The Unit also has found evidence of a common ancestor that links humans to sea stars.
Genes dictate many aspects of how living things look and act, but genes are also controlled. Epigenetics, is the study of mechanisms that determine whether a gene is active or not, and thus whether it has any effect on an organism. The Plant Epigenetics Unit studies epigenetic regulation in Arabidopsis and rice. It is also improving traits of rice crops by applying genomic information obtained by high-throughput sequencing technology.
