Ectopic expression of <i>unc-4</i> in all six VC neurons in animals with mutations affecting chromodomain proteins and histone methyltransferases.

<p>(A) Expression of <i>uIs45</i> in <i>met-2(n4256)</i> and <i>met-1(n4337)</i> adults. Scale bar = 100 µm. (B) Illustration of the wild-type and ectopic <i>unc-4</i> expression pattern in adult animals. Filled circles represent cells that express <i>uIs45</i>. (C) The penetrance of the phenotype of <i>unc-4</i> ectopic expression in various mutants.
