Abstract 

We isolated a cDNA clone, CaRAV1, which exhibited significant similarity to those of Arabidopsis RAV proteins containing AP2/ERF and B3-like DNA-binding domains. CaRAV1 expression was rapidly and specifically induced in both host and non-host resistant responses against bacterial pathogens in the chili pepper plant. CaRAV1 also strongly increased following salicylic acid and ethephon treatments, whereas methyl-jasmonate only had mild effects. Furthermore, CaRAV1 transcript levels were also investigated in response to ABA and abiotic stress. No significant CaRAV1 expression was evident following ABA, mannitol, or cold treatments. These observations collectively provide initial evidence that the pepper RAV transcription factor homolog may function in plant defense responses.
