No E and N motifs in High molecular weight glutenins Martin Müller, Bavarian State Research Center for Agriculture 31 January 2014 There seems to be a problem with the article published in SpringerPlus by Jiang et al. (SpringerPlus 2013, 2:152) Characterization of x-type high-molecular-weight glutenin promoters (x-HGP) from different genomes in Triticeae. The paper is on promoter sequences of high molecular weight glutenins of different Triticeae. The authors claim that there are E (TGTAAATC) and N (TGAGTCAT) motifs in these sequences, but actually there are no such sequence motifs in the promoters of HMW glutenin. Furthermore, the sequence depicted in figure 3 of the paper corresponding to Triticum urartu (first line of the alignment) is not matching to any of the the sequences of Triticeae found in Blast queries of genebanks.
