Potential internal promoter in the DNA-B intergenic region of EuMV. Alignment of a domain of the DNA-B intergenic region of EuMV-Jal with the coat protein (CP) gene promoter of Rhynchosia golden mosaic Yucatan virus [GenBank: GQ352453]. The blocks of high sequence similarity encompassing more than eight nucleotides are "phylogenetic footprintings" (PFp; boxed). Putative cis-acting elements within the PFp (identified by roman numerals) are as follows: I) Conserved Late Element, CLE (inverted); II) salycilic acid responsive element (inverted, restricted similarity); III) A pathogen-elicitor responsive element (Box W1) overlapped with a CCAAT box; IV) conserved element with indeterminated function; V) sequence highly similar to the 3'end of the TGMV CP promoter "region C", that functions as transcriptional negative element [67]; VI) potential auxin-responsive element (ARE, at the block 3'end); VII) TATA box; VIII) canonical salycilic acid responsive element; IX) ethylene-responsive element (ERE)-like motif. The block "X" includes the first segment of the RhGMYuV CP gene. Notice the 8-nt long stretch of identical sequence between the non-coding sequence of EuMV-Jal DNA-B and the coding sequence of RhGMYuV.
