Comparative analysis of the VRN-A1 , VRN-B1 and VRN-D1 copies highlighting different TE content. Accession numbers used to represent the three genes are shown on the left, with corresponding size. The three genes are drawn at the same scale. Grey (VRN-A1) and dark blue (VRN-B1 and VRN-D1) rectangles represent exons. The black box in VRN-A1 highlights position of the promoter region as described in . Purple lines highlight positions of transposable element sequences as defined by our annotation, with corresponding class and name shown below. Blue lines represent the annotation of two SINE elements that could not be found in our analysis but were described in GeneBank accession AY747604.1 . Light blue parallelograms represent conserved regions as defined by our GEvo analysis.
