Most plant species studied to date are recognised to constitutively express paucimannosidic N-glycoproteins. The paucimannosidic N-glycoproteins are abundantly expressed in the vacuoles of plants such as the legume seeds of Lotus japonicus, the rice seeds and leaves of Oryza sativa. Literature has provided evidence for plant-specific paucimannosidic glycan structures modified with Xyl and Fuc. Such structures are found across the broad Streptophyta (land plants) and Chlorophyta (green algae) clade and in diatoms such as Phaeodactylum tricornutum. Less reported bixylosylated paucimannosidic glycans have also been documented.
