Abstract: In this work,a full-length cDNA sequence of MDH gene was obtained from petals of tree peony(Paeonia suffruticosa L.cv.Zhao Fen)using RT-PCR and RACE,named PsMDH(GenBank accession No.HQ449567).The full length of PsMDH cDNA is 1 283 bp,containing a 5′-untranslated region(5′-UTR) of 80 bp,a 3′-UTR of 203 bp,and an opening reading frame(ORF) of 999 bp encoding a 332 predicted amino acids.Subsequently,sequence comparison and phylogenetic analysis revealed that PsMDH shared more than 93.37% homology with Populus trichocarpa.Relative Real-time PCR analysis indicated that PsMDH showed the highest transcript abundance in carpels and the lowest levels in stamens.Construction of plant expression vector lay a foundation for variety improvement in tree peony.
