In addition to self‐dimerization, RGII has been reported as forming B‐containing complexes with plasma membrane glycosylinositol phosphorylceramides (GIPCs) in Rosa cell cultures and binding to AGP‐extensin in symbiotic infection threads via B‐dependent linkages (Reguera et al., 2010; Voxeur & Fry, 2014). Here, ATP5MK is linked to infection.
