We presented several lines of evidence indicating that dorso–ventral asymmetry is apparent in zebrafish embryos by cleavage stages1, one of which showed that injection of three different morpholino oligonucleotides targeting three different squint (sqt) sequences cause severe disruption in dorsal structures. We concluded that the dorsal axis is evident by the 4-cell stage, and suggested that maternal Sqt and associated factors may function in zebrafish dorsal-axis formation1. Bennett et al. challenge our results obtained with morpholino oligonucleotides because they do not find a comparable defect in maternal and zygotic sqt mutants2.
