Patent ID: 7186888

Claim:
An isolated polynucleotide selected from the group consisting of: (a) a polynucleotide encoding a polypeptide comprising the amino acid sequence of SEQ ID NO: 2; (b) a polynucleotide comprising a nucleotide sequence of positions 296–3196 of the nucleotide sequence of SEQ ID NO: 1; (c) a polynucleotide encoding a polypeptide comprising an amino acid sequence that is at least about 95% identical to the amino acid sequence of SEQ ID NO: 2, wherein expression of the of the polynucleotide is increased in response to cold-stress of a plant, and wherein the polypeptide interacts with calreticulin; and (d) a polynucleotide hybridizing under stringent conditions of 6 M urea, 0.4% SDS and 0.1×SSC with the complement of SEQ ID NO: 1, wherein expression of the polynucleotide is increased in response to cold-stress of a plant and the polynucleotide encodes a polypeptide that is at least about 95% identical to the amino acid sequence of SEQ ID NO: 2, and said polypeptide interacts with calreticulin.
