CC -!- FUNCTION: May have a specific role in modifying the cell-wall
CC structure, specifically during seed germination, thus facilitating
CC radicle protrusion. {ECO:0000269|PubMed:10972890}.
CC -!- SUBCELLULAR LOCATION: Secreted, primary cell wall {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Specifically expressed in endosperm during seed
CC germination, at the site of radicle protrusion.
CC {ECO:0000269|PubMed:10972890}.
CC -!- INDUCTION: Under positive control of gibberellic acid.
CC {ECO:0000269|PubMed:10972890}.
CC -!- SIMILARITY: Belongs to the extensin family. {ECO:0000305}.
