CC   -!- FUNCTION: May play a role in nitrogen storage.
CC   -!- SUBUNIT: Monomer.
CC   -!- TISSUE SPECIFICITY: Bark.
CC   -!- INDUCTION: By photoperiod. Short days stimulate accumulation, while
CC       long days inhibit.
CC   -!- SIMILARITY: To wound-inducible poplar endochitinases. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=CAA49669.1; Type=Erroneous initiation; Evidence={ECO:0000305};
