In Arabidopsis mutants for Hsp20 genes involved in the responses to nematode infection, the TATAbox element should be preferentially located between 12 and 21 bp upstream of the transcription start site, followed by an HSE at around −83 bp and a CCAAT box between 84 and 141 bp upstream of the transcription start site [14]. This evidence concerns the gene HSPB6 and Nematoda infectious disease.
