摘要: CELLULOSE SYNTHASE5 (CESA5) synthesizes cellulose necessary for seed mucilage adherence to coat epidermal cells of Arabidopsis (Arabidopsis thaliana). The involvement additional CESA proteins in this process and details concerning the manner which is deposited pocket are unknown. Here, we show that both CESA3 CESA10 highly expressed cell type at time synthesis localize plasma membrane adjacent pocket. isoxaben resistant1-1 resistant1-2 mutants affecting defects consistent with altered biosynthesis. can interact CESA5 vitro, green fluorescent protein-tagged CESA5, CESA3, move a linear, unidirectional fashion around cytoplasmic column cell, parallel surface seed, pattern similar cortical microtubules. Consistent movement, cytological evidence suggests coiled columella unwinds during extrusion form linear ray. Mutations affect speed adherence. These findings imply fibrils synthesized an ordered helical array columella, providing distinct structure important
