Fig. 5

A pulse of zGrad degrades Cxcr4b-GFP and stalls primordium migration transiently.

(A) Maximum-projected confocal images of the primordia in heat-shocked cxcr4b:cxcr4b-EGFP-IRES-Kate2-CaaX-p7; cxcr4b-/- embryos transgenic for hsp70l:zGrad (lower panels) or not (upper panels) at indicated time in min after the end of heat shock (31 hpf). Scale bar: 50 µm. (B) Quantification of Cxcr4b-EGFP-to-Kate2-CaaX ratios in the primordia of control (blue) and zGrad-expressing embryos (red) after the end of heat shock in min. Mean and SD are indicated. (C) Quantification of circularity of the primordia of control (blue) and zGrad-expressing embryos (red) after the end of heat shock in min. Mean and SD are indicated. (D) Quantification of the cumulative primordium migration distance in control (blue) and zGrad-expressing embryos (red) after the end of heat shock in min. Mean and SD are indicated. Inset shows magnification of the 30 min to 240 min time interval. **=p < 0.01. (E) Kymograph of the primordia in heat-shocked cxcr4b:cxcr4b-EGFP-IRES-Kate2-CaaX-p7; cxcr4b-/- embryos transgenic for hsp70l:zGrad (bottom) or not (top). Cxcr4b-EGFP is shown in green and Kate2-CaaX in red. Asterisk indicates the time interval in which Cxcr4b-EGFP is transiently degraded and the primordium transiently ceases to migrate
