Col9α1 morpholino phenocopies the prp finfold phenotype while overexpression of col9α1 rescues prp. (A) A gene-specific morpholino (MO) targeting the splice site of col9α1 exon 5 caused the small-finfold phenotype in wild-type (WT) embryos. (B) The tail of a 2-day post-fertilization (dpf) uninjected WT embryo showing a normal finfold with radial actinotrichia (arrow). (C) A prp embryo showing a small finfold with short and sparse actinotrichia (arrow). (D) A WT embryo injected with the col9α1 MO developed the prp-like small-finfold and actinotrichia defects. (E) A prp embryo injected with the col9α1 plasmid developed a mosaic finfold with a prp-like portion in the dorsal half and a normal-looking portion in the ventral half where normal actinotrichia can be seen (arrow). Arrows, actinotrichia. Anterior, left; dorsal top.
