Fig. 3. lqf collaborates with the Notch pathway to regulate cardioblast development. Dorsal views of stage 16 wild-type (A), lqf^ARI (B), N^ts-1 (C), lqf^ARIDl³/lqf^ARI+ (D), N^ts-1;lqf^ARI/+ (E) and lqf^ARI neur¹/lqf^ARI+ (F) embryos labeled for cardioblasts. (A) Wild-type cardioblast pattern. (B,C) N^ts-1 embryos grown at 30°C (C), and lqf^ARI embryos grown at 18°C (B), exhibit near wild-type cardioblast patterns with very mild increases in cardioblast number. (D) N^ts-1;lqf^ARI/+ embryos grown at 30°C exhibit a clear increase in cardioblast number as do lqf Dl³/lqf^ARI+ (E) and lqf^ARI neur¹/lqf^ARI+ (F) embryos grown at 18°C. Anterior – left.
