      abstract     = {All cells of terrestrial plants are fortified by walls
                      composed of crystalline cellulose microfibrils and a variety
                      of matrix polymers. Xylans are the second most abundant type
                      of polysaccharides on Earth. Previous studies of Arabidopsis
                      (Arabidopsis thaliana) irregular xylem (irx) mutants, with
                      collapsed xylem vessels and dwarfed stature, highlighted the
                      importance of this cell wall component and revealed multiple
                      players required for its synthesis. Nevertheless, xylan
                      elongation and substitution are complex processes that
                      remain poorly understood. Recently, seed coat epidermal
                      cells were shown to provide an excellent system for
                      deciphering hemicellulose production. Using a coexpression
                      and sequence-based strategy, we predicted several
                      MUCILAGE-RELATED (MUCI) genes that encode
                      glycosyltransferases (GTs) involved in the production of
                      xylan. We now show that MUCI21, a member of an
                      uncharacterized clade of the GT61 family, and IRX14 (GT43
                      protein) are essential for the synthesis of highly branched
                      xylan in seed coat epidermal cells. Our results reveal that
                      xylan is the most abundant xylose-rich component in
                      Arabidopsis seed mucilage and is required to maintain its
                      architecture. Characterization of muci21 and irx14 single
                      and double mutants indicates that MUCI21 is a
                      Golgi-localized protein that likely facilitates the addition
                      of xylose residues directly to the xylan backbone. These
                      unique branches seem to be necessary for pectin attachment
                      to the seed surface, while the xylan backbone maintains
                      cellulose distribution. Evaluation of muci21 and irx14
                      alongside mutants that disrupt other wall components
                      suggests that mucilage adherence is maintained by complex
                      interactions between several polymers: cellulose, xylans,
                      pectins, and glycoproteins.},
