摘要
A cDNA encoding a 70 kDa heat shock 'cognate' protein (hsc70) was isolated from Arabidopsis thaliana by using a rat hsc70 cDNA as probe. Sequence analysis demonstrated the conservation of functional domains and important amino acid residues among hsc70s in plants and animals. The expression of this gene was stress-inducible, and was found at a substantial level during normal growth in root, stem, leaf and flower tissues, but not in siliques. Multiple copies of this gene exist in the Arabidopsis genome.
