Auxin response is enhanced in zll-1 mutant embryos. Upper two lanes show overlays of DR5:GFP signal and differential interference contrast images. Images were taken at the same settings. In the bottom two lanes, the corresponding heat maps of DR5:GFP expression are shown. Rainbow gradient from blue (no expression) to red (high expression) is used. Scale bars: 15 μm, except for bent-cotyledon stage, 30 μm. Genotypes and embryo stages are indicated
