Patent ID: 8629324

Claim:
An isolated polypeptide having expansin activity, selected from the group consisting of: (a) a polypeptide comprising an amino acid sequence having at least 95% sequence identity to amino acids 18 to 268 of SEQ ID NO: 2; (b) a polypeptide encoded by a polynucleotide that hybridizes under at least very high stringency conditions with (i) nucleotides 52 to 804 of SEQ ID NO: 1, (ii) a genomic DNA sequence comprising nucleotides 52 to 804 of SEQ ID NO: 1, or (iii) a full-length complement of (i) or (ii), wherein very high stringency conditions are defined as prehybridization and hybridization at 42° C. in 5×SSPE, 0.3% SDS, 200 μg/ml sheared and denatured salmon sperm DNA, and 50% formamide and washing three times each for 15 minutes using 2×SSC, 0.2% SDS at 70° C.; and (c) a polypeptide encoded by a polynucleotide comprising a nucleotide sequence having at least 99% sequence identity to nucleotides 52 to 804 of SEQ ID NO: 1.
