Researchers find protein that silences genes

Studying the phenomenon of nucleolar dominance, in which one parental set of ribosomal genes in a hybrid is silenced, Craig Pikaard, Ph.D., Washington University professor of biology in Arts & Sciences and colleagues have identified the protein HDA6 as an important player in the silencing.
