Effects of PvSPL2SRDX overexpression on lignin accumulation. a AcBr lignin content of transgenic switchgrass plants. b Thioacidolysis yield of transgenic switchgrass plants. The transgenic and control plants were harvested after 4-month growth in the greenhouse. CWR cell wall residue. c Transcript abundance of monolignol genes in transgenic switchgrass plants. Values are mean ± SE (n = 3). d SBP core binding sites located in the promoter sequences of the related monolignol genes. ►, GTAC
