Abstract |
Cilia and flagella are highly conserved organelles that have diverse motility and sensory functions. Motility defects in cilia and flagella result in primary ciliary dyskinesia (PCD). We isolated a novel medaka PCD mutant, jaodori (joi). Positional cloning showed that axonemal dynein intermediate chain 2 (dnai2) is responsible for joi. The joi mutation was caused by genomic insertion of the medaka transposon, Tol1. In the joi mutant, cilia in Kupffer's vesicle (KV), an organ functionally equivalent to the mouse node in terms of left-right (LR) specification, are generated but their motility is disrupted, resulting in a LR defect. Ultrastructural analysis revealed severe reduction in the outer dynein arms in KV cilia of joi mutants. We also found the other dnai2 gene in the medaka genome. These two dnai2 genes function either redundantly or distinctly in tissues possessing motile cilia.
