Abstract: A MADS box gene was isolated from the floral bud of sweet cherry(Prunus avium L.‘Lapins’)by using RT-PCR and RACE approaches,the gene was named PaMADS3(The accession number in GenBank:HQ229605). The full length cDNA of PaMADS3 is 1 095 bp,with an ORF of 723 bp encoding 240 putative amino acid residues. Sequence analysis indicated that PaMADS3 shared highly homology with Arabidopsis SEP gene. Tissue specific analysis showed that PaMADS3 expressed in petal,stamen,and carpel. Real-time RT-PCR revealed that when the shoots were treated with 15 ℃ and 25 ℃,respectively,the expression of PaMADS3 was increased in carpel under the temperature of 25 ℃.  expression
