Fig. 2From: Switchgrass SBP-box transcription factors PvSPL1 and 2 function redundantly to initiate side tillers and affect biomass yield of energy cropExpression patterns of PvSPLs in wild-type switchgrass plants. a–c Expression patterns of PvSPLs in wild-type switchgrass plants were revealed by qRT-PCR. Switchgrass Ubq2 was used as the reference for normalization. d Expression patterns of mature miR156 in wild-type switchgrass plants were detected and quantified by a highly sensitive quantitative real-time PCR method. miRNA168 was used as the reference for normalization. Values are mean ± SE (n = 3)Back to article page
