Rhododendron molle G. Don, a member of the family of Rhododendron, possesses high ornamental and medicinal value. As a species specific to Dabie Mountains, its distribution was scattered. The estimation of expression stability of internal reference genes was vital for molecular biological and genetic research. In this study, expression pattern of candidate genes RmRPL3-1, RmNAC-1, RmCOX1-4, RmRmPDS-1, RmUBQ-6, and RmL10-4 were analyzed in different tissues of R. molle by real-time quantitative RT-PCR, including root, stem, leaf, and flower. According to GeNorm, NormFinder, and Best-keepersoftwares, the most stable internal reference in different tissues of R. molle was the combination of RmCOX1-4 and RmUBQ-6. The most stable internal reference genes selected in this study will provide a basis for the following gene expression study in R. molle.
