abstract = {Pectin is a vital component of the plant cell wall and
provides the molecular glue that maintains cell-cell
adhesion, among other functions. As the most complex wall
polysaccharide, pectin is composed of several covalently
linked domains, such as homogalacturonan (HG) and
rhamnogalacturonan I (RG I). Pectin has widespread uses in
the food industry and has emerging biomedical applications,
but its synthesis remains poorly understood. For instance,
the enzymes that catalyze RG I elongation remain unknown.
Recently, a coexpression- and sequence-based
MUCILAGE-RELATED (MUCI) reverse genetic screen uncovered
hemicellulose biosynthetic enzymes in the Arabidopsis
(Arabidopsis thaliana) seed coat. Here, we use an extension
of this strategy to identify MUCI70 as the founding member
of a glycosyltransferase family essential for the
accumulation of seed mucilage, a gelatinous wall rich in
unbranched RG I. Detailed biochemical and histological
characterization of two muci70 mutants and two
galacturonosyltransferase11 (gaut11) mutants identified
MUCI70 and GAUT11 as required for two distinct RG I domains
in seed mucilage. We demonstrate that, unlike MUCI70, GAUT11
catalyzes HG elongation in vitro and, thus, likely is
required for the synthesis of an HG region important for RG
I elongation. Analysis of a muci70 gaut11 double mutant
confirmed that MUCI70 and GAUT11 are indispensable for the
production and release of the bulk of mucilage RG I and for
shaping the surface morphology of seeds. In addition, we
uncover relationships between pectin and hemicelluloses and
show that xylan is essential for the elongation of at least
one RG I domain.},
