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

摘要

The present invention relates to nucleic acids or nucleic acid fragmente cncoding amino acid scqucnces for polypep-tides involved in tolerancc to frcc/ing and'or low temjx;raturc sircss in plants. More particularly, the present invention rciatcs to nucleic acids or nucleic acid fragtncnts er.coJing amino acid sciiuences t'or ice recrystallisation inhibition proteins (IRBPs) in plante, and the use theteof for thc modification of plani responsc io freczing and/or low temperature stress. Even more parttcularly, flj^ present invention relates to polypcptides involved in tolcrance to freezing and/or low temperature stress in Dcschamprit and Lolium species.
