Fig. 1. hrT morphant phenotypes. (A) Binding positions of the morpholino
antisense oligonucleotides, hrTMO(1) and hrTMO(2), to the hrT
transcript. The sequence of the control-MO is also shown. (B-E) Lateral views
with anterior towards the left. (B,C) The overall morphology of an uninjected
(B) and hrTMO(1)-injected (C) embryos at 24 hpf. (D,E) The overall morphology
of an uninjected (D) and hrTMO(2)-injected (E) embryos at 50 hpf. (F-I)
Lateral view with anterior towards the top. (F,G) Heart morphology of
uninjected embryo (F) and of hrTMO(1)-injected (G) embryo at 48 hpf. (H,I)
Higher magnification of F,G, respectively (v, ventricle; a, atrium). Live
(J,L,N,P) and green fluorescent (K,M,O,Q) pictures of embryos injected at the
shield stage with: (J,K) 0.1 ng of hrT-GFP RNA; (L,M) 0.1 ng of
hrT-GFP RNA plus 1.5 ng of hrTMO(1); (N,O) 0.1 ng of GFP
RNA; and (P,Q) 0.1 ng of GFP RNA plus 1.5 ng of hrTMO(1).
