Interaction of GmERF113 with GmbHLH in yeast cells and planta. (A) GmERF113-II interacted with GmbHLH in yeast cells. The yeast cells were selected on SD (-Trp, -Leu) (DDO) medium and interactions were evaluated based on the ability of cells to grow on selective SD (-Trp, -Leu, -His, -Ade) (QDO) medium containing X-α-Gal (20 μg mL-1) and aureobasidin A (125 μgmL-1) for 5 days. Yeast Y2HGold cells carrying pGBKT7-P53 and pGADT7-SV40 served as positive controls, whereas co-expression of pGBKT7-lam and pGADT7-SV40 was used as a negative control (Clontech, USA). (B) BiFC assay of the interaction of GmERF113 with GmbHLH. GmERF113-YFPN and GmbHLH-YFPC were co-transfected into Arabidopsis protoplasts and observed using a confocal microscope. Bright-field, YFP fluorescence (yellow), chlorophyll autofluorescence (red), and combined images were visualized. Bars, 10 μm.
