Fig. 2: Characterization of LcBZR1 and LcBZR2.

a Amino acid sequence alignment of LcBZR1/2 with homologs from banana (Ma, Musa acuminate L.), rice (Os, Oryza sativa L.) and Arabidopsis (At, Arabidopsis thaliana). b Phylogenetic analysis of LcBZR1/2 with homologs from banana (Ma, Musa acuminate L.), rice (Os, Oryza sativa L.), tomato (Sl, Solanum lycopersicum) and Arabidopsis (At, Arabidopsis thaliana). c Subcellular localization of LcBZR1/2 in tobacco leaves. LcBZR1/2 fused to GFP and the positive control pEAQ-GFP were transformed into tobacco leaves. After 48 h of incubation, GFP signals were observed under a confocal laser scanning microscope. The nucleus is indicated by 4,6-diamidino-2-phenylindole (DAPI) staining. Merged images indicate the colocalization of DAPI and GFP signals. Scale bars indicate 25 µm. d Transcriptional repression ability of LcBZR1/2 in tobacco leaves. The transcriptional activity of LcBZR1/2 was tested by the dal-luciferase reporter assay by detecting the ratio of LUC to REN. The SE was calculated from six replicates. **Significant differences in values according to Student’s t test (P < 0.01).
