We had previously shown that several transcription factors of the ethylene (ET) response factor (ERF) family were induced with different but overlapping kinetics following challenge of Arabidopsis (Arabidopsis thaliana) with Pseudomonas syringae pv tomato DC3000 (avrRpt2). One of these genes, a transcriptional activator, AtERF14, was induced at the same time as ERF-target genes (ChiB, basic chi...

Plants are continually exposed to potential pathogens and herbivores and have evolved defenses to counter such opportunistic invasions, including both physical (i.e. waxy cuticles, cell walls) and biochemical (i.e. defense compounds) barriers (for review, see Grennan, 2006). A key component to mounting an effective response, which may involve a change in gene expression, is an efficient signali...

It is well established that salicylic acid (SA) plays a critical role in the transcriptional reprograming that occurs during the plant defense response against biotic and abiotic stress. In the course of the defense response, the transcription of different sets of defense genes is controlled in a spatio-temporal manner via SA-mediated mechanisms. Interestingly, different lines of evidence indic...
