The Caenorhabditis elegans gene lin-26 is required to specify the fates of hypodermal cells and encodes a presumptive zinc-finger transcription factor.
The mutation lin-26(n156) prevents vulva formation in C. elegans by transforming the vulval precursor cells into neurons or neuroblasts. We have isolated and characterized three new lin-26 alleles, which result in embryonic lethality. These mutations cause a few other hypodermal cells to express a neural fate and most hypodermal cells to degenerate. lin-26 encodes a presumptive zinc-finger transcription factor. Our data indicate that lin-26 is required for cells to acquire the hypodermal fate.
