Summary, etc. PR-1a is a salicylic acid-inducible defense gene of tobacco (Nicotiana tabacum). One-hybrid screens identified a novel tobacco WRKY transcription factor (NtWRKY12)with specific binding sites in the PR-1a promoter at positions 2564 (box WK1)and 2859 (box WK2). NtWRKY12 belongs to the class of transcription factors in which the WRKY sequence is followed by a GKK rather than a GQK sequence. The binding sequence of NtWRKY12 (WK box TTTTCCAC)deviated significantly from the consensus sequence (W box TTGAC[C/T]) shown to be recognized by WRKY factors with the GQK sequence. Mutation of the GKK sequence in NtWRKY12 into GQK or GEK abolished binding to the WK box. The WK1 box is in close proximity to binding sites in the PR-1a promoter for transcription factors TGA1a (as-1 box)and Myb1 (MBSII box). Expression tudies with PR-1a promoterTb-glucuronidase (GUS)genes in stably and transiently transformed tobacco indicated that NtWRKY12 and TGA1a act synergistically in PR-1a expression induced by salicylic acid and bacterial elicitors. Cotransfection of Arabidopsis thaliana protoplasts with 35STNtWRKY12 and PR-1aTGUS promoter fusions showed that overexpression of NtWRKY12 resulted in a strong increase in GUS expression, which required functional WK boxes in the PR-1a promoter.
