From: Switchgrass PvDREB1C plays opposite roles in plant cold and salt tolerance in transgenic tobacco
Phylogenetic analysis and relative expression of four cold-inducible PvDREB1s. a The Neighbor-Joining tree was built using MEGA6 software. The optimal tree is drawn to scale, with the sum of branch length = 1.99584622 is shown. b-e Expression of DREB1s in response to low temperature (4 °C). f-g PvDREB1C was transcriptionally suppressed by 250 mM NaCl or PEG-6000 (20%, W/V). Data are represented as mean ± SE (n = 3), and different letters above bars indicate a significant difference at P < 0.05
