Abstract:
Objective: To clone and screen the stable internal reference genes from Dipsacus asper for qRT-PCR analysis correction, so as to provide a preliminary basis for future research on expression analysis and regulation mechanism of D. asper functional genes. Methods: The internal reference genes of Actin, Tubulin and GAPDH gene families were screened and cloned from D. asper transcriptome database. The D. asper plants from different origins, different tissues and different developmental stages were used to obtain expression information of each gene by qRT-PCR. The expression stability of each gene was analyzed by geNorm, NormFinder, BestKeeper, Delta CT and RefFinder, and the best genes were synthetically evaluated and screened. Results: Ten core fragments for candidate internal reference genes were cloned, belonging to three gene families: Actin, Tubulin and GAPDH, with high homology among them. The results of stability analysis showed that the expression of DaACT103 was stable and relatively high in different regions and tissues, while the expression of DaTUB5 was stable and relatively low in different developmental stages. Conclusion:s DaACT103 and DaTUB5 are suitable as the internal reference genes for D. asper. DaACT103 is used as the internal reference gene with high abundances and DaACT105 is used as the internal reference gene with low abundances.
