Switchgrass lines overexpressing OsAT10 show alterations in cell wall-bound phenolics. a Quantitative analysis of cell wall-bound phenolics of green leaves of the wild-type (WT) (3 biological replicates) and OsAT10 overexpressing switchgrass lines, FT2 (4 biological replicates) and FT8 (4 biological replicates). b Quantitative analysis of cell wall-bound phenolics from senesced tissues of the same set of switchgrass lines. The numbers of biological replicates of senesced tissues of lines WT, FT2 and FT8 are 4, 5, and 5, respectively. No technical replicates were used. Bars indicate standard deviation, and asterisks indicate significant differences using the unpaired Student’s t-test (*P < 0.05; **P < 0.01)
