Abstract

A pair of degenerate primers was designed based on a conserved domain of GA 20-oxidase reported in other plants. The full-length (1179 bp) carnation (Dianthus caryophyllus L. cv. Master) GA 20-oxidase cDNA (named Dc20ox) was cloned by reverse transcriptase-polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends (RACE). BLAST analysis revealed that the deduced amino acid sequence had high homology (66–75%) with the GA 20-oxidase sequences from other plants. An RNAi vector (pART400) was constructed from a 400 bp fragment representing a highly conserved region of GA 20-oxidase.
