Addtional InformationFUNCTION:May cause loosening and extension of plant cell walls by disrupting non-covalent bonding between cellulose microfibrils and matrix glucans. No enzymatic activity has been found. May be required for rapid internodal elongation in deepwater rice during submergence (By similarity).TISSUE SPECIFICITY:Expressed in adventitious root primordia, coleoptiles, shoot apex, leaf primordia, panicles and flowers.DEVELOPMENTAL STAGE:Expressed in the apical region (growing zone) of the root hair. Expressed in the basal growing zone of air-grown internode. Expressed in the growing region of leaves. Expressed in the developing seeds.INDUCTION:By gibberellin (GA3) and wounding.SIMILARITY:Belongs to the expansin family. Expansin A subfamily.SIMILARITY:Contains 1 expansin-like CBD domain.SIMILARITY:Contains 1 expansin-like EG45 domain.
