TL;DR: It is shown that MUM4 encodes a putative NDP-l-rhamnose synthase, an enzyme required for the synthesis of the pectin rhamnogalacturonan I, the major component of Arabidopsis mucilage, and the reduced cytoplasmic rearrangement observed in the absence of a key enzyme in pECTin biosynthesis in mum4 mutants establishes a causal link between mucilage production and cellular morphogenesis.

TL;DR: It is proposed that MUM2 is involved in modifying mucilage to allow it to expand upon hydration, establishing a link between the galactosyl side-chain structure of pectin and its physical properties.

TL;DR: Global expression datasets that can be used for identification of new gene candidates for seed coat development were generated and provide a comprehensive expression profile for developing seed coats in Arabidopsis, and should provide a useful resource and reference for other seed systems.

TL;DR: Down-regulation of KNat6 expression by RNA interference was associated with an increased total number of lateral roots, indicating a role for KNAT6 in modulating lateral root formation.

TL;DR: Flying saucer1 (fly1), a novel Arabidopsis thaliana seed coat mutant, is characterized, which displays primary wall detachment, reduced mucilage extrusion, and increased mucilage adherence and it is proposed that FLY1 regulates the DM of pectin in mucilage, potentially by recycling pECTin methylesterase enzymes in the endomembrane system of seed coat epidermal cells.
