The phenotype comparision and expression levels analysis of flowering-related genes in transgenic switchgrass. (a,b): Phenotypes of switchgrass overexpressing oAANAT and oHIOMT. Expression levels of APL1 (c), SL1 (d), FT1 (e), FLP3 (f), MADS14 (g), and MADS14 (h). WT: wild type; EV: lines expressing the empty vector only; OE-oAANAT: transgenic plants of oAANAT; OE-oHIOMT: transgenic plants of oHIOMT; The data show the mean ± S.E. of triplicate measurements. * and ** indicate a significant difference from that of WT at P < 0.05 and P < 0.01, respectively.
