Expression analysis of switchgrass PvUbi1 (black) and PvUbi2 (gray) in a variety of switchgrass tissues using qRT-PCR. Relative quantification was performed using the standard curve method, and transcript accumulation of each gene was normalized to the quantity of an expressed switchgrass actin (PvAct) gene. Each bar represents the mean of three independent replicates with the standard errors of the noted mean.
