N ‐glycosylation is a common protein modification. Joining of polypeptide and carbohydrate elements into hybrid molecules provides an opportunity to fine‐tune protein properties. However, the role of N ‐glycosylation on the development of multicellular organisms remains elusive. Here we report a hypomorphic allele of KNOPF / GLUCOSIDASE 1 , which allows us to describe the effects of impaired α‐glucosidase I on post‐embryonic development of plants for the first time. This knf‐101 mutation alters cell shape but does not affect cell arrangements, except for the patterning of specialized epidermal cells, delineating the significance of N ‐glycan processing during epidermal development in Arabidopsis .
