabidopsis plants using a ß-glucuronidase (GUS) reporter gene fusion (PvACCase::GUS). Under normal growth conditions, GUS was expressed in hydathodes, stipules, trichome bases, flower, pollen, and embryos. In roots, the expression was observed in the tip, the elongation zone, the hypocotyl/root transition zone, and lateral root primordia. The PvACCase promoter was induced by wounding, Pseudomonas syringae infection, H2O2, jasmonic acid (JA), ethylene, or auxin treatment. Analysis of PvACCase::GUS expression in JA and ethylene mutants (coi1-1, etr1-1, coi1-1/etr1-1) suggests that neither JA nor ethylene perception participates in the activation of this gene in response to wounding although each of these independent signaling pathways is sufficient for pathogen or H2O2-induced PvACCase gene expression. We propose a model involving different pathways of PvACCase gene activation in response to stress.
