MOESM4 of Switchgrass SBP-box transcription factors PvSPL1 and 2 function redundantly to initiate side tillers and affect biomass yield of energy crop

Abstract

Additional file 4: Figure S2. Relationships between expression levels of the miR156-targeted PvSPL genes and tiller numbers. Twelve independent positive miR156 overexpressing transgenic switchgrass lines were generated by Agrobacterium-mediated transformation. Expression levels of PvSPL1/19, 2/18, 3/5, and 6/7 in the transgenic switchgrass plants were detected by qRT-PCR. Switchgrass Ubq2 was used as the reference for normalization
