RT   "Germin isoforms are discrete temporal markers of wheat development.
RT   Pseudogermin is a uniquely thermostable water-soluble oligomeric protein in
RT   ungerminated embryos and like germin in germinated embryos, it is
RT   incorporated into cell walls.";
RL   Eur. J. Biochem. 209:961-969(1992).
CC   -!- FUNCTION: May subsume the role of germin at the low water potentials
CC       during embryogenesis.
CC   -!- SUBUNIT: Homotetramer.
CC   -!- SUBCELLULAR LOCATION: Secreted, extracellular space, apoplast.
CC       Secreted, cell wall. Note=Component of the walls of the mature,
CC       ungerminated embryos.
CC   -!- DEVELOPMENTAL STAGE: Accumulates maximally between 20-25-days
CC       postanthesis, then declines appreciably in amount by 30-days
CC       postanthesis, in soluble extracts of immature embryos.
CC   -!- SIMILARITY: Belongs to the germin family. {ECO:0000305}.
