Abstract: A MADS-box gene named DkMADS1 was cloned from Yangfeng persimmon flowers (GenBank
accession No. DQ412058). The sequence of complete DkMADS1 cDNA gene is 1 193 bp, with an ORF en
coding 249 amino acids. The deduced protein contained conservative MADS domain and semi-conservative K
domain. It shared highly homology to other MADS-box proteins from different species. RT-PCR analysis
showed that DkMADS1 gene was exp ressed in sepal, petal, ovary of Yangfeng persimmon and stamen of Zenji
maru persimmon.
