MUC21_ARATH | developmental stage | Expressed in the seed coat at the linear cotyledon and mature green stages, when mucilage synthesis occurs. |
MUC21_ARATH | function | Glycosyletransferase required for the proper composition and structural properties of released seed coat mucilage (PubMed:11706181, PubMed:26482889, PubMed:26979331). Required for the production of highly branched xylan polymers in seed coat mucilage (PubMed:26482889). Facilitates the addition of xylose residues directly to the xylan backbone (PubMed:26482889, PubMed:26979331). Xylan with xylose side chains seems to be necessary for pectin attachment to the seed surface (PubMed:26482889, PubMed:26979331). Essential for xylan synthesis in seed coat epidermal (SCE) cells (PubMed:26482889). |
MUC21_ARATH | similarity | Belongs to the glycosyltransferase 61 family. |
