Abstract: In this study a ripening related ethylene receptor etr2 gene in strawberry fruits was cloned for the following-up research on gene funct ion and improving variet ies of strawberry through transgenic technology. A pair of primers were designed and synthesized based on the sequence reported of Chandler -Etr2. Using genome DNA extracted from Chinyoda strawberry mature fruits as template the specific PCR product of etr2 was obtained, then it was ligated to pGEM-T easy vector and sequenced. The sequencing data showed that the PCR product was 1 049 bp encoding 349 predicted amino acid residues. Comparison with the cDNA sequence from Chandler - etr2 indicated the homlogy was 99%, and amino acid identities were 98%.
