Fig. 8From: Two β-glucuronosyltransferases involved in the biosynthesis of type II arabinogalactans function in mucilage polysaccharide matrix organization in Arabidopsis thalianaColumella and radial cell wall are severely impaired in the glcat14a-1glcat14c-1 double mutant seeds. Scanning electron microscopy of the seed coat surface of WT (a) and glcat14a-1glcat14c-1 double mutant seeds (b). Seeds were imbibed in water and visualized for alterations in the seed coat surface in WT (c) and glcat14a-1glcat14c-1 double mutant seeds (d). Quantification of columella area before water hydration (e) and after water hydration (f). *, Significant differences from wild type (Student t test, P < 0.05)Back to article page
