Abstract:

A PCR-based homologous cloning strategy was used to identify an actin gene from the roots of Chinese licorice(Glycyrrhiza uralensis Fisch). Results of sequence analysis indicate that a 1137 bp cDNA with an open reading frame encoding 377 amino acids, actin ortholog, GuActin, was successfully cloned and characterized(GenBank accession No. EU190972). Thus far, GuActin is the first actin of Chinese licorice that has been identified at a molecular level. Analysis by Northern blot shows that GuActin was expressed strongly in the roots, particularly in radicles than in stems and leaves. These results suggest that GuActin may be a member of the vegetative subfamily of the actin family.
