Genomic distribution and context dependent functionality of novel WRKY transcription factor binding sites.

Background: The WT-boxes NGACTTTN are novel microbe-associated molecular pattern (MAMP)-responsive cis-regulatory sequences. Many of them are uncommon WRKY transcription factor (TF) binding sites.

Results: To understand their functional relevance, a genomic distribution analysis of the 16 possible WT-boxes and a functional analysis of a WT-box rich promoter was done.
