Abstract: Ethylene and extracellular hydrogen peroxide co-regulate formation of a sterol-enriched plasma membrane domain in trans-differentiating epidermal transfer cells that functions to co-ordinate construction of their wall labyrinth.

“…In the case of UWL formation (Fig. 7), our previous studies suggested that the PM-located apo H 2 O 2 signal acted by inducing a microtubule/actin-independent polarized vesicle docking system, embedded in sterol-enriched domains, located along the entire outer periclinal region of the ETC PM (Zhang et al , 2019). In contrast, the concurrent VfrbohB/PAO/Prx original wall-generated apo H 2 O 2 signal, residing in the cell wall matrix, played no role in UWL construction.…”

“…This was shown to be guided by an extensive transmembrane polymeric platform formed by Casparian Strip domain proteins (CASPS) (Lee et al , 2013). In contrast, for trans -differentiating ETCs, apo H 2 O 2 would appear to direct spatial organization of lipid-enriched domains in the outer periclinal region of the PM (Zhang et al , 2019).…”

“…The latter is mediated by apo H 2 O 2 upregulating a cytoskeleton‐independent mechanism of docking/fusion of vesicles carrying cargoes of phytosterols while blocking their endocytosis in the outer periclinal region of the ETC plasma membrane (Fig. 4c; Zhang et al ., 2019). In line with these roles, catalytic activities of plasma membrane‐localized Prxs are evenly spread across the plasma membrane lining the outer periclinal wall during UWL formation.…”
