Fig. 5From: Evaluation of duplicated reference genes for quantitative real-time PCR analysis in genome unknown hexaploid oat (Avena sativa L.)Relative expression level of various genes in different sample sets using the most and the least stable reference genes for normalization. a, b Relative expression levels of AsPKP1 (a) and AsAGPL2 (b) in developing seeds. EP+EF1A represents the most stable RG set and GAPDH1 is the least stable RG. Error bars indicate SD of three replicates. The B, C, D, E, G, I and J refer to developing stages of oat seeds [7]. c, d Relative expression levels of AsPKP1 (c) and AsAGPL2 (d) in developing endosperms. EIF4A+HNR represents the most stable RG set and GAPDH1 is the least stable RG. Error bars indicate SD of three replicates. The B, C, D, E, G, I and J refer to developing stages of oat seeds [7]. e, f Relative expression levels of AsSGT1 (e) and AsSCL14 (f) in shoots and roots of seedlings at two-leaf and three-leaf stage. UBC21+HNR represents the most stable RG set and 18S is the least stable RG. Error bars indicate SD of three replicatesBack to article page
