What is A novel regulatory element involved in rapid activation of parsley ELI7 gene family members by fungal elicitor or pathogen infection about?

## Abstract In parsley (__Petroselinum crispum__), members of the __ELI7__ gene family were rapidly transcriptionally activated following treatment with an elicitor derived from the phytopathogen __Phytophthora sojae__. Several cDNA and genomic __ELI7__ clones were isolated. The deduced amino acid sequences revealed close similarity to fatty acid desaturases/hydroxylases, however, the precise functions are still unknown. Analysis of the promoters of two strongly elicitor‐induced family members, __ELI7.1__ and __ELI7.2__, allowed us to functionally pinpoint a novel, independently acting regulatory region (S box), the only major sequence similarity between the two gene promoters. __In situ__ RNA/RNA hybridization using an __ELI7.1__ gene‐specific probe demonstrated that expression of this gene is rapidly and locally induced around infection sites __in planta__ as well.
