TI  - CaWRKY2, a chili pepper transcription factor, is rapidly induced by incompatible 
      plant pathogens.

AB  - WRKY family proteins are a class of plant-specific transcription factors involved 
      in stress response signaling pathways. In this study a gene encoding a putative 
      WRKY protein was isolated from a pepper EST database 
      (http://genepool.kribb.re.kr). The cDNA, named Capsicum annuum WRKY2 (CaWRKY2), 
      encodes a putative polypeptide of 548 amino acids, containing two WRKY domains 
      with zinc finger motifs and two potential nuclear localization signals. Northern 
      blot analyses showed that CaWRKY2 mRNA was preferentially induced during 
      incompatible interactions of pepper plants with PMMoV, Pseudomonas syringae pv. 
      syringae 61, and Xanthomonas axonopodis pv. vesicatoria race 3. Furthermore, 
      CaWRKY2 transcripts were strongly induced by wounding and ethephon treatment, 
      whereas only moderate expression was detected following treatment with salicylic 
      acid and jasmonic acid. CaWRKY2 was translocated to the nucleus when a 
      CaWRKY2-smGFP fusion construct was expressed in onion epidermal cells. CaWRKY2 
      also had transcriptional activation activity in yeast. Taken together our data 
      suggest that CaWRKY2 is a pathogen-inducible transcription factor that may have a 
      role in early defense responses to biotic and abiotic stresses.
