N2 - The developmental transition from flowers to the mature diaspores (seeds or fruits) depends on cell growth and differentiation (Balanza et al., 2016; Finch-Savage and Leubner-Metzger, 2006). The plant cell wall is a dynamic nanoscale network for which the classical model and role of xyloglucan-cellulose tethers in wall structure and cell growth was challenged by recent results from genetics, biomechanics and advanced imaging (Cosgrove, 2018; Moulia, 2013; Zhang et al., 2021a). Xyloglucan (XyG), the predominant hemicellulose, is composed of a a-1,4-glucan backbone that is consecutively substituted with a-1,6-linked xylosyl residues (Frankova and Fry, 2013; Pauly and Keegstra, 2016). Di Marzo et al. (2021) demonstrated that the MADS-box transcription factor SEEDSTICK (STK) specifically controls seed and fruit biology by a-xylosidase (aXYL) mediated XyG-remodelling.
