Early embryo of an Arabidopsis thaliana plant

Caption

Plants use chemical, or epigenetic, modifications to control the activity of their genes. Red and green mark epigenetic modifications in the DNA (gray on the left) of an early embryo of an Arabidopsis thaliana plant. Cold Spring Harbor Laboratory Professor & HHMI Investigator Rob Martienssen's team discovered one of the genes responsible for attaching these modifications at the right spots in the genome.
