Correction: Developmental Dynamics of X-Chromosome Dosage Compensation by the DCC and H4K20me1 in C . elegans

There are errors in the second and third sentences from the end of the Abstract. These sentences should read “H4K20me1 depletion in the set-1 mutant showed greater X derepression compared to equalization of H4K20me1 levels between X and autosomes in the set-4 mutant, indicating that H4K20me1 level is important, but X to autosomal balance of H4K20me1 contributes slightly to X-repression. Thus H4K20me1 is not only a downstream effector of the DCC.” The last sentence of the Introduction is incorrect. The sentence should read “Our results suggest that H4K20me1 levels are important for X chromosome dosage compensation, but H4K20me1 does not act only as a downstream effector of the DCC.”
