[Method] Using /3-actin as the reference gene, the rela- tive transcription levels of DpXTH1 and DpXTH2 genes in roots, stems, leaves and petals of dahlia were analyzed by real-time RT-PCR. [Result] The DpXTH1 and DpXTH2 were not expressed in the roots, but expressed abundantly in the petals of dahlia. There were little expressions in the stems and leaves of dahlia. [Conclusion] The DpXTH1 and DpXTH2 were petal-specific genes and closely related to the growth and development of petals in dahlia.展开更多
