Identification of a conserved GCN-like cis-element in the Triticeae ASN1 promoters. A Genome position and browser view of the HvASN1 locus on chromosome 5 in Hordeum vulgare ssp. vulgare L. Exons of HvASN1 are represented as gray boxes, and introns as lines. The arrow indicates the direction of transcription. B Pairwise alignment of ASN1 promoter sequences from different Triticeae species, using phylogenomic analysis with the mVISTA tool. Graphical output shows base pair % identity in a sliding window of 100 bp with a 70% identity threshold. Gray areas indicate a conserved block. C Sequence alignment of the conserved block identified in B in the Triticeae ASN1 promoters. The GCN‐like box is indicated. Aet, Aegilops tauschii; Ta, Triticum aestivum; Tu, Triticum urartu; Hv, Hordeum vulgare
