Abstract: Interactions between cell wall polymers are critical for establishing cell wall integrity and cell-cell adhesion. Here, we exploit the Arabidopsis (Arabidopsis thaliana) seed coat mucilage system to examine cell wall polymer interactions. On hydration, seeds release an adherent mucilage layer strongly attached to the seed in addition to a nonadherent layer that can be removed by gentle agitation. Rhamnogalacturonan I (RG I) is the primary component of adherent mucilage, with homogalacturonan, cellulose, and xy… Show more

“…Moreover, SOS5/FLA4 (At3g46550), a fasciclinlike GPI-anchored AGP, was recently shown to be involved in the formation of either a pectin or a pectinhemicellulose network in seed mucilage (Griffiths et al, 2014). Although the distribution of AGPs and pectins are not identical in primexine, AGPs and/or pectins and possibly xylan (Li et al, 2017) might function as a scaffold for other wall components and could potentially be cross-linked to each other.…”
