Detection of Lewis A structures in Arabidopsis accessions carrying GALT1 polymorphisms. (A) Protein sequence of GALT1 from Arabidopsis Col-0. The transmembrane domain is shown in gray, the putative galactoside-binding lectin domain in green, and the galactosyltransferase domain in yellow. Additionally, the DXD-motif in the catalytic site is highlighted in light blue and the conserved GxxYxxS as well as the adjacent DxA motif are highlighted in magenta. Underlined amino acids indicate N-glycosylation sequons. Sites depicted in bold show positions of amino acids, for which we could find variations in the 1001 genome database. (B,C) Immunoblot analysis of the indicated Arabidopsis accessions. Total protein extracts from stems and siliques, respectively, were analyzed with antibodies directed against Lewis A bearing (JIM84) and plant N-glycans carrying β1,2-xylose and core α1,3-fucose (anti-HRP).
