  • Unusual soybean coloration sheds a light on gene silencing
    on June 19, 2017 at 4:03 pm

    Today's soybeans are typically golden yellow, with a tiny blackish mark where they attach to the pod. In a field of millions of beans, nearly all of them will have this look. Occasionally, however, a bean will turn up half-black, with a saddle pattern similar to a black-eyed pea. New research indicates why. […]

  • We are more than our DNA: Discovering a new mechanism of epigenetic inheritance
    on April 27, 2017 at 3:12 pm

    The existence of transgenerational epigenetic inheritance has now been demonstrated among Drosophila fruit flies. By temporarily modifying the function of Polycomb Group (PcG) proteins--which play an essential role in development--the researchers obtained fruit fly lines having the same DNA sequence but different eye colors. An example of epigenetic inheritance, this color diversity reflects varying degrees of heritable, but reversible, gene repression by PcG proteins. It is observed in both transgenic and wild-type lines and can be modified by environmental conditions such as ambient temperature. […]
