RT   protein from leaves of Guilder rose (Hydrangea macrophylla).";
RL   Protein Expr. Purif. 24:76-82(2002).
CC   -!- FUNCTION: Has antifungal activity against A.alternata, A.cucumerina,
CC       A.niger, C.gossypii, F.oxysporum, F.oxysporum subsp melonis,
CC       F.moniliforme, T.cucumeris, and V.dahliae. Has no chitinase or
CC       agglutination activities. {ECO:0000269|PubMed:11812226}.
CC   -!- INDUCTION: By ethylene. {ECO:0000269|PubMed:11812226}.
CC   -!- MASS SPECTROMETRY: Mass=30010; Method=Electrospray;
CC       Evidence={ECO:0000269|PubMed:11812226};
CC   -!- SIMILARITY: Belongs to the parathyroid hormone family. {ECO:0000305}.
CC   -!- CAUTION: 14 of the 15 residues are identical to an internal region of
CC       human parathyroid hormone. That seems quite an incredible
CC       'coincidence'. {ECO:0000305}.
