Cloning and sequencing of cDNA fragment of gene of wheat (Triticum aestivum. L) induced by dehydration

cDNA fragment of the gene (dehydration induced,di1) of wheat (Triticum aestivum. L) induced by 30% PEG-6000 ( 1.13 MPa) treatment was isolated with mRNA differential display technique. Northern blot analysis showed that the expression ofdi1 gene improved at 10 h reached the highest at 48 h under 30% PEG-6000 treatment. cDNA fragment ofdi1 gene has been cloned and sequenced (211 bp). DNA sequence analysis shows that there is no homologue in GenBank todi1 cDNA.
