Embryos with rps9 deficiency display morphological abnormalities. (A-E) Overall morphological phenotype of rps9 deficient embryos. At 24 hpf (A and A’), smaller eyes and abnormal hindbrain (arrowhead) appear in the head region. By 36 hpf (B), enlarged hindbrain (arrowhead) becomes apparent and pigment is reduced. From 48 hpf to 4 dpf (C-E), edema (arrowhead) is gradually developed in the pericardial region, accompanied with shortened trunk. (F) Cartilage fails to grow in the pharyngeal arch in rps9 mutant embryos.
