title: HPL-2/HP1 prevents inappropriate vulval induction in Caenorhabditis elegans by acting in both HYP7 and vulval precursor cells.
abstract: A current model for Caenorhabditis elegans vulval cell fate specification is that SynMuv genes act redundantly in the hyp7 hypodermal syncytium to repress the LIN-3/EGF inducer and prevent ectopic vulval induction of vulva precursor cells (VPCs). Here we show that the SynMuv gene hpl-2/HP1 has an additional function in VPCs, where it may act through target genes including LIN-39/Hox.
