Abstract: A pair of degenerate primers was designed based on the conserved sequences of the actin(ACT)genes from other plants. Total RNA was extracted from the roots of Elytrigia elongata to obtain an ACT gene fragment by reverse transcription polymerase chain reaction(RT-PCR). Results showed that the length of EeACT gene fragment was 598 bp encoding a 198 amino acids. The deduced amino acid sequence of EeACT shared over 90% amino acid homology compared with other plants ACT. No significant differences in expression level of EeACT were found between shoots and roots among low temperature, salt and drought treatments for 12 h, indicating that expression of EeACT is stable.

Key words: Elytrigia elongata, Actin gene, RT-PCR, Homo-cloning
