CC -!- FUNCTION: May cause loosening and extension of plant cell walls by
CC disrupting non-covalent bonding between cellulose microfibrils and
CC matrix glucans. No enzymatic activity has been found. May be required
CC for rapid internodal elongation in deepwater rice during submergence
CC (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted, cell wall {ECO:0000250}. Membrane
CC {ECO:0000250}; Peripheral membrane protein {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Expressed in lateral root primordia, adventitious
CC root primordia, coleoptiles, shoot apex, leaf primordia, panicles and
CC flowers. {ECO:0000269|PubMed:16267395, ECO:0000269|PubMed:9338967,
CC ECO:0000269|PubMed:9807819}.
CC -!- DEVELOPMENTAL STAGE: Expressed in the apical region (growing zone) of
CC the root hair. Expressed in the growing region of leaves. Expressed in
CC developing seeds. {ECO:0000269|PubMed:11030545,
CC ECO:0000269|PubMed:12428004, ECO:0000269|PubMed:9338967}.
CC -!- INDUCTION: By gibberellin (GA3), submergence and wounding.
CC {ECO:0000269|PubMed:11030545, ECO:0000269|PubMed:12428004,
CC ECO:0000269|PubMed:9338967}.
CC -!- SIMILARITY: Belongs to the expansin family. Expansin A subfamily.
