[Cloning and expression analysis of CpPMM gene in Codonopsis pilosula].

GDP-mannose is an important precursor for the synthesis of Codonopsis pilosula polysaccharides and involved in the synthesis of sugar chains. Phosphomannomutase(PMM)catalyzes the conversion of mannose-6-phosphate(Man-6-P)to mannose-1-phosphate(Man-1-P)to synthesize GDP-mannose. In this study, specific primers were designed based on the PMM gene sequence information in transcriptome data, and the full length of the C.
