ICE RECRYSTALLISATION INHIBITION PROTEIN OR ANTIFREEZE PROTEINS FROM DESCHAMPSIA, LOLIUM AND FESTUCA SPECIES OF GRASS

摘要

The present invention relates to nucleic acids or nucleic acid fragmentsencoding amino acid sequences for polypeptides involved in tolerance tofreezing and/or low temperature stress in plants. More particularly, thepresent invention relates to nucleic acids or nucleic acid fragments encodingamino acid sequences for ice recrystallisation inhibition proteins (IRIPs) inplants, and the use thereof for the modification of plant response to freezingand/or low temperature stress. Even more particularly, the present inventionrelates to polypeptides involved in tolerance to freezing and/or lowtemperature stress in Deschampsia and Lolium species.
