Fig. 5From: Selection and validation of reference genes for quantitative expression analysis of miRNAs and mRNAs in PoplarRelative expression of miR166 and PtHB4 using validated reference genes for normalization under AR regeneration. PP2A-2, UBP, bHLH, PP2A-2 + UBP and PP2A-2 + bHLH were selected for the stable reference genes, and 5.8 s and miR403 were the two least stable genes for normalization RT-qPCR analysisBack to article page
