ABSTRACT
The open reading frame of 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate reductase (HDR) was cloned from Phlegmarirus carinatus by RT-PCR method and the sequence was analyzed by bioinformatics tools. After searching the transcriptome dataset of P. carinatus, one unique sequence encoding 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate reductase was discovered. The primers were designed according to the cDNA sequence of 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate reductase from the dataset. And then, the open reading frame (ORF) of 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate reductase, named as PcHDR1 (GenBank Accession number:JQ957845), was cloned by RT-PCR strategy with the template of mixed RNA extracted from roots, stem and leaf of P. carinatus. The bioinformatic analysis of this gene and its corresponding protein was performed. The ORF of PcHDR1 consisted of 1 437 base pairs (bp), encoding one polypeptide with 478 amino acids. The sequence comparison showed that PcHDR1 is closest with GbHDR (Ginkgo biloba),and the sequence homology was up to 78%. Bioinformatics prediction and analysis indicated that PcHDR1 protein contained a conserved domain of LytB, without transmembrane region and signal peptides. This study cloned and analyzed 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate reductase from P. carinatus. The result will provide a foundation for exploring the function of PcHDR1 involved in terpene biosynthesis in P. carinatus plants.
