In order to analyze the expression of genes involved in steroidal saponin biosynthesis pathway in Polygonatum cyrtonema tubers, it is very important to select internal reference genes that are stably expressed at different development stages and in response to abiotic stress. According to the previously established P. cyrtonema transcriptome database and reported internal reference genes in plant, this study systematically analyzed eight candidate internal reference genes including histone H2 A, glyceraldehyde-3-phosphate dehydrogenase, ACTIN, β-tubulin, ubiquitin-conjugating enzyme-E2-10, elongation factor 1-alpha isoform, 18 S rRNA and α-tubulin 4 for expression stability in P. cyrtonema tubers at different development stages and in response to methyl jasmonate(MeJA) stress by using Real time fluorescence quantitative PCR(qPCR). Based on the statistical analysis of qPCR results by using GeNorm, NormFinder and BestKeeper softwares, the expression of ubiquitin-conjugating enzyme-E2-10 and elongation factor 1-alpha isoform are the most stable in P. cyrtonema tubes at different development stages and in response to MeJA stress. The two internal reference genes were further validated by analyzing the expression of 4 genes involved in steroidal saponin biosynthesis pathways. In conclusion, ubiquitin-conjugating enzyme-E2-10 and elongation factor 1-alpha isoform can be used as the most appropriate internal reference genes for qPCR analysis in P. cyrtonema. This study also provide ...
